Stakelogic releases Sunken City Riches with x15,000 max multiplier

New 1,024-ways slot uses persistent reel modifiers via a Treasure Map Meter and a Gem Meter that feeds a Mystery Pick Bonus.

Stakelogic has launched Sunken City Riches, a new 1,024-ways slot built around collecting scatter symbols to permanently unlock reel modifiers and build towards a Mystery Pick Bonus with a top multiplier of x15,000.

Progress is driven by Treasure Map Scatter symbols, which can land anywhere and feed two meters simultaneously. The Treasure Map Meter unlocks a new feature for every four scatters collected: Payway Maker, Symbols Upgrade, Add Wild Multipliers, and Split Symbols. Once unlocked, each feature remains active and can trigger at random on later spins, with multiple features able to land on the same spin.

Alongside this, the Gem Meter banks multiplier values carried by each scatter rather than paying them out immediately. Once 20 gems are collected, the Mystery Pick Bonus opens and carries the banked gems into a pick round, where players choose gears until the Collect Gear is revealed and the resulting multiplier is applied to the stake.

The slot also includes a Free Spins Feature triggered by three or more Free Spins Scatter symbols, with retriggers awarding three, four or five additional spins. Stakelogic said all features are available during free spins, with at least one guaranteed on each spin. Players can activate Super Stake™ for 50 per cent of the base bet to double their chances of triggering free spins, or purchase the bonus for 100x their stake.

James Jelliffe, Head of Slots at Stakelogic, said: “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, so the game a player is looking at after some spins is not the same game they started with.”

“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. It is one of our most feature-dense releases to date and we think players will enjoy piecing it together.”
