Betting Glossary
-
RTP (Return to Player)
RTP is the percentage of total wagered money that a slot or casino game pays back to players over time. A game with 96% RTP returns ৳96 for every ৳100 staked on average.
-
House Edge
The house edge is the mathematical advantage a casino holds over players in any given game. It is the inverse of RTP — a 4% house edge means the casino retains 4% of all wagers over time.
-
Wager / Stake
A wager or stake is the amount of money placed on a single bet. Setting a comfortable stake per round helps manage your bankroll and extend your playing time on gt99b.
-
Odds
Odds represent the probability of an outcome and determine how much a winning bet pays. Decimal odds of 2.00 mean you receive double your stake if your bet wins.
-
Parlay / Accumulator
A parlay combines multiple individual bets into one. All selections must win for the parlay to pay out, but the combined odds multiply to create significantly larger potential winnings.
-
Live Bet
A live bet (in-play bet) is placed after a match or game has already started. gt99b offers live cricket betting with odds updated ball-by-ball throughout BPL and international matches.
-
Cashout
Cashout allows you to settle a bet before the final result is determined. You can lock in a partial profit or minimise losses if the game is not going in your favour.
-
Bankroll
Your bankroll is the total amount of money you have set aside specifically for gambling. Responsible bankroll management — only betting a small percentage per session — is key to long-term enjoyment.
-
Volatility
Volatility (or variance) describes how often and how much a slot pays out. High-volatility slots pay less frequently but in larger amounts; low-volatility slots provide smaller, more regular wins.
-
Wagering Requirement
A wagering requirement specifies how many times you must wager a bonus before you can withdraw the funds. For example, a ৳1,000 bonus with a 20x requirement means you must stake ৳20,000 total before withdrawal.
