Betting Glossary
New to betting? Here are the key terms every player should know.
Return to Player — the theoretical percentage of all wagered money a game pays back over time. A slot with 96% RTP returns ৳96 for every ৳100 wagered on average.
The mathematical advantage the casino holds over the player, expressed as a percentage. European Roulette has a 2.7% house edge; Baccarat Banker bet has 1.06%.
The amount of money you put into a bet or spin. Your stake is at risk each round; returns are calculated as a multiple of your original stake.
A multi-selection bet where all picks must win for the bet to pay out. Odds multiply together, so a 5-team accumulator can return 50x your stake — but one wrong result loses it all.
A bet placed while a match or game is in progress. Live odds update in real time as the action unfolds — popular for cricket innings betting on sb666.
A feature allowing you to settle a bet early — before the event ends — for a portion of the potential winnings. Use it to lock in profit or cut losses mid-match.
The total funds you have set aside specifically for gambling. Responsible players never wager more than 1–5% of their bankroll on a single bet.
Describes how often and how large a slot or game pays out. High-volatility games pay big but rarely; low-volatility games pay small amounts frequently.
The number of times you must wager a bonus amount before withdrawing winnings. A ৳1,000 bonus with 30x wagering requirement means you must bet ৳30,000 total before cashing out.
A bonus round allowing you to spin a slot reel without using your own money. Free spins are often awarded as part of a welcome bonus or in-game scatter feature.
