Betting Words Defined

Gambling has its own vocabulary, and a single unfamiliar word can make an otherwise clear article hard to follow. This page collects the terms that come up most often in our entries, each explained in a sentence or two. It is a reference, not a lesson, so feel free to jump to the word you need.

Slot terms

Reel

One vertical column of symbols on a slot screen. Most online slots show five, though layouts vary widely.

Payline

A path across the reels on which matching symbols form a win. Some games replace fixed lines with "ways to win" that count matching symbols on adjacent reels.

Paytable

The screen that lists what each symbol combination pays and explains the features. It is the best place to learn a game.

Wild

A symbol that stands in for others to help complete a win.

Scatter

A symbol that usually pays or triggers a feature wherever it lands, regardless of lines.

Multiplier

A number that scales a win after it has landed. Explained in full in our multiplier entry.

Return to player (RTP)

A long-run figure published by the developer describing how much of all money staked a game pays back over a very large number of spins. It says nothing reliable about one session.

Volatility

How unevenly a game spreads its wins. Higher volatility means longer dry spells and larger, rarer prizes.

Hit frequency

The share of spins that return any win at all, including wins smaller than the stake.

Random number generator (RNG)

The software that decides each outcome independently of earlier spins.

Sports-betting terms

Market

A question you can bet on, such as the match result or the exact final score.

Odds

The price of a selection, showing what a winning bet returns. Odds always include a margin for the bookmaker.

Margin

The share built into a set of prices that favours the operator. Also called the overround or vig.

Settlement

How and when a bet is graded as won, lost or void under the operator's rules.

Regular time

In football, ninety minutes plus stoppage time. Most markets ignore extra time and penalties.

Void

A bet cancelled with the stake returned, often after a postponed or abandoned event.

Correct score

A market on the exact final score. See our correct score entry.

Bankroll and safer-play terms

Bankroll

The money set aside purely for gambling, kept apart from everyday funds.

Stake

The amount placed on a single spin or bet.

Loss limit

A cap on net losses over a set period, after which play stops.

Deposit limit
