Have you ever wondered how rainbows are made? Well, we’ve got two bits of good news for you! One, they’re made by little leprechaun workers who churn them out from a factory, and two: They’re alcoholic! Don’t ask us how, but there doesn’t seem to be much logic in Rainbrew, just a lot of Irish charm and some strange features that will have you itching to play! So grab a pint glass and wait for your first serving of this weird colourful beverage, but will you end up with some cash to go along with your drink, or will you be barred? Let’s find out in our Rainbrew slot game review.


Rainbrew is a strange mix of old and modern design, with the only consistent part of it being the many bright rainbow colours used everywhere. The background to the reels is an out of focus view of the brewery’s front door, while on the reels themselves is a collection of colourful Celtic knots to represent the low-value symbols and a crew of Leprechaun workers to represent the high-value ones. There are also a few other symbols, including a pint of rainbow beer, a pipe emitting rainbow smoke, a leprechaun swilling his brew and a lady leprechaun carrying a barrel on her shoulder. Most of the animation comes from the sidewinder reels top and bottom of the screen, though there is a hearty Irish jig in the background throughout.

This is an unusual looking pokie, but Rainbrew begins to make more sense when you understand it: The bars on the top and bottom of the screen are like sideways reels, so imagine that they form a sort of extra row for the middle three reels. This means two reels at the left and right ends only have three rows, while the middle three have four, creating a 3-4-4-4-3 type arrangement that gives you 243 ways to win. The RTP here is a hair above average, so you’ll be relying on the extra reels (called sidewinder reels by the game) to bring you those big wins. Luckily, they’ll add a few special symbols in some base game spins and hopefully make you rich!


The sidewinder reels are the key to the Rainbrew slot game, so listen up! You get two kinds of wilds in this game, blue and green, and you need the right colour to land on the top or bottom of the screen adjacent to the sidewinder of that colour to trigger wilds on that sidewinder. This can let you build big wild combos to make you money! However, land two scatters next to one of the sidewinders and more will land on them, and if you can get five scatters, you enter the free spins bonus! This grants you up to ten free spins on expanded reels which are now 5×5, with wilds that appear on both sidewinders with every spin. It’s possible in this way to land a complete set of reels full of wilds, which pays 2720x your stake!

CasinoNZ Verdict

Rainbrew is an original and colourful pokie with great graphics, and it gets so bright you might wonder if you’ve had a bit too much brew yourself! The bonuses and original game mechanics are fun and profitable, and while the jackpot could be more significant, we reckon you’ll have a load of fun trying to win it!
