Real DealersCricket Format Guide
Understanding the formats is important for cricket-loving bettors in Bangladesh. Betting markets vary across different formats.
T20
Each team plays 20 overs and the match usually wraps up in 3 hours. Live betting, session bets and exotic markets like Man of the Match are available. BPL and the T20 World Cup are played in this format.
BPL • T20 WCODI (One-Day)
Each team plays 50 overs and the match lasts 7 to 8 hours. Markets like innings runs, top scorer and number of wickets are most popular. The ICC Champions Trophy and World Cup use this format.
ICC • World CupTest
A 5-day match with two innings per side. The possibility of a draw means 3-way betting markets (win/loss/draw) apply. There are more opportunities for strategic betting and session betting.
3-Way MarketThe Hundred
Each team faces 100 balls, making this new format — played in England — extremely fast-paced. With a limited number of balls, every delivery matters in betting.
England LeaguePopular Leagues
BPL (Bangladesh Premier League) — held in Dhaka and across the country. IPL — India's biggest T20 league and a favourite among Bangladeshi fans. BBL — the Australian Big Bash League. PSL — the Pakistan Super League. Bangladesh Tigers are at the heart of supporters' passion across all formats.
Football Betting Guide
Football fans in Bangladesh are most excited about the Premier League, La Liga, UEFA Champions League and FIFA World Cup qualifiers. All of these leagues are available for betting on 5666et.
1X2 Bet
Back a home win, a draw or an away win — pick any one of the three. The simplest and most popular market.
Double Chance
Cover two outcomes at once (for example, home win or draw). Lower risk, but odds are lower too.
Over/Under Goals
Bet on whether the total goals in a match will be over or under 2.5.
Both Teams to Score
Will both teams score at least one goal — yes or no. A straightforward bet.
Asian Handicap
The weaker team is given a virtual advantage to level the contest. Popular for higher odds.
Live Bet
Place bets in real time while the match is in progress. Many big matches kick off between 1 and 3 AM Bangladesh time (BST).
Local Card Games
Teen Patti
Each player receives 3 cards and the player with the best hand wins. This familiar South Asian game can now be played online with a live dealer. Start with small stakes and learn to read the other players.
Live Dealer vs PlayersAndar Bahar
One card is placed face-up in the middle of the table and players place their bets — will the next matching card fall on the left (Andar) or the right (Bahar)? Simple and fast, it is played against a single live dealer. For beginners, place small bets in the first round.
Live DealerCallbreak
52 cards are dealt among 4 players and each player bids how many tricks they will win. Spades are always trump. A correct bid earns points; an incorrect one deducts them — so bidding accurately is the key strategy.
MultiplayerLudo / Rummy
The familiar Ludo can now be played online for real money against other players. In Rummy, the goal is to form sets and runs by matching cards. Tip for beginners: in Rummy, discard low-value cards early to lighten your hand.
MultiplayerFishing and Arcade Games
Fish-shooting games are growing in popularity in Bangladesh day by day. In JILI's Mega Fishing, All-star Fishing and Ocean King Jackpot, you aim and shoot at fish swimming across the screen — catching a fish rewards you according to its multiplier.
Cannon Levels and Fish Multipliers
A more powerful cannon costs more per shot but gives you a better chance of catching big fish. Small fish carry lower multipliers, while boss fish and special mobs offer the biggest winning opportunities.
Popular Arcade Game Types
- Fishing Games: Live multiplayer fish-shooting where boss waves offer the biggest prizes.
- Dice Games: Simple mechanics, fast rounds and a variety of betting options.
- Coin Pusher: Drop coins to push prizes off the board.
- Crash Games: Games like Spribe Aviator where cashing out at the right moment is the skill.
Tips for Managing Shot Costs
Start at the lowest cannon level and only fire big shots when a boss fish appears. Set a budget for each session and do not go over it.

Betting Glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
The percentage of total wagers that a game returns to players over the long term. For example, 96% RTP means an average of ৳96 is returned for every ৳100 wagered.
House Edge
The casino's long-term mathematical advantage. A higher house edge means the casino keeps more; a lower one means better chances for players.
Wagering Requirement
The number of times a bonus amount must be wagered before it can be withdrawn. 20x means you need to place a total of ৳20,000 in bets for a ৳1,000 bonus.
Odds
The ratio of the probability of an event occurring to the potential reward. The higher the odds, the lower the chance of winning, but the larger the potential reward.
Parlay / Accumulator
Combining multiple bets together, with the payout multiplying for each win. Losing a single leg means losing the entire bet.
Live Bet
Placing bets in real time while a game is in progress. Odds change quickly, so fast decision-making is essential.

The option to withdraw part of your bet before a match or event ends. Used to reduce risk.
Bankroll
The total amount of money set aside for gaming. Proper bankroll management helps sustain play over the long term.
Volatility

The opportunity to spin for free in a slot game. Usually awarded when a bonus is triggered or special symbols are activated.
Stake
The amount of money you are wagering in a single round or event. Always set your stake within your means.
