Stake — The amount of money you wager on a bet.

Odds — The number that determines your potential return. Common formats: decimal (e.g., 2.50), fractional (e.g., 5/2), and American/Moneyline (e.g., +150 or -150).

Implied probability — The chance suggested by the odds. For decimal odds, implied probability = 1 / decimal odds (e.g., 2.50 = 40%).

Moneyline — A bet on which team or competitor will win outright. American moneyline shows favourites with a minus sign (e.g., -150) and underdogs with a plus (e.g., +130).

Point spread (handicap) — A margin set by the bookmaker to level a matchup. A favourite giving -3 must win by more than 3 points for a bet on them to win; a +3 underdog wins if they lose by less than 3 or win outright.

Total / Over-Under — A bet on the combined score or total (e.g., over 2.5 goals). If the actual total is higher, the over wins.

Parlay / Accumulator — A single bet linking multiple selections. All selections must win for the parlay to pay out. The odds multiply together.

Futures — Long-term bets on events that conclude in the future (champion of a league, season awards). They may be settled before the end in some situations—check the market rules.

In-play / Live betting — Betting after an event has started, with odds that change in real time.

Vig / Juice — The bookmaker’s commission built into the odds. It’s why implied probabilities of all outcomes exceed 100%.

Decimal odds example: Odds 2.50, stake $10 → return = 10 × 2.50 = $25 (profit $15). Implied probability = 1 / 2.50 = 0.40 (40%).

Fractional odds example: 5/2. A $2 stake returns $7 total (stake + $5 profit). To convert to decimal: (5/2) + 1 = 3.50.

American odds example: +150 means a $100 stake wins $150 profit (return $250). -150 means you must stake $150 to win $100 profit.

Parlay example: three decimal selections at 1.80, 2.00, and 1.50 with a $10 stake → combined odds = 1.80 × 2.00 × 1.50 = 5.40 → return = $10 × 5.40 = $54.

Timeframe for results: Some markets are based on a specific period (e.g., "90 minutes" for football excludes extra time and penalties), while others include extra time or overtime. Always check the market description.

Postponed or abandoned events: Many operators void bets if an event is cancelled or not completed within a specified timeframe, but some markets might stand if a result is declared by the organiser. Terms vary by operator and jurisdiction.

Player props and official stats: These are usually settled using the official scorer or stat provider named in the market rules. If an official source revises a stat after the event, settlements may be adjusted accordingly.

Dead heat: When competitors tie (e.g., horses finish in a dead heat), many bookmakers apply a dead-heat rule that reduces winning stakes proportionally. The usual practice divides your stake by the number of tied participants for the winning portion, but exact handling differs between operators.

Void and push: A push occurs when the outcome lands exactly on the line (e.g., a -3 spread where the favourite wins by 3) and typically results in the stake being returned. A void is when a bet is cancelled under the market rules and the stake is returned; void conditions differ between markets and operators.

Cash out: Some operators offer a cash-out option to settle a bet early at an offered price. This is discretionary and may not be available for all markets.

Read the market rules and the operator’s settlement policy before placing a bet, especially for props, futures, and live markets.

Know whether a market is settled on regulation time or includes extra time/overtime.

Keep stakes affordable and avoid treating betting as a source of income; outcomes are uncertain and losses can occur.

What does "juice" mean? Juice (or vig) is the bookmaker’s margin built into the odds. It reduces the payout relative to true probability.

What happens if a match is postponed? Settlement depends on the operator’s rules. Some markets are voided if the match is not played within a specific time window; others may stand if a result is eventually declared. Check the terms for that market.

How are player statistics settled? Most bookmakers use a named official data provider. If the official provider revises a stat, your bet may be settled according to the revised official record.

Can I cancel or change a bet? Generally no—most bets are final once accepted. Some operators allow cancellation within a short window, but this is not standard. Check the operator’s acceptance and amendment policy.
