Treasures Untold by Foundry Slot Overview
Treasures Untold leans into an ancient temple treasure theme with teal lighting, gold trim, carved stone detail, and a polished fantasy interface. The chest-and-key motif gives it a clear identity, while the character art and ornate framing keep the presentation sharp and memorable.
This is a high-volatility 5×4 fixed-payline slot with 20 lines, but the real twist is how Keys collect chest prizes across the board. Three bonus modes and a 25,000x max win add variety. Try the free demo on BonusTiime.

Treasures Untold Slot Features

Keys and Chests drive the action in Treasures Untold, while Scatter triggers, bonus levels, and the Bonus Hunt option keep the gameplay varied and tactical.
Scatter
Scatters appear only in the base game and land anywhere, with at most one per reel. Landing 3, 4, or 5 Scatters triggers Treasure Hunt, Golden Pursuit, or Untold Riches. They do not appear during bonus rounds, so their role stays tightly focused.
Key
Keys land in every bonus game, and in the base game only through a Treasure Surge. When a Key lands, it collects the prize from every chest on the board. If several Keys land together, each one collects the full chest total separately, and a Key can also substitute for any paying symbol on a line.
Chests
Chests appear in the base game and every bonus game. Chest prizes are multiples of your bet, and every chest counts as the same symbol on a line; in Untold Riches, only Bronze chests show their prize before collection. That means 3 or more matching chests from the leftmost reel can pay, even before a Key collects their prize.
Treasure Surge
Treasure Surge only appears in the base game and Bonus Hunt. When a spin shows at least one chest, 1 to 3 Keys can drop onto the board at random, never on a chest or a Scatter. Each Key has its own multiplier of x1, x2, x3, or x5, and each one collects the full chest total.
Amethyst Key
Amethyst Keys appear only in Treasure Hunt and Golden Pursuit. They work like Keys, but they also carry their own multiplier, which multiplies the multiplier of the spins being played. For example, an Amethyst x5 Key during x3 spins collects the chest total x15, and it still counts as one Key towards the next level.
Treasure Hunt
Landing 3 Scatters starts Treasure Hunt with 10 free spins. Every Key adds to a level meter, and collecting 4 Keys adds 10 more spins at the next multiplier: x2, then x3, then x10. The bonus can reach 40 spins in total, and extra Keys count towards the next level.
Golden Pursuit
Landing 4 Scatters starts Golden Pursuit with 10 free spins. It plays like Treasure Hunt, but each level needs only 3 Keys before it adds 10 more spins at the next multiplier: x2, then x3, then x10. The bonus can also reach 40 spins in total, with extra Keys carrying over.
Untold Riches
Landing 5 Scatters starts Untold Riches with exactly 10 free spins. Every spin includes at least one Key and one chest, while Bronze chests show their prize and all other chest prizes stay hidden until collected. Each Key has its own multiplier: x2, x3, x5, x10, or x25.
Bonus Hunt
Bonus Hunt is a mode you can activate to improve the chance of hitting a bonus round on every spin. Each spin becomes about 4 times more likely to trigger a bonus game, and Treasure Surges appear more often. It keeps the game structure intact while changing the odds.

Treasures Untold Slot Review
Treasures Untold builds its identity around a temple treasure setting, but the real hook is the way Keys and Chests work together across the reels. The teal highlights, gold framing, and statue like presentation give the game a polished fantasy look without pretending to be more than a feature led slot.
The gameplay leans on a high volatility model, with chest collection available in both the base game and bonus rounds. Treasure Hunt, Golden Pursuit, and Untold Riches each change the value of Keys in a meaningful way, and that progression gives the slot more shape than a standard fixed payline release.
Treasures Untold suits players who want a bonus driven slot with a clear mechanic and a respectable 25,000x ceiling. The 96.40% RTP helps, but the strong swing profile means it suits patience more than constant small returns. It will appeal most to players who enjoy structured feature rounds and collectible-style payoffs.
Treasures Untold Slot FAQ
How Does Treasures Untold Trigger A Bonus?
Treasures Untold triggers bonus rounds by landing Scatters in the base game. Three Scatters start Treasure Hunt, four Scatters start Golden Pursuit, and five Scatters start Untold Riches. Scatters land only in the base game, and they can appear anywhere, with at most one per reel.
What Does The Buy Bonus Menu Offer?
The Buy Bonus menu offers Bonus Hunt, Treasure Hunt, Golden Pursuit, and Untold Riches. Bonus Hunt costs x3 the bet per spin and makes each spin about 4 times more likely to trigger a bonus game. Treasure Hunt costs x100 the bet, Golden Pursuit costs x250 the bet, and Untold Riches costs x500 the bet.
What Is The Maximum Win In Treasures Untold?
The maximum win is 25,000x the bet. If the game reaches that limit, it ends the current round immediately and credits the capped amount. During free spins, hitting the maximum win returns the game to the main screen and forfeits any remaining free spins.

Keys collect the prize from every chest on the board. In the base game, they appear only with a Treasure Surge. Keys can land in every bonus game and can also substitute for paying symbols on lines, although a line made only of Keys wins nothing.
