The Naughty Ninja game is about two Ninja ladies, fighting against some aliens or creatures saving the world from them. This game has scatter symbols, free spins feature, re-spin feature, which I like the most and the wild stuck feature. The silver star symbols which is wild one, always and only lands on the the reel three so that way, you got the re-spin feature.
So playing this game, when the free spins are triggered, actually the e-spin feature, then the silver star is stacked on the reel 3 and its becoming expanding wild, so the next re-spin is an free spins and the winnings from that re-spin it can be huge, well that depends on the winning combination you will hit.
The wild symbol is the Ninja lady with the red top called Bubble, where she substitutes all the other symbols on the reels except for the silver star, which is the scatter symbol. The last time I have played this slot, was on Liberty Slots Casino, where there was an Freeroll Tournament, which you can get some free chip playing this slot. Because they lower the starting credits from 50$ to 20$ I started to play with the 2.50$ per spin. So I was playing for 10 rounds and lost the bonus credit very fast, although I think that this game, like all WGS games, with the lowest bet, can bring you solid amount of money. I do recommend this slot, just give it a shot, you might like it !
