Sunken City Riches by Stakelogic sets a five-reel, four-row video slot in an underwater lost city of ancient ruins, treasure maps and gems. Wins form in ways across the grid, while Treasure Map symbols feed two meters that can turn ordinary spins into feature rounds.
Quick take: A pair of linked meters leads from map symbols to a gem-fueled Mystery Pick.
Theme and Gameplay
The lost-city setting gives the game a clear treasure hunt to follow. On ordinary spins, watch for Treasure Map symbols: they contribute to the Treasure Map Meter and also carry cash values toward the Gem Meter. That gives the symbols two jobs, connecting feature effects with the values that can build toward a separate bonus. Ways-based wins spread across the five reels, so the focus is on matching symbols across the grid rather than following fixed paylines.
Slot Features
When the Treasure Map Meter unlocks a feature, possible effects include copying a symbol from the first reel across the other reels, upgrading a paying symbol, adding multiplier Wilds, or splitting symbols. These effects can change the shape or value of a result in different ways. Wilds substitute for regular symbols, and some carry multipliers from 1x to 5x. The Gem Meter leads to a Mystery Pick: collected cash values spread across the grid, and collecting the end symbol ends the round. Three, four or five Scatters award eight, ten or twelve Free Spins. At least one random Treasure Map feature triggers on each free spin, giving the bonus a feature effect to watch on every turn. A Feature Buy can start Free Spins.
Feature focus: Keep an eye on both meters when Treasure Map symbols land. Their feature effects can change the reels, while their cash values also help build toward the Mystery Pick; the two routes make the same symbol relevant in different ways.
RTP and Win Potential
The game lists a 96.01% RTP and a 15,000x maximum win. The maximum is a stated ceiling, not a typical result. Free Spins start at eight, ten or twelve depending on the number of Scatters, while the Treasure Map effects and Gem Meter add other paths for results to develop.
My Thoughts On This Slot
Following a Treasure Map symbol means checking two places: the feature meter it feeds and the cash values contributing toward the Gem Meter. That shared starting point gives the underwater treasure hunt some coherence. A map matters beyond the immediate ways result, although reading its contribution asks more attention than simply checking the reels for a win.
Free Spins sharpen that idea by including at least one random Treasure Map feature on every turn. Copying symbols, upgrades, multiplier Wilds or splits give you a reason to examine how each result develops. Alongside the Mystery Pick, where the end symbol closes the round, that creates plenty to follow. The variety is worthwhile if you enjoy linked objectives, but the meters and changing effects make this a busy choice for a plain reel game.
Final Take: A layered underwater slot where each Treasure Map symbol can advance two different prize paths.
