Rainbrew is a game developed by Microgaming in partnership with Just For The Win. This means that players enjoy the best of both worlds, as they spin the reels of a licensed slot, with unique game mechanics. Normally the game has 243 winning ways, but these can be increased to 1125 when players activate the new Sidewinder Feature.

This is only available when Free Spins are triggered, so players win twice when they get to spin the reels for free. The number of bonus rounds awarded ranges from 4 to 10, depending on how many Rainbrew symbol are unveiled. Inspired by Irish folklore it checks all the boxes for this genre, with symbols depicting leprechauns, lucky four leaf cloves, drinks and other specific symbols.
