Local Card Games

Teen Patti
Each player is dealt three cards and bets on whose hand is the strongest. A trail (three of a kind) is the highest, followed by a sequence.
Played against other players; a live dealer is often present as well.
Andar Bahar
One card is placed on the table; you bet on whether the next card of the same number will fall on "Andar" (left) or "Bahar" (right).
Played in real time with a live dealer. Fast rounds — each hand is over in a matter of seconds.
Callbreak
Four players with a 52-card deck; each round you must declare how many tricks you will win. Spades are always the trump suit.
Played against other players; winning depends on skill and strategy.
Ludo / Rummy
The familiar Ludo is now online against other players. In Rummy, you are dealt 13 cards and must form sets and sequences.
Both games are in multiplayer format — no live dealer; players compete against each other.
Live Betting & Cash Out
Live betting, or in-play betting, means you can place bets even after a match has started. In cricket, the odds change with every over, every wicket and every boundary. In football, a goal brings an instant change to the markets.
Cash out is the option to close your bet before the match ends and receive a confirmed amount. If it feels like the situation is turning against you, you can cash out to reduce your loss. Equally, if you are in a strong position, you can lock in a profit early.

RTP and House Edge Explained
RTP (Return to Player) is the average percentage of total bets a game returns to players over the long term. For example, if a slot has an RTP of 96%, it means that over the long term, an average of ৳96 is returned for every ৳100 wagered. However, this is a mathematical average over thousands of rounds; results in any single session can be completely different.
House Edge is the opposite of RTP — it represents how much the casino retains on average from each bet. If the RTP is 96%, the house edge is 4%. This is a normal part of casino operations and is present on all legitimate online platforms. A lower house edge is comparatively more favorable for the player over the long term.
The RTP range varies by game type. Slot games typically have an RTP between 92–98%. Table games like blackjack, when played with strategy, can have an RTP of nearly 99%. Roulette generally falls between 94–97%. In betting markets, the house edge is built in through the spread or vigorish.
Understanding RTP and house edge before playing is important because it helps you set realistic expectations. No game offers a guaranteed win — but choosing games with a lower house edge is an informed choice.
Typical RTP Ranges by Game Type
* These are general industry average ranges. Actual values depend on the specific game and provider.
