Live Casino Games ListHow Weekly Cashback Works
Each week, your net loss is calculated by subtracting your total winnings from your total losses. A set percentage of that net loss is returned to your account as cashback, based on your VIP tier.
Calculation Example (Gold Tier)
Net loss for the week: ৳20,000
Gold tier cashback rate: 0.9%
৳20,000 × 0.9% = ৳180 cashback
Cashback reduces losses to some extent, but it is not a guaranteed way to win.

Jackpot Games Collection
A portion of every bet goes into the pool — and when someone wins it, the jackpot resets and starts growing again from zero.
Progressive Jackpot Slots
The jackpot pool grows with every spin. A specific combination or entering a bonus game gives you the chance to win the full jackpot.
Fishing Game Jackpot
In fishing games from JILI and JDB, catching a special large fish or boss character triggers the jackpot — the higher the multiplier, the bigger the prize.
Live Casino Side-Bet Jackpot
On some live tables from Evolution and Ezugi, placing a side bet gives you a chance to win a large prize — the jackpot pool is built from all players' bets.

With Big Time Gaming's Megaways mechanic, the number of paylines changes every spin, and multipliers accumulate during free spins.

Betting Exchange — What Are Back and Lay?
On a standard sportsbook, you bet against the site. On an exchange, you bet against other players — odds are determined by market supply and demand. The exchange takes a small commission from each winning bet.
A Back bet means betting in favour of a team winning. A Lay bet means betting against that team winning — you act in the role of the bookmaker.
| Back Bet | Lay Bet |
|---|---|
| Betting in favour of a team winning | Betting against a team winning |
| Profit if the team wins | Profit if the team does not win |
| Risk of losing the stake | Risk of losing the liability amount |
| Familiar betting style | Works like a bookmaker |
Calculation Example (decimal 2.00)
BACK: You bet ৳500 on team A to win.
- ৳500 profit before commission if team A wins
- You lose ৳500 if team A does not win
LAY: You lay ৳500 stake against team A winning.
- Liability: ৳500 × 1.00 = ৳500
- If Team A does not win, ৳500 profit before commission
- If Team A wins, ৳500 must be paid out
Team A and Team B are for illustration only — this is not actual odds or a guarantee of winning.
Slot RTP and Volatility Basics
RTP (Return to Player) is a long-term average — calculated over millions of spins. It does not guarantee how much you will get back in a single session. Slot RTP typically falls around 94–97%.
For example, PG Soft's Fortune Mouse has a maximum RTP of 96.96%, and Pragmatic Play's Gates of Olympus has a maximum RTP of 96.50%.
Low Volatility
Small wins come frequently. Your budget lasts longer, but the chance of a large one-time win is low.
Medium Volatility
There is a balance between small and large wins. A good starting point for new players.
High Volatility
Wins may not come for a long time, but when they do, they are large. Suited for a bigger budget.
How Does a Progressive Jackpot Grow?
A small portion of each bet is added to the jackpot pool. The more people play, the faster the pool grows. The entire pool can be won at once by hitting a specific bonus or symbol combination.
Choose a Slot Based on Your Budget and Style
If you want to play longer on a smaller budget, go for low volatility slots. If you can take more risk in pursuit of a large win, choose high volatility. In either case, stay within a set budget.
In responsible gaming, taking breaks and setting limits are equally important.
