This game has only one feature which is free games. When you will get 3 or more scatter symbols on the reels you will get 10 free games. During those free games/spins Igor may add up to 3 wilds to 1 or more reels. You can also get more additional free spins if you get more than 2 scatter symbols. Beside this feature there is also some ˝bonuses˝ or modes. During base game Igor may add wild to 1 or more reels. This bonus is called as Igor wild bonus, there is one more bonus which is called Igor Scatter bonus. After any game Igor may add scatter to 1 or more of reels 2, 3 and 4.
I like that scatter bonus because sometimes you can get free games even if you didn't get three scatters on the reels at that spin. I triggered once free games like that, Igor gave me a third scatter and I entered free games. Beside this mode I also like wilds. Wild bonus appears quite often, but the payouts are not so great. My best winnings were around x15 bet when I got 3 wilds on the active payline. Otherwise I think this game is quite good, but I do not like to play NextGen software games so much. Mostly because of their payouts, I never got any decent, big win from their video slots and I rather try my luck at video slots where I know that you can get really big win with some minimum bets. I will rate this game with 7 out of 10 possible stars.
