About the Game
Ultra Treasure is a five-reel, three-row video slot available exclusively through koko500 for Bangladesh players. The theme pulls from classic treasure hunting imagery — golden chests, ancient coins, jade dragons, and glowing gemstones — but the mechanics are anything but old-fashioned. Under the surface, Ultra Treasure runs a four-tier progressive jackpot system alongside a free spins round and a chest bonus feature that can stack multipliers across multiple paylines simultaneously.
What separates Ultra Treasure from the dozens of treasure-themed slots you'll find on other platforms is how the jackpot system is integrated into normal gameplay. You don't need to hit a separate bonus screen to trigger the jackpot — the Grand Jackpot symbol can land on the reels during any spin, including free spins. That means every single spin carries a genuine shot at the top prize, not just the spins where you've activated a side game.
For koko500 players in Bangladesh, Ultra Treasure has become one of the most-played slots on the platform for a straightforward reason: the free spins round is genuinely rewarding. When you land three or more Scatter symbols, you get a minimum of 10 free spins with all wins multiplied. The round can retrigger up to five times, meaning a single Scatter landing can turn into 50 free spins if the reels cooperate. That kind of upside is rare in slots at this price point.
Jackpot System
Ultra Treasure on koko500 runs a live four-tier jackpot. Each tier seeds from player wagers and grows continuously. Any tier can be triggered on any spin — no bonus game required.
Unlike many jackpot slots that require a maximum bet to qualify, Ultra Treasure on koko500 keeps all four jackpot tiers open to every bet size. The probability of triggering each tier scales with your bet — higher stakes increase your chance of hitting the Grand — but even a ৳20 minimum spin carries a live shot at all four tiers. This is a deliberate design choice that makes Ultra Treasure accessible to the full range of koko500 players, from casual spinners to high-stakes regulars.
The jackpot trigger is separate from the payline outcome. You can land a jackpot on a spin that also produces a regular win, a free spins trigger, or even a losing payline result. The two systems run in parallel, which means jackpot wins are genuinely additive — they don't replace your spin result, they add to it.
All jackpot wins on koko500 are credited to your balance instantly and can be withdrawn to bKash or Nagad without any additional wagering requirement attached to the jackpot amount itself.

Key Features
Land three Golden Chest symbols on reels 1, 3, and 5 to open the chest bonus. Pick from a grid of chests to reveal multipliers that apply directly to your current bet.
Three or more Scatters award 10 free spins with a 2× multiplier. Landing Scatters during free spins adds 10 more, up to a maximum of 50 free spins in a single round.
The Wild symbol expands to fill its entire reel when it contributes to a winning combination. On free spins, all Wilds are sticky — they stay in place for the remainder of the round.
Ultra Treasure pays left-to-right and right-to-left across all 243 ways. Every spin evaluates both directions, effectively doubling the number of winning combinations available.
Activate Bet Multiplier Mode to increase your stake by 25% in exchange for a boosted jackpot trigger rate. Useful for players targeting the Major or Grand jackpot specifically.
Ultra Treasure is fully optimised for the koko500 mobile app and mobile browser. The reel layout, bonus screens, and jackpot animations all scale cleanly to any screen size.
Game Specifications
Playing Smart
Ultra Treasure is a high-volatility slot, which means the session experience is different from a medium-variance game. You'll go through stretches where the reels feel cold — regular wins are smaller and less frequent — and then a free spins round or a jackpot trigger will arrive and reshape your balance in a single sequence. Understanding this rhythm is the most important thing you can do before you start spinning on koko500.
On a high-volatility slot like Ultra Treasure, a session budget of 100–150 spins at your chosen stake gives you a realistic chance of hitting the free spins round at least once. Shorter sessions on high stakes often end before the variance works in your favour. Consider dropping your bet size and extending your spin count instead.
The 25% stake increase in Bet Multiplier Mode is worth it if your primary goal is the Major or Grand jackpot. If you're playing for the free spins round or the chest bonus, the standard bet mode is more efficient — you get more spins for the same budget, and the bonus features trigger based on symbol frequency, not stake size.
When the free spins round triggers on koko500, the sticky Wild mechanic means the round builds momentum as it progresses. Wilds that land early stay on the reels for all remaining spins. The best outcomes from Ultra Treasure's free spins round almost always come from the later spins in the sequence, when multiple sticky Wilds are in play simultaneously.
koko500 regularly runs slot-specific promotions that include Ultra Treasure. Deposit bonuses, free spin credits, and cashback offers all apply to Ultra Treasure wagers. Check the promotions section before your session — playing with bonus funds on a high-volatility slot like this one extends your session significantly and gives the variance more room to work.
