The card games you know from home are now online — with the dealer right on your screen.
Teen Patti
Played with three cards — the best hand wins. Each round, players bet against the dealer or against each other. Start with small bets to get a feel for hand rankings.
💡 Beginner tip: Play 'seen' (looking at your cards) for the first few rounds, not 'blind'.
Played against a live dealer.
Andar Bahar
One card is placed face-up in the middle of the table, then cards are dealt alternately to two sides (Andar and Bahar). Bet on the side where a matching card appears first to win. Simple rules, fast rounds.
💡 Beginner tip: Look at the middle card's value and pick either side.
Played against a live dealer.
Callbreak
In this four-player card game, you must declare how many tricks you will take each round. Spades are the strongest or 'trump' suit. Taking fewer tricks than declared costs you points. You play against the other players.
💡 Beginner tip: If you have more than four spades in hand, make a high declaration.
Played against other players.
Ludo Quick
The Ludo you know, now in a fast online format — race to move your pieces out and bring them home before your opponents. The dice roll is random, but choosing which piece to move is where strategy comes in.
💡 Beginner tip: Move one piece safely ahead while getting another out of home.

How Weekly Cashback Works
Even in a losing week, a portion comes back — depending on your VIP level.
What Is Cashback?
Weekly cashback is a set percentage returned on your total net loss for that week — calculated as (total losses — total wins) × cashback rate. The rate depends on your current VIP level.
Calculation Example
Level: Gold
Net loss for that week: ৳20,000
Cashback rate: 0.5%
Cashback: ৳20,000 × 0.5% = ৳100
Cashback softens losses slightly — it is not a method for winning or a guarantee that losses will be recovered.
Betting Terms Explained Simply
New or experienced — knowing these terms makes following the action much easier.
Asian Handicap
The market is levelled by giving the weaker team a virtual goal or run head start. Eliminating the draw often improves the odds, and there is also the benefit of a push refund.
Over/Under (Totals)
Bet on whether the total runs or goals in a match will be above or below a set number. You only need to estimate the total score — no need to judge which team is in form.
Odds Formats
Decimal (3.00), Fractional (2/1) and American (+200) — all three express the same probability. A ৳200 bet at decimal 3.00 means a total return of ৳600.
RTP (Return to Player)
The percentage of each ৳100 wagered that a slot or game returns on average over the long term. An RTP of 96% means an average of ৳96 comes back over time — but any individual session can vary.
House Edge
The mathematical advantage a casino holds in every game is called the house edge. An RTP of 96% means a house edge of 4% — the contest is not even, but large short-term wins are possible.
Wagering Requirement
The condition specifying how many times a bonus must be wagered before it can be withdrawn. For the 77abc calm welcome bonus, this is 25 times the bonus amount.
Live Dealer Casino
Play baccarat, roulette or blackjack with a dealer broadcast live from a real studio. Get the feel of a real table from Dhaka at any time, from home.
Slot Volatility
High volatility means less frequent but larger prizes; low volatility means frequent smaller wins. With a smaller budget, low volatility is safer.
Progressive Jackpot
A portion of bets from many players across the same network pools together to build a large jackpot. When someone wins, the pool resets to zero.
Cashback
A percentage of net losses over a set period returned to the player. At 77abc calm this is weekly, and the rate depends on your VIP level.
Multi Bet (Accumulator)
Combining selections from several matches multiplies the odds, making potential returns much larger. However, if even one selection is wrong, the entire bet is lost.
In-Play / Live Betting
Place bets in real time while a match is in progress, at constantly changing odds. In a BPL or T20 match, odds shift quickly after a wicket — that moment is the opportunity.
The Right Time to Start Playing Is Now
Open an account, make your first deposit and claim your bonus. Cricket betting, slots or live baccarat — the choice is entirely yours.

Ask Yourself Once
Gaming is for enjoyment. Ask yourself these questions from time to time — if the answer to even one is 'yes', it's time to be careful.
Am I spending more than my set budget?
When I lose, do I bet more to try to recover my losses?
Am I playing with money borrowed from family or friends?
Is gaming taking time away from my family or work?
When I try to stop playing, do I feel restless or irritable?
Am I hiding my losses from family or close ones?
If the answer to even one of these is 'yes' — use the deposit limit, time-out, or self-exclusion options on the site. Talk to a family member or a trusted friend. For more information, read the responsible gaming guidelines. This site is strictly for those aged 21 and above.
Back & Lay: How the Exchange is Different
With a regular bookmaker, you bet against the house. On an exchange, you bet against other players.
Back vs Lay — a quick comparison
| Back Bet | Lay Bet |
|---|---|
| Betting that a team will win | Betting that a team will not win |
| Like a regular bookmaker | You act as the bookmaker |
| Maximum loss: the stake | Liability: (Odds - 1) × stake amount |
| Odds available in the market | Odds are set by other players |
| Commission is usually on winnings | Commission is usually on winnings |
Example — exchange odds 2.50:
Back Team A — ৳1,000 stake: If Team A wins, profit of ৳1,500 before commission; if not, you lose ৳1,000.
Lay Team A — ৳1,000 Backer's stake: Liability ৳1,500 (৳1,000 × 1.50); if Team A does not win, profit of ৳1,000 before commission; if Team A wins, you pay ৳1,500.
Team A and Team B are examples only — not live odds or a guarantee of any outcome.
Exchange vs Regular Bookmaker
With a regular bookmaker, the platform sets the odds. On an exchange, odds are formed by the supply and demand of other players — so you can sometimes get a better price.
Commission on the exchange is usually charged on winnings; no specific percentage is stated here — it varies by platform.
Lay betting is an additional strategic option — you can bet not just on a 'win' but also on a 'loss'. However, understand how liability is calculated before you start.
