Progressive PoolLive Side-Bet Jackpot

Top Batsman
Predict which batsman will score the most runs. This market is especially exciting in T20.

Types of Slot Games
The slot lobby on gb11 has various types of slots. Each plays differently — find out which one suits you.
Classic Slots
Old-school slots with three reels. Fewer symbols, simple rules — ideal for new players getting started. NetEnt's classic series is well known in this category.
Video Slots
Modern five-reel slots with themed graphics and animations. These feature the most free spins and bonus rounds. Pragmatic Play and PG Soft lead this category.
Jackpot Slots
A portion of every bet goes into a shared pool and the winner takes the entire pool. Microgaming's progressive network is known for this type of slot.
Megaways Slots
The number of symbols on each reel changes with every spin, creating thousands of ways to win. Pragmatic Play's Gates of Olympus uses this mechanic.
Cascading Reels
Winning symbols disappear and new symbols drop from above — giving you multiple chances to win from a single spin. Pragmatic Play's Sweet Bonanza is played in this style.
Cluster Pays
You win when a set number of matching symbols appear side by side — no paylines involved. Pragmatic Play's Sugar Rush is a great example of this mechanic.
RTP and House Edge Explained
RTP, or Return to Player, is the percentage a game returns to players over the long term. For example, if a game has an RTP of 96%, it theoretically returns ৳96 for every ৳100 wagered. However, this is an average across millions of spins — getting more or less in a single session is normal.
The typical RTP range varies by game category. Slot games generally fall between 92–98%, card games like blackjack can reach close to 99% with the right strategy, and European roulette sits at around 97%.
House edge is the flip side of RTP — it is what the casino keeps over the long term. The higher the RTP, the lower the house edge. Smart players always choose high-RTP games and stay within their budget — that is the key to long-term enjoyment.
Local Card Games
Card games popular in Bangladesh and South Asia are available on gb11. Play by familiar rules in a new setting.
Teen Patti
Players compete against each other or against a live dealer with three cards each. The best three-card combination wins the prize. Tip for beginners: start with small bets and watch the patterns of other players. JILI's TeenPatti Joker and Teen Patti 20-20 are especially popular.
Live Dealer & MultiplayerAndar Bahar
The dealer reveals a middle card, and the player bets on whether a card of the same value will land Andar (inside) or Bahar (outside). Simple rules, fast results. Statistically, betting on Andar at the start is slightly advantageous. Can be played with a live dealer.
Live DealerCallbreak
A trick-taking card game for four players where you must declare your hand before each round. JILI's Callbreak Quick lets you play against multiple people. Tip for beginners: bid conservatively rather than relying too heavily on your hand.
MultiplayerLudo & Rummy
Familiar board and card games are now available online. In JILI's Ludo Quick, roll the dice and move your pieces; in Pool Rummy, form sets to lower your points. Play against other players in real time.
MultiplayerFishing & Arcade Games
Fishing games are shooting-style games where you hunt fish at the bottom of the ocean and earn rewards based on the size and rarity of the fish. Each shot has its own cost, so strategic shooting is essential.
Mega Fishing
In JILI's Mega Fishing, hunting large boss fish earns huge multipliers. Increasing the cannon level makes it easier to catch bigger fish.
Bombing Fishing
Hunt multiple fish at once using explosives. In this JILI game, group attacks give you the chance to earn greater rewards.
Dinosaur Tycoon
Hunt dinosaurs in this JILI arcade game — from small to massive dinosaurs, each with different multipliers.
Ocean King Jackpot
Face the king of the sea and trigger the jackpot. In this JILI game, special weapons can be used against the boss fish.
Manage your cost per shot in fishing games — don't waste a big cannon on small fish. Wait for boss fish and increase the cannon level gradually.
How to Read Odds
Understanding odds is very important in online betting. The simplest format is decimal odds, which is used on all major betting sites in Bangladesh.
Example: Decimal Odds
৳500 bet × 1.80 = ৳900 total return
Profit: ৳400 (excluding the original bet)
To find the probability from decimal odds, divide 1 by the odds: 1÷1.80 = 55.6% — this is the implied probability. It means the market believes there is roughly a 56% chance of this event occurring.
| Format | Example | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳180 total return for every ৳100 bet |
| Fractional | 4/5 | ৳4 profit for every ৳5 bet |
| American | -125 | ৳100 profit on a ৳125 bet (favorite) |
Bankroll Management Guide
Playing responsibly means enjoying more time at the game. Following the principles below will improve your gaming experience and help you avoid unnecessary losses.
Set a budget first
Decide how much money you will spend before you start playing. This amount should only be money that, if lost, will not affect your daily life — not rent, food, or emergency expenses.
Divide into sessions
Split your total budget across multiple sessions. For example, if your budget is ৳3,000, set aside ৳600–৳700 per session. This reduces the chance of losing your entire budget in one bad session.
The 1–5% per bet rule
A single bet should be at most 1–5% of your session bankroll. If you have ৳500 for a session, place ৳5 to ৳25 per bet. Following this rule lets you play for longer.
Stop at the right time after winning
Set a target after a win and stop when you reach it. Many people lose their winnings by trying to win even more. Enjoy a win for what it is.
Set a loss limit
Stop playing if you lose 50% of your session. Placing larger bets to recover losses ("chasing losses") almost always leads to even greater losses. Wait until the next session.
Keep a record of your play: Tracking how much you have won, how much you have lost, and which games you have spent the most time on gives you a clear picture of your playing habits and helps you make better decisions in the future.
