Theme & Background

Rainbrew Slot Review - Wild Symbol

The graphics for Rainbrew are fantastic. The symbols all have an excellent vibe to them that makes them almost look like caricatures of real people. They occupy the space directly between photo realistic and cartoon that engages players. It creates a wonderful viewing experience for Rainbrew.

The background to Rainbrew puts you right into the brewery. With the barrels showing in the background letting you know that you are right there in the leprechaun’s place of work. It looks fantastic without overwhelming the visuals of the reels and overall it puts together a great view of the game.


Microgaming and Just For The Win have created an innovative slot with Rainbrew. The way the additional reels come into play ensures that it can potentially offer an incredible amount of ways to create winning lines. It still contains all of the usual features included with video slot games though, like wild symbols, scatter symbols and free spins. This means that despite the innovative feature it isn’t intimidating to players.

Sidewinder Feature

The Sidewinder feature is triggered when the top wild or the bottom wild symbol appear on the reels. The top wild can only appear on the second reel and the bottom wild can only appear on the fourth reel.  If only one of the wilds appears then only that additional reel will be opened up.

So if the top wild appears, the top additional reel will be opened. If both wilds appear then both additional reels will be opened. When only 1 set of additional reels are open then the ways to win is increased to 576, if both are open then it increases to a massive 1125.

The free spins feature on Rainbrew is triggered when 3 or 4 Rainbrew scatter symbols appear on the second and fourth reels. If you manage to get 3 symbols then you are awarded 6 free spins. If you manage to get 4 symbols then you are awarded 10 free spins.

During the free spins mode both of the additional reels are available for the whole duration. That means you get 1125 ways to win the entire time. That’s not the end of the bonuses though, during the free spins mode if a wild symbol lands opposite another wild symbol in the 2 additional reels they will join together creating an expanding wild.

During the free spins mode every time a Rainbrew scatter symbol lands on the additional reels another free spin will be added to the total free spins remaining.
