Crash Game — Fast-Paced Excitement
Crash games, and Aviator in particular, have gained widespread popularity around the world over the past few years. At the start of each round a multiplier rises from zero — from ×1.00 slowly up to ×2, ×5, sometimes even higher.
The player must cash out before the game "crashes". The longer you wait, the higher the multiplier climbs — but if it crashes, you lose that round's bet.
With the Auto Cash Out feature you can set a specific multiplier in advance — when that multiplier is reached, your bet will cash out automatically.
Each round ends in just a few seconds to a minute or two, so the game is fast-paced and demands attention. Before playing, set a stop limit for yourself — decide at which multiplier you will cash out and how many rounds you will play.

Bonus Terms in Plain Language
Understand the terms before claiming a bonus — no hidden surprises.
| Bonus Type | Rate | Maximum Bonus | Wagering |
|---|---|---|---|
| Welcome Bonus (First Deposit) | 150% | ৳20,000 | 10x (on the bonus amount) |
| VIP Weekly Cashback | 0.3% – 1.0% | Based on tier | No wagering on cashback |
Wagering Requirement
You must place a certain amount of bets before withdrawing winnings from a bonus. This is calculated only on the bonus amount — not on your deposit. Example: ৳1,500 bonus × 10 = you need to place ৳15,000 in bets before the bonus winnings can be withdrawn.
Game Contribution
Not all games may contribute equally to wagering. Slot games typically contribute in full, but the contribution rate for table games and live casino may vary.
Maximum Bet While a Bonus Is Active
There is a specific maximum bet limit per round while a bonus is active. This is clearly stated in the terms and conditions — placing bets above the limit may result in the bonus being cancelled.
Bonus Expiry and Cash-Out Limit
Each bonus has a set expiry period — if wagering is not completed within that time, the bonus may be cancelled. In addition, some bonuses may have a maximum cash-out limit.
Bankroll Management Guide
The most important part of enjoying online gaming responsibly is bankroll management. This means managing your gaming budget in a planned way — not just to win, but to maintain an enjoyable experience over the long term.
- Set a gaming budget: Allocate a fixed amount each month specifically for gaming. This amount should be something that, if lost, will not affect your daily life.
- Divide into sessions: Split your monthly budget across several sessions. Do not spend the entire budget in one session. Smaller sessions let you enjoy more time overall.
- The 1–5% rule per bet: Keep each bet between 1% and a maximum of 5% of your total session bankroll. This way, a bad run will not ruin the entire session.
- Take a break after winning: When you reach a set target, consider it time to end the session. Chasing more out of greed can cause you to lose earlier gains.
- Stop after a loss: Set a specific loss limit in advance. If you reach that limit, stop playing for the day. Reckless betting to recover losses is never the answer.
- Keep track of your play: In a simple note, record the deposit, wins and losses, and time for each session. This habit will help you recognise patterns and make better decisions.
Remember, online casino is a form of entertainment — it is wise not to treat it as a source of income.

Betting Terms / Glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
RTP is the theoretical rate at which a game returns money to players from total bets placed over the long term. For example, a 96% RTP means that for every ৳100 wagered, there is a theoretical average of ৳96 returned.
House Edge
House Edge is the mathematical advantage held by the casino — a small percentage of every bet in each game is retained in favour of the casino over the long term. It is the other side of RTP.
Wager / Wagering
Wager means placing a bet. Wagering requirement refers to the condition of how much you need to bet before bonus funds can be withdrawn.
Stake
Stake is the amount placed on a specific bet. The money you put at risk each round is your stake.
Odds
Odds are the numerical expression of the probability of an event. Higher odds mean a greater reward if you win on a less likely outcome.
Accumulator / Parlay
Multiple bets are combined into a single bet where all conditions must be met to win. The risk is higher, but the reward multiplies.
Live Bet
The ability to place bets in real time while a game is in progress. Odds change as the match situation changes, and decisions must be made quickly.
Cash Out
Cash Out is the facility to settle a bet before the game or match ends. It is used to secure a partial profit or reduce a potential loss.
Volatility
The volatility of a slot game refers to how often and how large the rewards are. High volatility = fewer but bigger wins; low volatility = more frequent but smaller wins.
Free Spin
A Free Spin is the opportunity to spin the reels of a slot game at no cost. It is available as a bonus feature or as part of a promotion.
Bankroll
Bankroll is the total funds set aside for gaming. Proper bankroll management ensures an enjoyable experience over the long term.
