Bonus Terms in Plain Language
Knowing the bonus terms makes playing much easier. Everything is explained in plain language below.

|---|---|---|---|
| First Deposit Welcome Bonus | 150% | ৳10,000 | 15x the bonus amount |

What Is a Wagering Requirement?
To withdraw winnings from a bonus, you must first place a specified amount in bets. This is calculated on the bonus amount only, not on the deposit plus bonus.
Example: ৳1,500 bonus × 15 = ৳22,500 in bets required before bonus winnings can be withdrawn.
Game Contribution
Not all games contribute equally toward wagering. Slots generally contribute the most. Live table games or sports betting may contribute less. Check the terms before accepting a bonus.
Maximum Bet While Bonus Is Active
Placing a bet above a certain limit per round while a bonus is active may result in the bonus being cancelled. Check the exact limit in the bonus section of your account.
Bonus Expiry and Maximum Cashout
Each bonus has a set expiry date. If the wagering requirement is not met before expiry, the bonus is cancelled. There is also a maximum amount that can be withdrawn from bonus winnings. See the terms for details.

Join NowAccount Verification Process
The KYC (Know Your Customer) process keeps your account secure and ensures safe transactions. It is an internationally recognised security procedure.
Without identity verification, there is a risk of fraud and unauthorised transactions. KYC protects your account from being used by others and makes withdrawals safer.
Typically required: National ID (NID), proof of address (utility bill or bank statement), and selfie verification. All images must be clear and legible.
Verification is usually completed quickly. Providing accurate and clear documents speeds up the process. The support team is available to help with any issues.
Once verification is complete, all account features are activated — such as large withdrawals, participation in the VIP program, and transactions with the highest level of security.

Crash Games — Fast-Paced Thrills
Crash games like Aviator and JetX are currently the most talked-about category in online gaming. Each round lasts only a few seconds to a few minutes, making them extremely fast-moving.
How Does a Round Work?
Set your bet amount before the plane (or rocket) takes off. The number (multiplier) keeps rising — press the cash out button before it crashes. If you cash out in time, your bet is multiplied by that multiplier and returned to you.
Auto Cash Out
There is a setting to cash out automatically at a chosen multiplier. No need to press the button manually — the game collects your winnings at that point on its own.
🛑 Set a Stop Limit Before You Play
Rounds in crash games end quickly, which can lead to placing more bets than intended. Set a stop limit before you start playing and stop when you reach that limit. Play responsibly.
Local Card Games — Familiar Games, New Thrills
Teen Patti, Andar Bahar, Callbreak and Ludo / Rummy — these familiar games are now available online. Play against a live dealer or other players.
Teen Patti
This classic three-card game starts each round with an ante. The player with the strongest hand wins. Starting Tip: Begin with small bets and read the other players' patterns. Available in both live dealer and multiplayer formats.
Andar Bahar
A card is revealed and you bet on whether the next card of the same value will fall on the 'Andar' (inside) or 'Bahar' (outside) side. Starting Tip: The rules are simple, making it ideal for beginners. Play with a live dealer.
Callbreak
A four-player trick-taking card game widely popular in Bangladesh and India. Each round requires winning hands according to the 'call'. Starting Tip: Understanding how to use spades makes the game much easier. Always played against other players.
Ludo / Rummy
JILI's Ludo Quick and Pool Rummy are digital versions of familiar board and card games. Starting Tip: In Rummy, learning the strategy for building sequences and sets is the key. Always played against other real players.
How to Read Odds?
Understanding odds is the most important skill in betting. Here are three common formats explained in simple terms.
Decimal Odds (Easiest)
In decimal format, the total return is shown directly.
৳500 × 1.80 odds = ৳900 total return
(Profit: ৳400, original bet: ৳500)
Fractional Odds (British)
In the British method, odds are shown as fractions.
4/5 odds means ৳4 profit on a ৳5 bet.
In decimal: 4/5 + 1 = 1.80
American Odds (Money Line)
The American method uses + and – signs.
-125 means ৳100 profit on a ৳125 bet.
+200 means ৳200 profit on a ৳100 bet.
What is Implied Probability?
You can calculate the probability of an event from its odds. The implied probability of 1.80 decimal odds is 1 ÷ 1.80 = 55.6%. This means the bookmaker believes this team will win roughly 56% of the time. If you think the probability is higher, it could be a good bet.
