Brew yourself up some magic!
Rainbrew is a 5 reel game and each reel is 3 symbols high. It does not use standard paylines. Instead three or more matching symbols anywhere on adjacent reels starting from the left side of the reels constitutes a win. This is equivalent to 243 standard paylines.
Alongside the 5 main vertical reels there are two horizontal reels, one at the top and one at the bottom of the vertical reels. These are not always active but when they do spin can land additional Wild symbols increasing the number of possible winning combinations up to a maximum of 1125.
There are three different Wild symbols when playing Rainbrew. The multicoloured Regular Wild symbol only appears on the horizontal reels. The blue Top Wild symbol only appears on vertical reel 2 and the bottom horizontal reel. The green Bottom Wild only appears on vertical reel 4 and the top horizontal reel.
There are two bonus features when playing Rainbrew. The first bonus feature is activated when you receive either the Top Wild or Bottom Wild. When this happens it will activate the corresponding horizontal reel which will spin potentially awarding additional Wild symbols. The horizontal reels can also be activated if you receive the ‘Rainbrew’ logo symbol on both reel 2 and 4 in which case both the top and bottom horizontal reels will spin.
The second bonus feature is activated if you receive 3 or more of the Rainbrew scatter symbol anywhere on the reels. When this happens you will be awarded 6 or 10 free spins depending on how many Rainbrew symbols you received. During the free spins both horizontal reels are active on every spin. Horizontal reels also contain Rainbrew scatter symbols. If you receive a Regular Wild symbol in the same position on both horizontal reels the Wild symbol will expand to cover the entire reel. Each Rainbrew symbol you receive awards an additional free spin.
Rainbrew offers up a game format that we genuinely haven’t seen before. The game is visually very sleek. The bonus features are fun without being stunningly unusual. The House Edge is within the range we’re commonly seeing used in modern slots releases, albeit at the top end. All in all this is a decent game without being spectacular.
