Verdict
A monkey in a diving suit exploring a drowned city is a daft premise, and Stakelogic runs with it happily.
Medium volatility makes the session feel balanced, and 96.01% RTP is right around average. Play it if you like a game with several progress systems to watch at once. Skip it if you prefer your slots with one simple bonus and nothing else.

How it plays
The base game uses five reels and four rows, with a ways count that runs from 1,024 up to 7,776. Ways to win means matching symbols only have to sit on neighbouring reels from the left, in any row, so the higher that count climbs, the more combinations a single spin can form. The art is bright underwater fantasy, with sunken ruins and the diving monkey as the mascot. Three systems sit around the reels. A Treasure Map Meter fills as you play, giving a longer-term goal across a session. A Mystery Pick Bonus puts a board of gold gears in front of you to choose from. And Sunken Free Spins are the main event, where multipliers come into play and push toward the game's 15,000x ceiling, a figure that's there for scale rather than something you should expect to see. Wilds help complete ways wins in the base game, and there's a bonus buy for going straight to the feature. Stakes run from 0.2 to 100. Medium volatility means a steady middle rhythm, with dry spells that rarely drag on too long. A sitting tends to move between small ways wins, progress on the map, and the occasional bonus, which gives it more texture than many games that rely on one trigger.

Who it's for
Good for anyone who likes a game with a sense of progress, where the map meter and pick bonus give you something to follow between free spins. The medium volatility makes it approachable, and the 15,000x ceiling keeps the free spins interesting. Players who like a light, silly theme with an underwater setting will enjoy the look. If you want a stripped-back game with just reels and one bonus, this will feel busy.
