Rainbrew is a slot machine that’s going to be available only at casinos using the Microgaming or Quickfire platforms, being designed as an exclusive for this developer by JFTW. The young company launches all its games at Microgaming, with which they have a deal to supply them with content, a new strategy that the bigger company is employing starting from 2018.

As for the game that’s available under the Rainbrew name, this Irish themed slot features 243, 576 or 1,125 ways to win, on a game area that has 3-5-5-5-3 symbols for the reels active at its best moments. Several types of wild symbols, scatters, free spins and an impressive Sidewinder feature will all contribute to the 96.02% RTP that’s available in the game. The biggest rewards can deliver up to $136,000 for a single round of Rainbrew.

Betting and Prizes

The smallest amount that you can invest to get the reels spinning can be just $0.10, but for the players that want a shot at a life-changing prize, there is the option to go up to $100 with the wager. There are 10 coins in use.

While individual wins will not offer you huge payouts, the best one delivering $800 when the wager is at its highest, the game can pay big once you reach the Sidewinder feature. The upper limit of the amount you can get from a single round is $136,000.

RTP wise, we’re looking at a number that’s high enough, 96.02% being in the area that most slots are hitting these days. The developer has let us know what makes up that percentage, and where the wins are expected to be coming from. The Sidewinder feature is going to do most of the heavy lifting, with 50.66%  being its contribution to the RTP. The Free Spins are next, with 27.93%, while the base game only pays 17.43% back to the player.


One of the features that I’ve found very interesting in Rainbrew is the presence of those top and bottom horizontal reels, which you can unlock through special wild symbols that appear in each area. There is a regular wild as well in the game. All these feature symbols will be usable as substitutes when they appear on the right reel. It’s obviously easier for a combo to form in the ways to win system, since you can use the wild in any position as long as the reel is right.

The base game has 243 ways to win, but if you manage to unlock one of the horizontal reels you get to 576 ways to win. Unlock both horizontal reels, to reach 1,125 ways to win. This is the Sidewinder feature, which is responsible for offering the biggest payouts of the game.

The free games can be quite profitable as well, particularly since they have the Sidewinder feature always active. You are required to have a scatter appear on the reels 2 and 4, as well as the horizontal reels. You can get 6 or 10 free spins this way.

Theme & Design

It’s a theme that’s based on the leprechaun’s story, so the Irish inspiration is clear here. Luckily, I’ve found excellent graphics in this slot machine, insuring that the game will be enjoyable for all players that will try it, even if they played other Irish slots before. The creator of the game chose to add a male and a female leprechaun to the list of symbols, along with pipes, beer, barrels and various Celtic-inspired icons.


Players that want a well-designed Medium volatility slot, will likely enjoy the unique features and the graphics offered in Rainbrew. You will find the game at any Microgaming or Quickfire casino.
