Subtopia isn’t a slot game we’ve reviewed on Online-Slot.co.uk but it will be coming in the next few days. The underwater themed game by Net Entertainment has 5 reels and 20 paylines. It’s quite different from most other slots and has a couple of good features. Firstly, there is the Random Multiplier feature which basically applies a multiplier randomly to your spins. You can get a 5x multiplier applied to your spins for big wins!

There is a Free Spins feature (as with all NetEnt slots) which uses a Multiplier Meter feature. It works quite similarly to the Random Multiplier feature but your free spins will be multiplier between 2 and 6 randomly. The minimum you will get is a 2x multiplier which is good.

Mr Green Casino is an online casino I have highly recommend as a slots player. They have games from Betsoft, IGT, Microgaming and Net Entertainment all in 1 place – the slots are all available to play in your browser without having to download any software.

When it comes to slot games, you can play Cleopatra, Da Vinci Diamonds and Monopoly Plus (IGT). Betsoft offer 3D slots such as Mr Vegas and Lost. You can also play Tomb Raider Secret of the Sword and Thunderstruck II which are Microgaming classics. Finally, why not try Scarface, Piggy Riches or Gonzo’s Quest? These 3 NetEnt slots are some of the most games around at the moment.
