About the Online Slot Game

This game more than matches the create quality of Microgaming's online slots. We really enjoyed the exciting gameplay available in this game. Rainbrew is a 3,5,5,5,3 game, with 243 to 1125 ways-to-win! There is a very generous 96.02 return-to-player-percentage (RTP). Bets can be set at a range of 0.10 tow 100 coins. Giving players the ability to play for big bucks, or even just for fun!

For those who love cash, and who doesn't? There is a gigantic non-progressive jackpot. This jackpot will multiply the line winnings by 2,270. We are a bit overwhelmed, we need a drink! Rainbrew is also available on mobile phones, meaning you can play anywhere and at any time!

We love the playful music featured in this game. The soundtrack is beautifully composed. While playing, we heard authentic Celtic and Irish jigs. We were dancing around the office, and were all humming in the shower all week! The other sound effects were the traditional slot machine sounds we all know and love. It took us back to the arcades we spent our childhood in!

Even more impressive, are the stunning visuals in the game. The background illustrations are strikingly pretty. We loved the oak barrels, and the authentic maple pub floor boards.

The symbols in the game are also amazingly illustrated. The lower-paying symbols are represented by Celtic emblems. These are pretty designs which we would love to see turned into a necklace! These emblems have precious stones within a golden trim. The precious stones include green emeralds, blue sapphires, red rubies and yellow citrine!

The medium-value symbols are the Celtic smoke pipe, filled with the best Irish tobacco. A beer tankard, filled with Ireland's best ale and a barrel of said beer. The highest-paying symbols are the female and male leprechaun brewmasters. They are both amusing characters, dressed in traditional leprechaun garments.

Leprechauns are an important aspect of Irish mythology. They are said to be small fairies who wander around the countryside causing mischief. They are normally depicted wearing green outfits. These are usually suits with top-hats, black belts with golden buckles. They are usually drunk and are in search of a pot of gold under a rainbow. If caught by a human, they can grant their owner three wishes. And, we know what our three wishes would be: we want to win the jackpot on Rainbrew!

This game uses the commonly implemented WILD feature. In this game the WILD is the word 'WILD' in colourful rainbow colours. This symbol can replace all the other symbols, bar the SCATTER. The SCATTER is represented by the Rainbrew logo. These can unlock many more bonuses and features. This includes the Sidewinder Feature and Free Spins
