Play Rainbrew from Microgaming for free

About Rainbrew

Rainbrew slot game is an innovative offering from Microgaming, Just For The Win. Within the base game, Rainbrew has a 5 reel, 3 row setup with 243 paylines, but if the unique Sidewinder feature is triggered, the paylines can increase up to 1,125. Rainbrew’s RTP sits at a healthy 96% and is considered a medium variance slot.
The special features within the slot game certainly up the ante when it comes to potential winning opportunities. First of all, landing wilds on reels 2 and 4 will trigger the Sidewinder feature which changes the shape of the game by adding more rows to the middle reels, and therefore more paylines. These can be added on the top of the reels or on the bottom, or both. These new rows feature wilds that can substitute for other symbols and scatters which can trigger free spins. Landing rainbow scatters will also activate the Sidewinder reels, and landing 3 scatters will trigger a round of 6 free spins, while 4 scatters will award 10 spins. During the free spins, landing more scatters will produce more spins and there is also the possibility of landing the expanding wild feature that can see you win increase to 2,720x your initial bet.
