Introduction to Local Card Games
Card games familiar to Bangladeshis are now available to play online — an easy guide for beginners.
Teen Patti
Three cards are dealt each round. The player with the highest-value hand wins. Play against a live dealer or against other players.
Tip: Try to make a Pair or a Straight.
Andar Bahar
The dealer places a joker card. Players bet on whether the next card of the same value will come from 'Andar' (left side) or 'Bahar' (right side). Simple and fast.
Tip: The easiest game for beginners.
Callbreak
4 players with a 52-card deck. At the start of each round, you declare how many hands you expect to win. Spades are always trump. Played against other players.
Tip: Hold on to high cards and spades.
Ludo / Rummy
In Ludo, roll the dice to move your pieces — get all your pieces home first to win. In Rummy, form card sets or runs. Both are played against other players.
Tip: In Rummy, build sequences quickly.
Understanding RTP and House Edge
RTP (Return to Player) is the percentage of total bets a game returns to players on average over the long run. If a slot has an RTP of 96%, you can expect an average return of ৳96 for every ৳100 wagered. However, this is an average across millions of spins — results in a single session can be much higher or lower.
RTP typically varies by game type. Slot games generally range from 92% to 98%. Blackjack played with correct strategy can reach close to 99%. Roulette usually falls between 94% and 97%, with European Roulette offering a slight advantage.
House edge is the opposite of RTP — it represents the casino's average advantage. A 96% RTP means a 4% house edge. The lower the house edge, the less you are likely to lose over the long term.
Volatility (or variance) is the level of risk in a game. High-volatility games pay out less frequently but with larger rewards. Low-volatility games pay smaller amounts more often. Choose a game that matches your budget and playing style.
Approximate RTP by Game Type
These are theoretical averages — not a guarantee for any specific game.
Betting Terms in Plain Language
New players are often confused by these words — here they are explained in simple terms.
RTP (Return to Player)
The percentage of total bets that a game returns to players over the long run. The higher, the better.
House Edge
The casino's average advantage as a percentage. The lower the house edge, the less advantage the casino has and the better it is for the player.
Wager / Stake
The amount of money you place on each bet is the stake. Wagering requirement refers to how many times you must bet before you can withdraw a bonus.
Odds
A numerical expression of the likelihood of an outcome. Higher odds mean a bigger reward but a lower chance of winning.
Parlay / Accumulator
Combining multiple bets into one. Win them all and you get a large reward; lose any one of them and the entire bet is lost.
Live Bet
Placing a bet in real time while a match or game is in progress. Odds change every moment, so quick decisions are essential.
Cashout
The option to settle a bet at its current value before the match ends. Used to reduce risk or lock in a guaranteed profit.
Bankroll
The total amount of money set aside for playing. Proper bankroll management is the foundation of responsible gaming.
Volatility
The level of risk in a game. High volatility means bigger rewards but less frequently. Low volatility means smaller but more regular wins.
Free Spin
Free slot spins received as a bonus. A chance to win without spending your own money, though wagering conditions may apply before winnings can be withdrawn.
Spread
In sports betting, a hypothetical points difference between teams. In spread betting, the margin matters, not just the win or loss.
Wagering Requirement
The condition specifying how many times you must wager in total before a bonus can be withdrawn. The welcome bonus wagering requirement at ab666 is 20x.
Account Verification Process
KYC (Know Your Customer) is the process for account security and compliance. It confirms your identity and protects your account from unauthorized use.
Clear photos of the front and back of your NID card.
A utility bill or bank statement (within the last 3 months).
A selfie holding your NID card — taken in clear lighting.
Usually completed within 1 to 24 hours.
Once verification is complete, you can claim bonuses and withdraw any amount without any restrictions.
