Subtopia Slot Review & Game Bonus

It’s been a long time since software providers NetEnt slots first made a splash with their popular Subtopia slot, but the promise of unlimited free spins has kept most deep sea explorers coming back for more.

A five-reel, 20-payline game, Subtopia is set on a submarine deep beneath the waves. A viewing window looks out over a sunken city not a million miles removed from the legendary civilisation of Atlantis, while a colourful cast of divers, scientists and engineers account for the majority of the game’s unique symbols with the low value icons, the wild and the scatter being the only exceptions.

Playable from as little as £0.20 per spin with all paylines active, the Subtopia slot machine can be enjoyed across all desktop, mobile and tablet devices and boasts a healthy base game jackpot of 2,000x players’ line bet. On top of that, a bonus round promises potentially unlimited free spins – with a random multiplier being applied to any winnings players accrue to ensure their bankroll remains afloat under pressure.

Depth Charge

In truth, this is the only real bonus feature included in Subtopia, so it’s just as well that it’s a particularly good one. In order to trigger it, players need to land three, four or five compass symbols scattered anywhere across the game’s five reels, with this causing a colourful new dial to appear on the console.

This new dial is vitally important as players will now technically receive an unlimited number of free spins so long as it doesn’t stop on a skull and crossbones symbol. Thankfully, there are other outcomes available here – namely a 2x, 4x or even a 6x multiplier being applied to any winnings during that spin.

The dial will be reset in a new position at the start of each bonus game, meaning multipliers and free spins will doled out indefinitely until a skull and crossbones is hit. When this happens, players will be returned to the base game to start again, but not before they receive the entirety of their bonus win.


While more demanding players might scoff at the Subtopia slot solitary bonus feature, once they experience it for themselves they’ll see why the game has proved such an enduring classic in the NetEnt line-up.
