Our Complete Betting Guides

Each guide below is a full-length, step-by-step explanation of a specific betting topic – written for Indian bettors, with ₹-denominated examples, cricket and ISL scenarios, and local legal context.

📘 Arbitrage Calculator – How to Use One and What It Actually Tells You

Arbitrage betting (or “arb betting”) is the practice of placing bets on all possible outcomes of an event across different bookmakers, at odds that guarantee a return regardless of the result. An arbitrage calculator is the tool that tells you exactly how to split your stake across both sides.

This guide covers the maths behind arb percentages, how to spot genuine opportunities across IPL markets, and two worked strategies – equal return and weighted arb. It also covers the operational risks: odds shifting before both bets are placed, bookmaker account restrictions, and how to identify error odds before they get voided.

• What you will learn: How arb percentage is calculated, how to use a calculator step by step, two betting strategies with worked ₹ examples, and what risks to watch for.
• Best read if: You want to understand how professional bettors approach pricing discrepancies between platforms.

📗 How Betting Odds Work – Decimal, Fractional, and American Odds Explained

Odds are the foundation of everything in sports betting. They tell you simultaneously how likely a bookmaker thinks an outcome is, and how much you will receive if that outcome occurs. This guide takes all three formats – decimal (most common in India), fractional (used on UK platforms), and American/moneyline – and explains each one from scratch.

Worked examples include IPL matches with ₹ stakes, a Premier League three-way market, and a T20 international between India and Australia in moneyline format. The guide also explains implied probability, the bookmaker’s margin (overround), how and why odds move, and the TDS implications of winnings under Indian tax law.

• What you will learn: How to calculate returns in all three formats, what implied probability means, why odds are never perfectly fair, and how market movements work.
• Best read if: You are new to betting and want to understand what every number on a betting slip actually means before you place anything.

📙 Double Chance Betting – 1X, X2, and 12 Explained

Double chance betting is a football market (and, in limited cases, a Test cricket market) that lets you cover two of three possible outcomes with a single bet. Instead of backing a win, draw, or away win separately, you choose a pair: home team or draw (1X), draw or away win (X2), or either team wins with no draw (12).

This guide explains all three variants with ISL examples (Mumbai City, ATK Mohun Bagan, Kerala Blasters), a Merseyside Derby X2 scenario, and a worked accumulator showing how double chance can stabilise a multi-leg bet. It also covers live betting applications, the 90-minute settlement rule, and where the 12 variant is statistically riskiest.

• What you will learn: When each variant makes sense, how odds compare against standard 1X2, how to use double chance in accumulators, and why Test cricket is the only cricket format where this market applies.
• Best read if: You follow ISL or Premier League football and want a market that covers more than one result.

📕 Over/Under Betting – Totals Explained Across Cricket and Football

Over/under betting (also called totals betting) asks one question: will a specific measurable outcome in a match finish above or below a number set by the bookmaker? It is entirely independent of who wins – you are betting on volume, not on a result.

This guide covers over/under in IPL cricket (total match runs, first innings runs, total sixes, wicket markets), Test cricket, ISL football (goals), and Premier League football, with full worked examples at each type. It explains how total lines are set, why the .5 is important, what a push is, how alternate totals work, and what factors move cricket totals specifically – pitch type, toss result, dew, team composition.

• What you will learn: How to read and calculate totals bets in cricket and football, what factors drive the line, how live totals betting works, and how to avoid the most common mistakes.
• Best read if: You have a strong view on how a match will play out in terms of scoring volume rather than which side will win.

A-Z Betting Glossary

The terms below are listed alphabetically. Where a term links directly to one of our full guides above, that is noted. All examples use Indian context, ₹ denominations, or globally familiar scenarios where relevant.

A

Accumulator (Acca / Kombi)
A single bet that combines multiple individual selections. All selections must win for the bet to pay out. The odds of each leg are multiplied together, producing potentially large returns from a small stake. One losing leg causes the entire bet to fail. Also called a “parlay” on some international platforms.

