I really like the wild re-spins feature which I was triggering quite often the last time I played this game. To activate this feature you need at least 3 King Kong symbols and they do not have to be on an active pay line. I suppose that for this reason you can easily trigger the bonus. I got 3 re-spins and the King Kong symbols are sticky which means you can win a lot during those 3 spins only. I even got 60 euros win and I was playing the game on minimum bet of 0.20 only. I had at least 2 wilds on the first 3 reels and 1 on the fifth reel. This is probably my favourite feature.
There is one more feature in this game called the Skull Island Bonus. I have triggered this feature only once even though I have played this game numerous times. To trigger this bonus you need 3 or more Kongo logo symbols. Then you have a map with 13 choices where you have to match 3 creatures and they will award you with a multiplier. You would like to see T Rex here because it will give you x 20 multiplier. I got 3 Brontosaurus and I got only x 10 multiplier. This is a game I play from time to time and I would highly recommend it. Next time I would probably try the Big City Mode.
