Slot Details

Rainbrew is a video slot with a 5×3 standard format and 243 ways in the base game. Activating one or two Sidewinder tubes will increase the game window to a 3-5-5-5-3 format with 576 and 1,125 ways. The cost for a round of beer ranges between 0.10 and 100 coins.

An average RTP of 96.02% and the medium volatility will make sure that the tasting tour is not ending quickly. JustForTheWin designed Rainbrew in HTML5 format, which makes it available for play on desktop and mobile devices.

The entrance to the leprechauns’ brewery with beer barrels stacked on both sides of the door is the fitting background on Rainbrew. A frameless game window resembles a brewing kettle. The two transparent horizontal tubes of the Sidewinder Reel sit at the top and bottom of the three centre reels. They will play a vital role on this game. A catchy Irish soundtrack will have players tip-toeing through their slotting sessions. Colourful animations are adding to the suspense of hitting big wins.

Rainbrew has 10 pay symbols, starting at the low end with five gem arrangements in green, blue, orange, purple and red colours. On the medium level, they are a smoke pipe, a beer tasting glass and a beer barrel. The two top symbols are the female and male leprechaun brewmasters. All pay symbols can appear semi-stacked up to two reels positions high.

Wild symbols appear only on reel two and four as well as on all three positions in the horizontal Sidewinder tubes. Based on the colour and arrow pointers, the wilds on the reels will trigger the Sidewinder feature. Scatters are the Rainbrew slot logo appearing on reel two and four only.

The Sidewinder Reel

The pay mechanic is a new JFTW feature to enhance the slot reels. It will take a few spins to fully understand how it works. A horizontal Sidewinder reel is placed on top and the bottom of the game window, covering the three middle reels. Both contain only wild symbols and Rainbrew scatters in the base game and free spins. Activating one of the reels will open the ways-to-win from 243 to 576 while triggering both will see that grow to the maximum of 1,125 ways. It can also trigger the free spins or add extra free spins during the bonus round.

Wild symbols on reel two or four will activate the Wild Sidewinder feature. The blue Top Wild, appearing on reel two, has arrows pointing up and thus will activate the horizontal Sidewinder reel on the top of the game window. The green Bottom Wild appears on reel four and has arrows pointing down, respectively activating the bottom Sidewinder reel. When wilds land simultaneously on reels two and four, then both Sidewinder reels are triggered.

Once activated, the respective Sidewinder reel will spin one time. Wilds can land in two versions that will end the feature or award an additional spin on the opposite Sidewinder reel. The standard wild in rainbow colours will end the feature and any potential wins are paid according to the pay table. The blue Top Wild will appear only in the bottom Sidewinder reel and award an additional spin on the top reel. Accordingly, the green Bottom Wild appears in the top Sidewinder reel only and awards then a spin on the bottom reel. This will continue until now pointed wilds will land on either of the reels. The maximum in the base game are three wilds on the top and three wilds at the bottom. Together with one or two triggering wilds, it would lead to 12 or 18 ways of winning combinations.

Free Spins with a Twist

Rainbrew scatters on reels two and four in one spin will activate both Sidewinder reels. One spin on each is awarded with only Rainbrew scatters on the horizontal reels. The free spins are triggered when minimum one further scatter lands on either of the Sidewinder reels. Three scatters will award six free spins, while four scatters will increase the number to 10.

During the feature, the Sidewinder feature is always active, and the game window is expanded to the maximum of 1,125 ways. After the reels stop on a free spin, each Sidewinder reel win spin one time to potentially reveal more wild symbols or Rainbrew scatters. Each Rainbrew scatter will add one additional free spin.

Only the rainbow-colored standard wild will appear on the Sidewinder reels. They can be single symbols or in blocks of two or three symbols. The kicker in the free spins is though when wilds land directly opposite on the same reel. They will expand to form a stack of five wilds and cover the entire reel. Overall, it can lead to having all three middle reels covered with wild symbols, which would award 125 ways of winning combinations. The best and only moment to hit the maximum win of 2,720x bet on Rainbrew.