Example: Backing Mumbai City, Kerala Blasters, and Bengaluru FC all to win in the same round of ISL fixtures – all three must win for the bet to return anything.

Arbitrage (Arb / Sure Bet / Surebet / Miraclebet)
The practice of placing bets on all outcomes of an event across different bookmakers, at odds that – when combined correctly – guarantee a positive return regardless of the result. The discrepancy is created by different bookmakers pricing the same event differently.

See our full guide: Arbitrage Calculator.

Asian Handicap
A form of handicap betting, common in football, that eliminates the draw by giving one team a virtual head start or deficit. It produces a two-outcome market rather than three. Lines can be whole numbers, half numbers, or quarter numbers (which split the stake across two lines).

Example: India –1.5 vs Australia +1.5. Backing India means they must win by two or more goals.

B

Bankroll
The total amount of money a bettor has set aside specifically for betting. Sensible bankroll management typically means limiting each individual bet to a fixed percentage of the total – commonly 1–5% – to avoid depleting the entire amount on a losing run.

Bookmaker (Bookie / Platform)
The company or platform that sets the odds and accepts wagers. Bookmakers build a margin into their pricing (see: Overround) to ensure a structural advantage over time, regardless of individual outcomes.

Both Teams to Score (BTTS)
A football market in which you bet on whether both teams will score at least one goal during the match. “Yes” means both sides find the net; “No” means one or both sides are shut out. Entirely independent of who wins – a 1–0 result is a BTTS “No” even though it produced a goal.

Bust (Going Bust)
When a bettor loses their entire bankroll. Most commonly caused by placing oversized stakes relative to the bankroll, chasing losses, or placing bets without understanding the implied probability.

C

Cash Out
A feature offered by most major platforms that allows you to settle your bet before the event concludes, for a return somewhere between your full profit and your full loss. Useful for locking in partial profit when a bet is going well, or for reducing a loss when it is going poorly. The offered cash-out amount is calculated in real time.

Correct Score
A market in which you predict the exact final scoreline of a match. Because there are many possible outcomes, correct score odds are typically high – but so is the probability of losing. Common in football.

Cover
In handicap betting, “covering the spread” means a team has performed well enough relative to the handicap for the bet to win. If Mumbai City are giving a –1.5 handicap and win 2–0, they have “covered” it.

D

Dead Heat
When two or more selections finish in exactly the same position in an event – most common in horse racing and golf. Returns are typically divided by the number of tied selections. Platforms have specific dead heat rules which should be checked before placing.

Decimal Odds
The most widely used odds format on Indian-facing betting platforms. The number shown is your total return per ₹1 staked, including your original stake. Odds of 2.00 mean you receive ₹2 for every ₹1 bet – your ₹1 stake returned plus ₹1 profit.

See our full guide: How Betting Odds Work.

Dew Factor
Specific to cricket betting in India. Evening T20 matches – particularly in Mumbai, Delhi, and other high-humidity venues – are often affected by dew on the outfield. Dew makes it harder for spinners to grip the ball and generally produces higher second-innings scores. Bookmakers often adjust total run lines in anticipation of dew.

Double
An accumulator with exactly two selections. Both must win. The return from the first selection is reinvested as the stake for the second.

Double Chance
A football betting market that covers two of three possible outcomes (home win, draw, away win) in a single bet. The three options are 1X (home or draw), X2 (draw or away), and 12 (either team wins, no draw). See our full guide: Double Chance Betting.

Draw No Bet (DNB)
A market in which you back one team to win, but receive your stake back as a refund if the match ends in a draw. Sits between a double chance and a standard match winner in terms of risk. Odds are typically lower than the outright win but higher than the corresponding double chance option.

Drift
When odds on a selection increase (lengthen) over time before an event. This usually indicates that money has moved away from that selection – either because of negative news (injury, poor conditions) or because bettors favour the other side.

