How to Play

A simple step-by-step guide will help you start playing Rainbow Wilds:

  • Visit the online casino and find the game in the lobby
  • Start the slot and wait until its content is loaded
  • Press “Continue” to enter the main interface
  • Press the coins icon and then set the bet size by clicking on arrows. The betting range is €0.5-50
  • Check rulebook and paytable
  • Adjust the slot’s settings if you want to
  • Spin the slot either manually by pressing the play button or automatically

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%.



Welcome to Wonderland, where Leprechauns with pots of gold are hiding in the high clover. Feel the magic of beautiful Irish nature. You’ll see berries and fruits on the gaming and a marvelous landscape of green nature. You can feel the adventurous atmosphere while hearing traditional Irish music and watching explosions of winning lines. Details like a banner with clover leaves or an expanding rainbow make the slot unique.

The slot’s collection of symbols is really big. There are 14 different elements in the game, including 3 wilds. 11 regulars can be divided into 2 groups – high-pay elements (berries) and low-pay ones. A full list of regular-pay symbols with their respective payouts is available below:
