It’s not our job to come up with new names for slots. We are forever grateful for that because the pool of available names is getting ever smaller. Hence we have a title like Rainbrew, which is an Irish-themed game, though you wouldn’t immediately know that (though it does rain quite a lot in Ireland).

These games keep coming even in 2020, though this one was released in 2018, and are enduringly popular. Generally, they stack together with a load of Irish and Irish-perceived stereotypes, here it’s leprechauns, beer, the colour green, and Celtic knots and typefaces, and stick a fairly hard-core gambling game on top.

It’s a traditional and retro style usually, but JustForTheWin have certainly done a bit to jazz up the game here with a big-screen look, complete with bubbling pipes, and a nice, modern control panel.

There are wilds and a sidewinder feature in the base game, and the main feature is a free spins round. A gentle acoustic folk tune plays in the background as a very nice set of symbols spins round, so you could easily chill out for a while playing this game.

But should you go to the Leprechaun’s Brewery? (Not a question we thought we’d be asking today!)

The Game

Rainbrew slot

The control set for Rainbrew is very standard and in the modern style hides a lot behind other buttons for a mobile-friendly, minimal screen.

The spin button is at the bottom right of the screen, and above it, a coin symbol opens up the sliding scale bet controls. Above that is a menu button to access the other options, including the pay table, sound control, and speed spin.

The pay table opens with Celtic-knots, all of which pay .4, .8 and 2-times stake.

  • A pipe pays 0.8, 1.5, and 4-times stake.
  • A beer mug pays 1, 2, and 5-times stake.
  • A barrel pays 1.2, 3, and 6-times stake.
  • The leprechaun woman pays 1.5, 4, and 7-times stake, and the leprechaun man pays 2, 5, and 8-times stake.


There are wilds too. A regular wild with a purple diamond, a top wild with a blue diamond, and a bottom wild with a green diamond.

Regular wilds appear only on the horizontal reels above and below the main reel set. Top wilds appear on regular reel 4 and on the top horizontal reel. Bottom wilds appear on regular reel 4 and the bottom reel.

When one of those appear they activate the corresponding reels, giving you extra wilds and extra ways to win.

Free spins are triggered via the game logo.

Three logos = 6 free spins and 4 gives you 10. Both horizontal reels are in play during the feature, but there are no wilds or free spins symbols on the regulation reels. Instead, wilds that match on the top and bottom reel stack to turn a whole reel wild in between them.

The Verdict

We sometimes have a go at Irish-themed games for being clichéd. Because they are.

However here the developer has done the work to go beyond the surface and deliver some really great innovative gameplay, plus a decent little twist on the game. Even the music is less offensive than is often the case for these titles.

Rainbrew is familiar yet nicely original which seems like a good mix to us, and the gameplay innovations are likely to keep you coming back to keep looking for that winning pint.