E

Each Way (E/W)
A bet comprising two parts: a win bet and a place bet (typically top 2–4 finishers, depending on the event). Stake is doubled. Common in horse racing and golf. Less relevant to cricket or football betting.

Edge
A bettor’s perceived advantage over the bookmaker’s implied probability. If you believe Team India has a 60% chance of winning a T20 match but the bookmaker’s implied probability is only 50%, your “edge” is approximately 10 percentage points on that outcome.

Even Money (Evens)
Odds of 2.00 in decimal, 1/1 in fractional, or +100 in American. A ₹500 stake at evens returns ₹1,000 total – profit equals the stake exactly.

F

Favourite
The outcome the bookmaker considers most likely to occur. Reflected in the lowest odds. In IPL cricket, Team India is usually the favourite against most opponents at home.

Fixed Odds
Bets placed at a specific, agreed price that does not change after the bet is placed, regardless of how the market moves. Distinct from starting price betting (common in horse racing) where your odds are determined at the time the event begins.

Flat Betting
A staking strategy in which the bettor places the same fixed ₹ amount on every bet, regardless of perceived confidence. Considered a sound discipline for beginners because it prevents oversizing on “sure things” that still lose.

Form
A team or player’s recent results and performance trend. In cricket betting, “form” often refers to batting averages, strike rates, recent scores, or bowling economy over the last five or ten matches. Checking form before betting is basic due diligence.

Fractional Odds
The traditional UK odds format. Expressed as A/B (e.g. 5/2, 10/1), where A is the profit earned for every B staked. Your stake is returned on top of the profit. Odds of 5/1 mean a ₹1,000 bet returns ₹6,000 total (₹5,000 profit plus the ₹1,000 stake back).

G

Goal Line
Another term for the over/under total in football markets. “Goal line 2.5” means the total is set at 2.5 goals for the match.

Goliath
A large system bet comprising 8 selections and 247 individual bets. Rarely used by recreational bettors due to the high total stake cost.

H

Handicap Betting
A market in which one side is given a virtual advantage or disadvantage to level the playing field. Handicap bets produce more evenly priced markets. Used heavily in football, cricket (run lines), and rugby.

Asian Handicap (see above) is a specific variant that eliminates draws.

Hedge
Placing a second bet on the opposite side of an existing wager to reduce exposure or lock in profit. Often used when a long-odds accumulator has come through several legs and the final leg represents a meaningful risk.

Home/Away/Draw (1X2)
The standard three-outcome football market. 1 = Home win, X = Draw, 2 = Away win. The most fundamental football betting market globally.

I

Implied Probability
The probability of an outcome as implied by the bookmaker’s odds. Calculated by dividing 1 by the decimal odds and multiplying by 100. Odds of 2.50 imply a 40% probability (1 ÷ 2.50 = 0.40 = 40%). If you believe the true probability is higher than this, the bet may represent value.

In-Play Betting (Live Betting)
Placing a bet while the event is already underway. Odds shift in real time based on what is happening on the pitch or field. Available for IPL matches (over-by-over), Premier League football, and most major sporting events. Useful for reacting to match developments but requires speed, as prices move fast.

K

Kelly Criterion
A mathematical formula for calculating the optimal stake size relative to your perceived edge and bankroll. Designed to maximise long-term growth while avoiding excessive risk. Advanced bettors use it; beginners are usually better served by flat betting first.

Kombis
A colloquial term used in India (and parts of South-East Asia) for accumulator bets. Same concept – multiple selections, all must win.

L

Lay Bet
A bet placed against an outcome occurring, rather than for it. Only available on betting exchanges (where bettors trade against each other rather than against a bookmaker). If you “lay” a team, you are effectively acting as the bookmaker – you win if they do not win.

Line Shopping
The practice of comparing odds across multiple bookmakers before placing a bet to find the best available price for the same outcome. Standard practice among experienced bettors. The same match can carry meaningfully different odds across platforms.

M

Margin (Overround / Vig / Juice)
The bookmaker’s built-in profit edge, embedded into the odds. When you add up the implied probabilities of all outcomes in a market, they exceed 100%. That excess is the margin. A typical football 1X2 market carries a 5–8% margin; tighter markets like cricket head-to-head can be 3–5%. See also: Overround.

Match Betting
The simplest form of sports betting – picking the winner of a match or event outright. In cricket (T20 and ODIs), this is a two-outcome market. In football and Test cricket, it is three-outcome.

Moneyline (American Odds)
The US standard odds format. Positive numbers (+150) indicate how much profit a ₹100 bet earns. Negative numbers (–180) indicate how much you must stake to earn ₹100 profit.

O

Odds
The numerical expression of how likely a bookmaker considers an outcome, and how much they will pay if that outcome occurs. Odds can be expressed as decimals, fractions, or moneyline numbers.

Odds-Against
A bet where the potential profit exceeds the stake. Decimal odds above 2.00, fractional odds where the left number exceeds the right (e.g. 5/1, 10/3).

Odds-On
A bet where the potential profit is less than the stake. Decimal odds below 2.00, fractional odds where the right number exceeds the left (e.g. 1/2, 4/7). The bookmaker considers this outcome more likely than not.

Over/Under (Totals)
A market based on the combined measurable output of both sides in a match – most commonly runs in cricket or goals in football. You bet whether the final figure will exceed (Over) or fall short of (Under) the bookmaker’s line.

See our full guide: Over/Under Betting.

Overround
The sum of implied probabilities across all outcomes in a market. A perfect market would sum to 100%. In practice, bookmakers price it above 100% – the excess is their margin. Also called the “vig”, “juice”, or “margin”.

P

Parlay
The international/American term for an accumulator. Multiple selections combined into a single bet; all must win.

Payout
The total amount returned to the bettor if their bet wins. Includes both profit and the original stake (in decimal odds, payout = stake × odds).

Pitch Report
Specific to cricket betting. The on-site assessment of the playing surface released before a match begins. Pitch type (dry and spin-friendly vs. flat and pace-friendly) is one of the most significant inputs into IPL run total lines. A dusty, turning surface in Chennai typically means lower run lines than a belter in Bengaluru.

Push
When the final result of a bet lands exactly on the line set by the bookmaker – most relevant when whole-number (non-.5) totals are used. In a push, neither Over nor Under wins and the stake is returned. Bookmakers use .5 lines specifically to eliminate pushes.

R

Return on Investment (ROI)
The percentage profit earned relative to the total staked. An ROI of 5% on ₹10,000 staked means ₹500 profit. In arbitrage betting, ROI per arb typically sits between 1–5% for genuine market discrepancies.

Run Line
The cricket equivalent of a point spread or handicap in team sports. A bookmaker might offer Team India –12.5 runs on the run line, meaning they must win by 13 or more runs for that side of the bet to pay out.

S

Single Bet
The simplest bet type – one selection, one outcome. No other legs, no multiplication. The most straightforward way to learn how odds and returns work before moving into accumulators or more complex markets.

Stake
The amount of money placed on a bet. Distinct from “return” (which includes the stake back) and “profit” (which is the return minus the stake).

Sure Bet (Surebet / Arb)
See: Arbitrage. A situation where odds across multiple bookmakers allow all outcomes to be covered at a combined implied probability below 100%, guaranteeing a positive return.

T

TDS (Tax Deducted at Source)
An Indian tax regulation under Section 194B of the Income Tax Act. Winnings from games of chance – including online betting – above ₹10,000 per transaction are subject to 30% TDS, deducted at the time of payout by the platform. Relevant to every Indian bettor, regardless of which market they use.

Treble
An accumulator with exactly three selections. All three must win.

