This is another bright and entertaining release from Habanero, with the audio and visuals delivering everything you would expect of an Irish-themed slot – Leprechauns, Pots-of-Gold, Rainbows, Four-Leaf-Clover and more. The gameplay is fairly straightforward, but the Expanding Wilds and pay-both-ways of the Pots-of-Gold feature add a significant dose of excitement to the base game. The real selling point is that excellent Free Spins Round. A minimum of 13 Free Spins is pretty good for a game of this type, but the top-end 133 Free Spins is truly spectacular! With an above-average RTP rating (at the top two settings), there’s loads of great value fun to be found here.

  • Rainbow Mania is set on a 5x3 grid
  • Payouts are triggered by landing three or more connecting matching symbols on adjacent reels, beginning on reel 1
  • Lucky Horseshoe Wilds may appear on any reel and substitute for all standard symbols to help complete winning lines
  • Wilds also pay out in their own right, at 88.87x the total bet for five

Rainbow Mania Slot Features

Pot of Gold Feature

In addition to the standard icons, Pot of Gold Special Symbols may appear on reels one and five. Whenever they show up, the following effects kick into gear:

  • Pot of Gold on reel one OR reel five: a Leprechaun Wild appears on reel three and expands to cover the whole reel
  • Pot of Gold on reels one AND five: an expanding Leprechaun Wild appears on reels two, three, and four

With the Expanded Wilds in place, all Pot of Gold symbols are replaced by a standard symbol, and wins are calculated. Unlike on a standard spin, where wins pay out only from left to right, Pot of Gold Spins pay both from left to right and from right to left.

Progressive Jackpot

The max win of 2,031x is a little on the low side for a high-volatility release, but there is always the chance that you may land a significantly bigger score thanks to the Progressive Jackpot feature, which may land at random on any spin.

The exact size of this jackpot will vary given its progressive nature, but can quickly reach the tens of thousands.

Free Spins Bonus

Pipe symbols are the Scatters of the game. Land three, four, or five of these anywhere on the reels to be rewarded with 13, 33, or a whopping 133 free spins. Free spins take place on the same set of reels as the base game, but with so many on offer, you don’t really need any additional features to land a decent win.

Pipe Scatters also act as pay-anywhere symbols - all the way up to 533x the total bet for five.

Our Verdict: This is an incredibly generous Free Spins Bonus that Habanero have laid on. Most Free Spins Bonuses in slot games are capped at around 10 free spins, so to have the chance to get 133 free spins is incredible.

Rainbow Mania Slot RTP & Volatility


Variable RTP





Rainbow Mania has a Return to Player (RTP) percentage of 97.28%. The bright colour scheme and cheery vibe may suggest a relaxing experience, but this game falls firmly into the High Volatility category of slots. As such, you should expect a slightly bumpy rainbow ride, with more low-paying wins and dead spins than in a low or medium-volatility release.

Our Verdict: The top-end Return To Player percentage of 97.28% is excellent for an online slot - comparing very favourably with the industry-average RTP of 96%. However, this is a variable RTP, with alternative settings of 96.75%, 94.14%, and 92.30% also available. We always recommend consulting the information section of the game to discover the setting in use at your online casino of choice. High-volatility games also provide a better chance of hitting a big win in a short session.

Rainbow Mania Slot Graphics & Audio


Rainbow Mania delivers exactly what you'd expect from an Irish-themed slot. The reels are set in front of a tranquil wood, with a house that wouldn't look out of place in the Shire from Lord of the Rings, and a colourful rainbow in the background (it would be a bit weird if a game with 'rainbow' in the title didn't have a singe rainbow anywhere in the game).

Slow, calming music plays in the background while you spin, making the slot seem even more wholesome than it did to begin with. The sounds can be turned off by pressing the volume button in the bottom right cornier should you wish to play in silence.

Our Verdict: Rainbow Mania ticks every box for a slot with an Irish theme. There's rainbows, Leprechauns and horseshoes - the simple things you would expect which have been done right.

Habanero has ensured that both desktop players and mobile slot fans are able to seek their pot of gold at the end of this rainbow. All of the gameplay and features remain intact on your small-screen device, whether you are an iOS or Android user.
