With a unique 3,5,5,5,3 reel layout, Rainbrew offers players 243 ways to win, which can expand up to 1125 ways during the game.

Bonus Features

Rainbrew’s Sidewinder Feature is the heart of its bonus offerings, providing a thrilling gaming experience. Here’s a breakdown of the key bonus features:

  • Sidewinder Feature: Increases the ways to win from 243 to 1125 by activating one or two horizontal reels.
  • Free Spins: Triggered when Rainbrew symbols land on reels 2 and 4, awarding 6 or 10 free spins. During Free Spins, the Sidewinder Feature is always active, and Wilds can connect to create Expanding Wilds.
  • Expanding Wilds: Occur during Free Spins when Wild symbols stop in the same position on both horizontal reels, enhancing win potential significantly.
  • Additional Spins: Each Rainbrew symbol landing on the horizontal reels during Free Spins awards one extra spin, prolonging the excitement.

These features not only add to the excitement but also significantly increase the chances of a big win.


Rainbrew features a rich tapestry of symbols, each adding to the game’s Irish brewery theme. Here’s a quick overview:

  • Low-value symbols: Represented by various Celtic objects, adding a touch of Irish charm.
  • Premium symbols: Include tobacco pipes, mugs, barrels, and male and female leprechauns, with the male leprechaun being the most valuable.
  • Wild Symbols: Come in three varieties – Regular, Top, and Bottom Wilds, each playing a crucial role in activating the Sidewinder Feature.
  • Rainbrew Scatter: Triggers the Free Spins and the Sidewinder Feature when landed in specific reel positions.


Starting with 243 ways to win, Rainbrew’s innovative gameplay allows players to expand their winning possibilities up to 1125 ways. This is made possible through the activation of the Sidewinder Feature, which adds horizontal reels filled with additional symbols, thereby increasing the number of paylines. Players can look forward to this dynamic shift during both the base game and the Free Spins round, offering a refreshing take on traditional slot payline structures.
