Katana is an Asian themed slot machine from Novomatic, this exact game is also known as Shogun in Novomatic's land based offering of slot machines. Katana is a 20 lines slot with one main feature, and that’s the free spin feature. During the free spins all wild symbols upgrades and become expanding wilds. That means that it's possible to get a full screen of wild symbols during the free spins on Katana. If you manage to hit this combination during the feature, a prize of 1.000x the total stake per spin is rewarded to your account. I'm a bit picky when it comes to slots and stuff, and I'm always a bit upset when I see that Greentube have failed to publish this game in the correct size, resulting in those ugly black bars on each side of the game. But don't mind that, the game itself is a very good game and it's known for being an easy slot to re-trigger if you first manage to get the free spin feature. The RTP is set to 95.02%.