U

Underdog
The outcome the bookmaker considers least likely to occur. Reflected in the highest odds. Backing an underdog carries greater risk but higher potential return.

Under
The position in an over/under market that wins if the final total falls below the bookmaker’s line.

V

Value Bet
A bet where you believe the true probability of an outcome is higher than the implied probability in the bookmaker’s odds. If the bookmaker implies a 40% chance (odds of 2.50), but you believe the true probability is 50%, that is a value bet. Finding value consistently – rather than backing favourites or big odds impulsively – is the foundation of any long-term analytical approach to betting.

Vigorish (Vig / Juice)
See: Margin / Overround. The bookmaker’s built-in profit. Understanding the vig helps you understand why the house has a structural advantage on every market.

Void Bet
A bet that is cancelled and the stake returned, typically due to: a match being abandoned, a pricing error being identified by the bookmaker, or a selection being withdrawn before an event. Bookmakers can void bets on error odds (e.g. a heavy favourite listed at 20.00 when the correct price is 1.20) even after they have been placed.

W

Wager
Another word for a bet. The amount wagered is the stake.

Weighted Arb
A variation of arbitrage betting in which the bettor intentionally stakes more on the outcome they believe is more likely, while still covering the other side. Increases potential profit if the favoured outcome wins, but reduces it (to break-even or a small loss) if the other outcome occurs.

Wicket Market
A cricket-specific over/under market. The bookmaker sets a line for the total number of wickets in a match or innings. Typical T20 international totals: 11.5–14.5 across both innings combined. A spin-friendly pitch in India tends to push this line higher.

A Note on Responsible Engagement

This glossary and the guides linked above are built on the premise that understanding a subject fully – before committing money to it – leads to better decisions. That applies as much to betting as it does to any other financial activity.

A few principles worth keeping close:

• Set a budget before you start and treat it as the cost of the activity, not as money you expect to recover
• Never bet money you cannot afford to set aside entirely
• If betting is affecting your finances, relationships, or wellbeing, seek help from iCall (India’s mental health helpline: 9152987821) or a trusted person in your life
• Understanding markets and odds does not guarantee profit – it reduces uninformed decisions

Frequently Asked Questions

What is the most important betting concept for a beginner to understand?
Implied probability. Every set of odds carries a hidden percentage – the bookmaker’s estimate of how likely that outcome is. Before placing any bet, calculate the implied probability and ask yourself honestly whether you think the real likelihood is higher than that. If you do, you may have a value bet. If you do not, think carefully before placing.

What does “the market” mean in sports betting?
The term “the market” refers to the collective activity of all bookmakers and bettors pricing and betting on a given event. When people say “the market moved”, they mean odds shifted across multiple platforms in the same direction – usually because significant money entered on one side, or new information (team news, injury, weather) changed the consensus view.

Is there a difference between a “bet” and a “wager”?
No. The terms are interchangeable. Some Indian platforms and formal writing use “wager”; most casual conversation uses “bet”. The stake is the amount placed; the bet or wager is the act of placing it.

What does “settling” a bet mean?
Settlement is the process of calculating and paying out (or deducting) the result of a bet after the relevant event is concluded. Most platforms settle bets automatically within minutes of the final result. Some markets – particularly those involving statistics (top scorer, most sixes) – may take longer to settle.

Can I bet on both cricket and football on the same platform?
Most international-facing platforms cover both. Cricket markets (especially IPL and international T20s) are widely available alongside Premier League, Champions League, ISL, and La Liga football markets. Specific market availability varies by platform and region.

What is the difference between a bookmaker and a betting exchange?
A bookmaker sets the odds and acts as the counterparty – you bet against the bookmaker. A betting exchange is a peer-to-peer marketplace where bettors trade against each other; the exchange charges a commission on winnings. On an exchange, you can also “lay” a bet (back an outcome NOT to happen). Exchanges often offer slightly better odds because the exchange’s margin is typically lower than a bookmaker’s overround.
