Will the luck of the Irish rub off on you? Try Rainbrew and find out! Microgaming and Just For The Win have teamed up to offer this colourful brewery-based video slot game. Why not pour yourself a cold one and settle down for some spins? But before you try the game yourself at one of our top rated online casinos, check out our in-depth review below. We have tested this and thousands of other games in great detail, so you know what to expect.

Rainbrew: inside the game

The setting for Rainbrew is a craft brewery, where the specialist beverage Rainbrew is produced. This magical colourful tipple is produced by elves and leprechauns, and served in overflowing tankards from the aged cask barrels. These items are the symbols you’ll find on the Rainbrew reels, along with lower paying celtic gemstones - plus wilds and bonuses.

The reels are surrounded by the brewing pipes, which carry colourful liquid along the top and bottom of the 5x3 layout. When the Wild and Rainbrew Free Spins features are triggered, symbols pass along these pipes and can land on any of the centre three reels

Horizontal reels

Rainbrew includes a special Sidewinder feature, where the top and bottom horizontal reels increase the chance of a win. The colourful blue and green pipes cover the top and bottom of the centre three reels, and they can add either wilds or scatters to the reels. Both can be activated at the same time for even bigger wins - and during the free spins feature, wilds on opposite reels can expand to form a full stacked wild on that reel.


Wild symbols appear on the base game reels. They are either green or blue, and they point to the matching horizontal reel with arrows. Finding one or more wilds causes the corresponding reel to scroll along, adding up to three wilds to the reels in the process. In the event that another wild with arrows appears, the second reel may also activate.

Rainbrew Spins

Rainbrew bonus symbols appear on reels 2 and 4. If both fall into place, the horizontal reels will trigger. Each will be filled with Rainbrew symbols. Land three symbols to unlock 6 free spins, with four extra spins added for each additional bonus symbol. During the free spins round, the Rainbrew symbol appears as a scatter, both in the main reels and the horizontal reels. One or more adds extra spins to the reel.

During Free Spins, both horizontal reels trigger with every spin. They are also packed full of wild symbols, so expanding wilds are very likely to trigger. This is where the game’s biggest wins can be found. If all wild reels are activated, players could win up to 2,720x their bet!

Tech and specs for Rainbrew

The published RTP for this online slot game is 96.02%, which is roughly comparable to the majority of slots on the market. It is a mid-volatility game, with a reasonable mix of small wins and bonuses. Players can bet anywhere from 10p to £100 per spin, and all wins are adjusted according to the wager. The maximum win from this slot is 2720 times the bet amount.

The game is mobile compatible, so you can play it on Apple and Android phones and tablets. Rotate your phone to portrait mode for the best gameplay experience. It runs on the Just For The Win gaming platform and utilises Microgaming’s Quickfire technology, plus the patented Sidewinder in-game feature.

A summary of the slot game

If you want state of the art graphics and a studio-quality soundtrack, Rainbrew might not be the right game for you. The game’s appearance is a little basic, with 2D symbols and very little animation. However, the colours are bold and bright and the fun characters keep things interesting. Plus, the horizontal reels look great, and the flow of wilds and bonuses to the reels brings plenty of excitement to the game.

The chance of big wins in the free spins feature is the most appealing aspect of the game. Free spins can keep stacking up as scatter symbols trigger them, so the round can go on for ages. Meanwhile, expanding wilds can cause the big wins to rack up quickly. For this reason, Rainbrew is sure to attract plenty of fans.
