Stakelogic launches Sunken City Riches, 1,024‑ways slot with x15,000 multiplier

Stakelogic has launched Sunken City Riches, a 1.024 ways slot offering a top multiplier of x15,000 and a permanent progression system driven by scatter symbols, the studio’s press release dated 26 October 2026 states. The game combines two meters — the Treasure Map Meter and the Gem Meter — that work in parallel to unlock reel features and a Mystery Pick bonus.

Main mechanics and unlockable features

Progress in play is driven by Treasure Map Scatter symbols, which can land in any reel position and feed both meters simultaneously. Every four collected scatters activate the Treasure Map Meter and unlock one of the following features, which remain permanently active once obtained and can appear randomly on subsequent spins:

• Payway Maker copies a random symbol from reel one across the remaining reels.

• Symbols Upgrade promotes a random paying symbol to the highest value on the paytable.

• Add Wild Multipliers places between one and three multiplying wilds on the grid.

• Split Symbols splits up to 10 symbols of different types.

Wilds appear on reels two to five, substitute for all paying symbols and can be split and multiplied. More than one feature can trigger on the same spin.

Gem Meter and Mystery Pick Bonus

The Gem Meter banks the multiplier values carried by scatters instead of paying them immediately. Values are colour-coded: green starts at 1x, blue and red increase through higher tiers, and purple covers the 500x to 1,000x ranges. When 20 gems are collected the Mystery Pick Bonus opens and the banked gems move into a picks round. Players select gears until they reveal the Collect Gear; the resulting multiplier is applied to the stake.

Free Spins, Super Stake™ and bonus buy

Free Spins Scatter can land on all reels; three or more trigger the free spins feature, and retriggers award three, four or five additional spins. All features can occur during the free spins round, with at least one feature guaranteed on every spin. Players can enable Super Stake™ by paying 50% of the base stake to double their chances of triggering free spins, or purchase the bonus directly for 100x the stake.

"Sunken City Riches is built around progress that sticks. Instead of handing players one feature and then resetting, the Treasure Map Meter keeps adding to what the reels are capable of," said James Jelliffe, Head of Slots at Stakelogic.

"Pairing that with the Gem Meter gives players two things to chase at once, and because the multipliers are visibly banked before they are paid, the Mystery Pick Bonus arrives with real weight behind it," Jelliffe added.

The title places the player amid the sunken ruins of a lost civilisation, with stonework and clockwork machinery resting on the seabed. The release was announced from Malta on 26 October 2026. You can find the game page in the [casino](/casino) section of the editorial site.
