Betting terms and glossary
Knowing these terms will make any game and betting much easier to understand.
RTP (Return to Player)
RTP is the average percentage of total wagers that a game returns to players over the long term. For example, 96% RTP means an average of ৳96 may come back for every ৳100 wagered.
House Edge
The mathematical advantage held by the casino is called the house edge. The lower it is, the more favorable the conditions are for the player. Baccarat has a relatively low house edge.
Wager / Wagering
The condition of placing a specified amount in bets before a bonus can be withdrawn is called a wagering requirement. At t5666 this is only 25 times the bonus amount.
Stake
The amount of money placed on each bet is called the stake. Setting your stake according to your own means is part of healthy bankroll management.
Odds
Expressing the probability of an event occurring as a number is called odds. In betting, the higher the odds, the greater the potential payout, but the lower the probability.
Parlay / Accumulator
A method of placing a combined bet on multiple matches or events. If you win each event the reward multiplies, but if any one of them loses the entire bet is lost.
Live Bet
The ability to place bets in real time while a match is in progress is called a live bet or in-play betting. It gives you the chance to make decisions based on the score and momentum.
Cash Out
The option to take a set amount before the outcome of a bet is confirmed. This is especially important in crash games.
Bankroll
The total money set aside for playing is called a bankroll. Experts recommend spending no more than 5% of your bankroll on any single bet.
Volatility
The measure that determines the frequency and size of wins in a game. High volatility means fewer but larger wins; low volatility means more frequent but smaller wins.
Free Spin
Free slot spins received as a bonus. You can spin without spending your own money and winnings are generally credited to your account.
Spread
In handicap betting, the imaginary point difference between two teams. The stronger team must be ahead by a set number of points against the weaker team.
Play on mobile
t5666 is fully browser-based — play on any Android or iPhone device without downloading any app. Works on low data, and bets load fast.
