The Foundry Slot Demo by Void Studios

The Foundry by Void Studios Slot Overview

The Foundry by Void Studios frames its colourful mechanical forge with gears, riveted steel and floating cliffs. Its Cluster Pays gameplay and tumbling symbols share common ground with Sweet Fiesta, but here a hanging crate doubles its multiplier with every winning cluster.

Chain Crates adds a clever twist: a Lock preserves the multiplier for an extra winning spin. Distinct bonus modes deepen this high-volatility slot, with a maximum win of 25,000x the bet. Explore the forge through the free demo on BonusTiime, with no deposit or account needed.

The Foundry Slot Features

Chain Crates, the Forge Bonus, Degen Spin and Max or Zero give The Foundry its layered feel, with cluster tumbles, a crate multiplier that doubles as wins land, and a bonus menu that can be bought mode by mode.

Chain Crates

Every winning cluster of a base game spin is multiplied by the crate hanging over the board. The first winning cluster of a spin is multiplied by 2x, the next by 4x, the one after that by 8x, and the crate keeps doubling with every further winning cluster, up to 2,048x. A Lock symbol holds the crate on its current figure for one more spin of the same round, and that spin always wins.

Forge Bonus

FS symbols on the board, counted once it stops winning, open the forge bonus, and the number of them decides which named mode starts. Each mode comes with its own free spin count and starting multiplier, which is what makes The Foundry more than a standard cluster slot.

• 3 FS symbols open Ignition with 10 free spins and the multiplier at 1x.
• 4 FS symbols open Redline with 8 free spins and the multiplier at 2x.
• 5 FS symbols open Cataclysm with 10 free spins and the multiplier at 4x.
• 6 FS symbols in the base game or Extra Chance open Cataclysm with 10 free spins and the multiplier at 32x, and that bonus wins at least 2,000x.

In Ignition a winning cluster of 5 to 6 symbols adds 1 to the multiplier, 7 to 8 add 2, 9 to 10 add 3 and 11 or more add 5, while Bomb symbols take 1 to 10 off it, never below 1x. The free spins win without a multiplier and the bonus adds their wins up, then multiplies the total by the final figure. In Redline and Cataclysm the crate hangs over the board and multiplies every winning cluster, as in the base game: every free spin starts it at the figure the bonus opened on and it doubles with each winning cluster, up to 2,048x. A Lock carries the crate into the next free spin, which then always wins. Every winning cluster also fills one slot of a bar of 3, and a full bar doubles the starting multiplier of every later free spin.

Degen Spin

Before the board lands, the multiplier rolls to one figure from 2x to 2,048x, and every win of the spin, tumbles included, is multiplied by it. A multiplier of 256x or more always wins; under it, a spin that connects nothing wins nothing. This mode swaps the crate system for a single, highly volatile burst.

Max or Zero

Every spin drives the Max block down the board row by row on all 7 catapults, pressing them flatter on every row. When the block stops in the middle of the board, the spin wins the maximum of 25,000x, and a block that stops on any other row wins nothing. It is a direct all or nothing round with no paytable in between.

Bonus Buy

The mode menu sells six modes. Each one is an Activate card that stays on until you deactivate it, so its price is charged on every spin rather than once, and all six keep the same 96.70% RTP and 25,000x maximum win as the base game.

• Extra Chance: x4 the bet per spin, the base game with the forge bonus triggered about 5 times as often.
• Ignition: x100 the bet per spin, every spin starting Ignition with 10 free spins and the multiplier at 1x.
• Redline: x250 the bet per spin, every spin starting Redline with 8 free spins and the multiplier at 2x.
• Cataclysm: x500 the bet per spin, every spin starting Cataclysm with 10 free spins and the multiplier at 4x.
• Degen Spin: x100 the bet per spin, every spin rolling the 2x to 2,048x multiplier before the board lands.
• Max or Zero: x1,000 the bet per spin, every spin driving the Max block down all 7 catapults.

The Foundry Slot Review

The Foundry builds its identity from a bright forged theme, chunky metal framing and a board full of industrial symbols like hammers, chains and lanterns. The Cluster Pays layout suits that factory setting well, while the 7×7 grid gives the screen a busy, mechanical look without feeling messy.

Gameplay leans on high volatility and a feature set that keeps changing the risk profile. The base game uses Chain Crates, while the bonus menu adds Ignition, Redline, Cataclysm, Degen Spin and Max or Zero. That variety is a real strength, although the buy options also make the structure feel heavily tilted towards feature chasing.

The Foundry offers direct access to its bonus modes through feature buys, but longer sessions and feature buys do not improve its published RTP. The 25,000x cap gives it a serious ceiling, but the all or nothing feel of Max or Zero and the sharp swings from Degen Spin keep it unforgiving. The result is ambitious, specific and easy to remember.
