Rainbow Wilds is a 5x4 online slot with 1,024 ways to win. The game pays for the uttermost left reel in the left-to-right direction. Only lines with matching symbols on at least 3 adjacent reels are payable.

The important detail about the slot’s gameplay is cascading (tumbling) mechanics. All winning lines disappear from the board, and the spin continues. Symbols from the above positions will fall down to the empty spots of disappeared elements. New elements will fill empty positions of dropped symbols. Cascading continues as long as you get new winning combinations. Aside from the base game, Rainbow Wilds has the free spins rounds.

Rainbow Wilds RTP and Volatility

Rainbow Wilds is a high-volatile slot with an RTP of 96%.
It’s pretty obvious that Rainbow Wilds has a high variance. First of all, the paytable is not balanced at all, as the highest-pay five-of-a-kind line is 40 times greater than the lowest-pay one. Secondly, we are talking about the game with cascading mechanics. There is always a chance for a combo of winning lines during one spin. Thirdly, there are 3 different Wild symbols here, including sticky and expanding elements. Finally, a multiplier can be applied to your winnings during free spins. The slot’s RTP is average – 96%.
