Ultra Treasure is bk888's most visually striking slot game. Five reels, cascading wilds, a free spin bonus round that can stack multipliers up to 50x, and a jackpot that resets at ৳500,000. If you've been looking for a slot that actually delivers on its promise, this is it.
Ultra Treasure is a five-reel, four-row video slot available exclusively on bk888. The game is built around an ancient treasure-hunting theme — think golden artefacts, glowing gemstones, and vault doors that crack open to reveal multiplied prizes. It's the kind of slot that looks great on a phone screen and plays even better when the bonus round triggers.
The base game runs on 40 fixed paylines, which means every spin has 40 ways to land a winning combination. Symbols pay left to right from the first reel, and the game includes both a Wild symbol and a Scatter. Three or more Scatters anywhere on the reels trigger the Free Spins feature — the centrepiece of Ultra Treasure and the reason most bk888 players keep coming back to it.
What separates Ultra Treasure from a standard slot is the Cascading Multiplier mechanic inside the free spins round. Every consecutive win during free spins increases a multiplier that starts at 1x and can climb all the way to 50x. A single free spin session with a hot streak can turn a modest stake into something genuinely significant. That's not marketing language — it's just how the maths works when the multiplier stacks.
bk888 also offers a Progressive Jackpot on Ultra Treasure that seeds at ৳500,000 and grows with every spin across all players. It can be triggered randomly on any spin regardless of the outcome, which means even a losing spin could end with a jackpot notification. That element of surprise is part of what makes Ultra Treasure one of the most-played slots on bk888.
Ultra Treasure uses eight main symbols plus a Wild and Scatter. Here's a quick breakdown of what each one means for your balance.
The Scatter symbol is the key to Ultra Treasure's biggest wins. Here's exactly what each Scatter count pays and triggers on bk888.
| Scatter Count | Free Spins Awarded | Starting Multiplier | Scatter Pay (x Total Bet) |
|---|---|---|---|
| 3 Scatters | 10 Free Spins | 1x | 2x |
| 4 Scatters | 15 Free Spins | 2x | 5x |
| 5 Scatters | 20 Free Spins | 5x | 20x |
| Retrigger (3+) | +10 Free Spins | Continues | — |
| Max Multiplier | — | 50x | — |
bk888 packed Ultra Treasure with mechanics that keep every session interesting. Here's what you'll encounter beyond the base game.
When a Wild lands on the reels, it expands to cover the entire column. After a win, symbols disappear and new ones cascade down — giving you multiple chances to win from a single spin without paying again.
Inside the free spins round, every consecutive winning cascade adds 1x to your multiplier. It starts at 1x and can reach 50x. A long cascade chain during free spins is where the biggest Ultra Treasure wins on bk888 come from.
The Ultra Treasure jackpot on bk888 seeds at ৳500,000 and grows continuously. It triggers randomly — any spin, any bet size. Every player contributes to the pool, and one lucky spin claims it all.
Landing 3 or more Scatters during the free spins round adds 10 more free spins to your remaining count. The multiplier keeps climbing through retriggered spins, so a retrigger late in the round can be extremely valuable.
Don't want to wait for Scatters to appear naturally? bk888's Ultra Treasure includes a Buy Feature option that lets you purchase direct access to the free spins round for 100x your current bet. Useful when you're feeling confident.
Ultra Treasure displays a live volatility indicator in the game UI. It shows how "hot" the current session is based on recent spin history — a useful guide for deciding whether to increase your bet or hold steady.

Ultra Treasure is a high-volatility slot. That means wins don't come on every spin — but when they do, they tend to be meaningful. Understanding this before you sit down is the most important thing any bk888 player can do.
High volatility slots like Ultra Treasure reward patience and proper bankroll management. A common mistake is betting too large relative to your total balance, then running out of funds before the free spins round triggers. A practical rule of thumb: your session bankroll should be at least 100x your chosen bet per spin. So if you're betting ৳50 per spin, you want at least ৳5,000 in your bk888 wallet for that session.
The Buy Feature is tempting, but use it selectively. At 100x your bet, it's a significant cost. It makes most sense when you have a healthy balance and want to guarantee a free spins session rather than grinding through base game spins. If your balance is running low, stick to organic play and let the Scatters come naturally.
During the free spins round, the multiplier resets to its starting value at the beginning of each new trigger. So if you retrigger free spins, the multiplier doesn't carry over — it starts fresh. This means the most valuable free spin sessions are the ones where you get a long cascade chain early, pushing the multiplier high before the spins run out.
Finally, keep an eye on the Progressive Jackpot meter displayed in the bk888 game interface. While the jackpot triggers randomly, some players prefer to play when the jackpot is significantly above its seed value — the logic being that a larger jackpot represents more accumulated value waiting to be won.
