Visually, Rainbrew is played on a 3, 5, 5, 5, 3 reel set with 243 ways to win. With an Irish luck theme and set in a leprechaun’s brewery, symbols include 4 Celtic style objects, smoking pipes, mugs with special brew, barrels full of special brew and 2 leprechaun characters (female and male). The male character is the most rewarding giving you 8 times your stake for 5 across a payline.

Rainbrew comes with 3 wild symbols – the Regular Wild, Top Wild and Bottom Wild. The wilds substitute for all symbols bar the Free Spins scatter. The Regular Wild only appears on horizontal reels whilst the Top Wild symbol only appears on reel and at the bottom. The Bottom Wild only appears on reel 4 and the top horizontal reel.

The game comes with an innovative Sidewinder feature – this is played when a Top Wild activates the top horizontal reel and a Bottom Wild activates the bottom horizontal reel. The number of ways increases to 576 ways to win (1 activated horizontal reel) and then 1,125 ways to win (2 activated horizontal reels). This allows you to form bigger wins basically.

It’s all about the Free Spins feature which is accessed when the Free Spins scatter appears on reels 2, 4 and the horizontal reels – both horizontal reels are then activated and spin. 3 Free Spins symbols will give you 6 free spins whilst 4 of them will reward you with 10 free spins.

Look out for wilds stopping on the same position on both horizontal reels and these will connect and expand to give you Regular Wilds on the reel in-between them – this can lead to 3 wild columns on each free spin. Furthermore, every Free Spins scatter landing will give you 1 additional free spin.

Rainbrew may sound confusing but in reality, it’s quite simple – it’s all about playing on 1,125 ways to win with the connecting/expanding wilds in the Free Spins feature. If you manage to get 3 fully wild reels, this can lead to wins of 2,720 times your stake! Overall, a good Irish luck themed slot which is different in terms of bonus features – if you like the theme, Shamrockers Eire to Rock from IGT is recommended.
