Expect glowing reels, thrilling suspense, and plenty of surprises. Open chests to trigger the Hold & Win bonus game and chase jackpots. There’s no better time to become a legendary treasure hunter than now.
Set Your Play Size

Before opening the first chest, choose your ideal play size. Just use the play level arrows to adjust the number to what feels best for your session. You can also easily test different levels between rounds as you explore the treasure chambers.
Auto-Play and Turbo Mode

But why hit spin every time? Switch on Auto-Play to let the symbols roll by themself while you track the action. Looking to turn up the tempo? Activate Turbo Mode to reveal what’s inside those chests at top speed.
Special Symbols

Bonus Symbol
Bonus symbols land across both the main game and the Bonus Game. Each one shows its own prize value. Just keep in mind: to actually claim those rewards, you’ll need to trigger the Bonus Game.

Sticky Symbol
Watch out for Sticky symbols during the base game. Every time one hits the reels, it locks in place, giving a multiplier up to x10 your total play size. It stays in place across spins until the Bonus Game activates. Only then does the Sticky symbol award you.

Boost Symbol
Boost symbols supercharge the reels by adding their values to all visible Bonus symbols. Each Boost rewards a random multiplier up to x10.

Mystery Symbol
Save the best surprises for last! Mystery symbols open up only at the very end of the Bonus Game, revealing one of four exciting rewards with multipliers up to x100.

Collect Symbol
Collect symbols landing on the reels accumulate prizes from all Bonus symbols present on the reels. But each Collect symbol activates only once.
Bonus Game

Look above the reels, and you’ll notice three locked chests – the Red Chest (BOOST), Green Chest (MYSTERY), and Purple Chest (COLLECT). Each can unleash game-changing special symbols.
Landing 4 regular symbols along the center row triggers the main event: the HOLD AND WIN Bonus Game. Whenever the feature begins, the chests above have a chance to crack open at random, regardless of which symbols landed on the reels:
Red Chest: Powers up your round with BOOST symbols
Green Chest: Adds suspenseful MYSTERY symbols to the board
Purple Chest: Introduces reward-gathering COLLECT symbols
If the chests stay shut, you’ll dive into a classic HOLD AND WIN session. But the real excitement sparks when multiple chests open at the same time – like pairing Red and Green together to flood the reels with both BOOST and MYSTERY symbols for massive win potential.
Special Features

Mystery Feature
This feature lets you win Jackpots. While active, during the Bonus Game you may catch mystery symbols that, at the end, reveal one of four prizes:
MAX JACKPOT: x100 your total play
MID JACKPOT: x50 your total play
MIN JACKPOT: x20 your total play
Regular Prize: x7 or x10 your total play

Collect Feature
When the Collector feature powers up, it sweeps across the reels and gathers every single prize value from all active Bonus symbols on the reels. Instead of waiting to count them one by one, the Collector pulls them straight into one massive reward.

Boost Feature
When the Red Chest unleashes the Boost feature in the Bonus Game, special multiplier Boost symbols land. Each one carries a value up to 10x your total play and instantly adds that prize to every single Bonus symbol in view.

Chance Game Feature
Want to push your luck and multiply your rewards? Go head-to-head with the dealer! Pick one of four face-down cards in the Chance Game:
Beat the Dealer: Doubles your current reward with up to 10 attempts.
Draw: Matching the dealer’s rank keeps your reward safe and lets you try again.
Joker Advantage: The Joker beats everything. And only you can draw it.
Lose the Round: A lower card clears the round's reward and ends the minigame.
Prefer to lock in what you've got? Tap Take Win at any point to step away with your collected prizes.
