Theme

6.9 

Octagon Gem is a gem-themed slot, with a simple design, reminiscent of classical slot machines. So while the visuals of this game are not particularly innovative and mind-blowing, the Octagon Gem still looks fine and vibrant: with lovely purple scenery that looks like a gem, to the transparent reels and occasional sounds the game makes when you interact with it. Plus, the symbols also look pretty.

In an Octagon Gem, you have several types of symbols: the basic ones look like gemstones and the special symbols are Wild and Scatter. The Wild that looks like a golden star will substitute for all symbols except the scatter and it will appear only in the 3 central reels. Plus, the Wild will activate the Octagon Gem feature. Meanwhile, the cart with gems is the Scatter and not only it will pay 2x, but will also unlock the Bonus Feature if you land at least on 3 of these symbols.
