Ultra Treasure is one of the most played slots on CV 666, and it's easy to see why. Four progressive jackpots, a free spins round that can multiply your winnings up to 50x, and a treasure chest bonus that drops randomly on any spin. Deposit via bKash and start spinning in under two minutes.
Ultra Treasure isn't just another slot on CV 666 — it's one of the platform's flagship titles, and it's been that way since the day it launched. The game runs on a 5-reel, 243-ways engine, which means every spin has hundreds of potential winning combinations without you needing to worry about which paylines to activate. Everything is always in play.
What really sets it apart is the four-tier progressive jackpot system. Every bet placed on Ultra Treasure across all CV 666 players contributes a small percentage to the jackpot pool, which means the Grand Jackpot can grow to several million taka before it drops. The Mini and Minor jackpots hit far more frequently, so even if you're not chasing the top prize, there's a realistic chance of landing a jackpot win on any given session.
Understanding the mechanics helps you get more out of every session. Here's a breakdown of the core features inside Ultra Treasure.
Ultra Treasure uses a 5x3 reel grid with 243 ways to win active on every spin. Wins are formed by matching symbols on adjacent reels from left to right, regardless of their exact row position. This format gives you far more winning opportunities per spin than a traditional fixed-payline slot.
Every spin on Ultra Treasure at CV 666 contributes to four separate jackpot pools. The Mini jackpot hits frequently and pays smaller amounts. The Minor and Major jackpots hit less often but pay significantly more. The Grand Jackpot is the top prize — it can reach millions of taka and is won randomly, meaning any spin could trigger it regardless of your bet size.
Landing 3, 4 or 5 scatter symbols anywhere on the reels triggers the Ultra Treasure free spins round. Three scatters award 10 free spins, four award 15, and five award 20. During free spins, a multiplier trail activates — each consecutive win increases the multiplier by one step, up to a maximum of 50x your base bet.
The Treasure Chest is a random bonus feature that can appear after any spin on CV 666. When it triggers, a chest opens to reveal one of several prizes: an instant cash award, a multiplier applied to your last win, a direct entry into the jackpot wheel, or a set of bonus free spins. It cannot be predicted or triggered deliberately — it's purely random.
The Ultra Treasure wild symbol substitutes for all regular symbols to complete winning combinations. It appears on reels 2, 3, 4 and 5. During the free spins round, wilds become sticky — they stay in place for the remainder of the free spins once they land, significantly increasing the chance of consecutive wins and multiplier progression.
The jackpot wheel is a separate mini-game that can be triggered either through the Treasure Chest bonus or by landing the special jackpot scatter on all five reels simultaneously. Once on the wheel, you spin to determine which of the four jackpots you win. Every segment on the wheel guarantees a jackpot prize — the question is just which tier.
Payouts shown are for a 5-symbol win at the minimum bet of ৳10 per spin. Higher bets scale proportionally.

Ultra Treasure's jackpot can be triggered at any bet level — you don't need to bet the maximum to qualify for the Grand Jackpot. Starting at ৳10 per spin on CV 666 gives you more spins per session, which means more chances to trigger the free spins round and the Treasure Chest bonus.
The free spins round is where the biggest non-jackpot wins happen in Ultra Treasure. The sticky wilds and multiplier trail can combine to produce wins of 100x or more your bet. When you trigger free spins on CV 666, let them play out fully rather than using any early cash-out option — the multiplier builds as consecutive wins stack up.

The platform's responsible gaming tools include a session time reminder that alerts you when you've been playing for a set period — a simple feature that makes a real difference.
CV 666 keeps a full history of your bets and results in your account dashboard.

It also helps you spot whether your bet sizing is working for your bankroll.
Ultra Treasure has built a loyal following among CV 666 players in Bangladesh, and it's not hard to understand why. In a market where most online slots offer a fixed maximum win and a straightforward bonus round, Ultra Treasure does something different — it layers multiple win paths on top of each other so that every spin carries genuine excitement. You might land a solid base game win, trigger the free spins round, pick up a Treasure Chest bonus, and still be in with a chance of hitting the jackpot wheel, all within the same session.
For Bangladesh players specifically, the appeal goes beyond the game mechanics. CV 666 has built its platform around the payment methods and habits that Bangladeshi players actually use. bKash is the dominant mobile payment service in the country, and CV 666 treats it as a first-class deposit and withdrawal option — not an afterthought. Deposits are instant, withdrawals are processed within 15 minutes, and there are no hidden fees on either side. When you win on Ultra Treasure, getting that money into your bKash wallet is genuinely fast and straightforward.
The 96.8% RTP on Ultra Treasure is worth dwelling on for a moment. Return-to-player percentage is a theoretical figure calculated over millions of spins, so it doesn't tell you what will happen in any individual session. What it does tell you is that Ultra Treasure is designed to return a higher proportion of bets to players over time compared to many other jackpot slots. For context, many progressive jackpot slots sit at 94% or 95% RTP — Ultra Treasure's 96.8% is meaningfully better, and it's one of the reasons CV 666 chose to feature it so prominently in the slots lobby.
The free spins round deserves special attention because it's where most of the game's biggest non-jackpot wins are generated. When you trigger it with five scatter symbols — the maximum — you start with 20 free spins and a multiplier trail that begins at 1x. Each consecutive winning spin moves the multiplier up one step. If you can string together a run of wins during the free spins round, the multiplier can reach 50x, which applied to a solid base win can produce a payout that dwarfs anything the base game delivers on its own. The sticky wilds that appear during free spins are the key to making this happen — each wild that lands stays in place for the rest of the round, progressively filling the reels and making consecutive wins more likely.
The Treasure Chest bonus is the feature that keeps Ultra Treasure feeling unpredictable in the best possible way. Because it can drop on any spin — including spins that produce no base game win — it means there's never a truly dead spin in Ultra Treasure. Even a spin that lands no matching symbols might still trigger the chest and award an instant cash prize or a jackpot wheel entry. This random element is what separates Ultra Treasure from more predictable slot formats and keeps experienced players coming back to CV 666 for session after session.
CV 666 also runs regular promotions that specifically include Ultra Treasure. These range from reload bonuses that give existing players extra credit on their deposits, to free spin promotions that award a set number of spins on Ultra Treasure at no cost. Keeping an eye on the CV 666 promotions page is worthwhile — these offers can significantly extend your playing time and give you additional chances to hit the jackpot without increasing your own spending.
One thing that players new to progressive jackpot slots sometimes wonder about is whether the jackpot is genuinely random or whether there's a pattern to when it drops. The honest answer is that Ultra Treasure's jackpot system uses a certified random number generator, which means each spin is completely independent of every other spin. The jackpot doesn't become "due" after a long period without dropping — the probability of triggering the jackpot wheel is the same on every spin, regardless of how long it's been since the last jackpot was won. This is verified by the independent testing laboratory that audits CV 666's games, and the certification is available on the platform's licensing page.
Whether you're a regular CV 666 player looking for a new slot to add to your rotation, or someone who's never played an online slot before and wants to start with one of the best options available in Bangladesh, Ultra Treasure is a strong choice. The combination of a high RTP, four jackpot tiers, a genuinely exciting free spins round, and the unpredictable Treasure Chest bonus makes it one of the most complete slot experiences on the platform.
