Betting Glossary
Learn the common terms used in online casino and betting — explained in plain language for new players.
RTP (Return to Player)
A theoretical calculation of what percentage of total wagers a game returns to players over the long term. It is a statistical average — results can vary from session to session.
House Edge
The mathematical advantage the casino holds on every game. The lower the house edge, the better the player's statistical position.
Wager / Stake
The amount of money you place on a single bet is your Stake or Wager. For bonuses, the terms will state how many times you must wager the bonus amount before withdrawing.
Odds
The ratio between the probability of an event and the potential reward. The higher the odds, the larger the potential payout — but the lower the probability.
Parlay / Accumulator
Combining multiple bets together — if all bets win, the payout is large, but if one loses, the entire bet is lost.
Live Bet (In-Play Betting)
Placing bets in real time while an event is in progress. You get the opportunity to make decisions based on the score and momentum.
Cashout
The option to settle a bet before the event ends. You can take a partial or full cashout to secure a guaranteed return.
Bankroll
The total amount of money set aside specifically for gaming. Proper bankroll management is the foundation of responsible gaming.
Volatility
The frequency and size of wins in a game. High-volatility games deliver larger wins less often; low-volatility games deliver smaller wins more frequently.
Free Spin
The opportunity to spin for free in a slot game — usually triggered when specific symbols appear together or awarded as a bonus.
Wagering Requirement
The number of times you must wager the bonus amount before you can withdraw it. For the welcome bonus at sb666, this is 25 times.
Spread
A method in sports betting used to level the playing field between two teams. The weaker team is given a head start of a few points.
Account Verification Process
KYC (Know Your Customer) verification is a mandatory part of every trustworthy platform. It keeps your account secure and ensures that no one can use your account without authorization.
Upload a clear photo of your National ID (NID) or passport. Make sure all details are clearly visible.
A copy of a utility bill, bank statement, or government letter — the date must be within the last three months.
Take a selfie holding your NID so that both your face and the ID are clearly visible.
Verification is usually completed within 1–24 hours. After that, your withdrawal limit increases and your account becomes fully active.
