This colourful game has 17 paylines, high volatility, an RTP of approximately 97.79%, and a max win of 2031x your stake. Rainbow Mania is available at our top recommended online casinos. Learn more about this delightful slot and generous bonus offers in our in-depth CasinoWow review.

Theme, Soundtrack, and Symbols

This Habanero online slot hit the Saint Patrick's Day brief with colourful images, Irish symbols, and folklore music. The Irish Leprechaun is the main character and shows up during the expanding wilds feature during the free game feature.

While some may find the relaxing Irish ditty too laid back, the exhilarating sound effects enhance the traditional St Patrick's Day mood. The tune accelerates during the bonus game feature, which creates the expectation of big wins!

The Golden Horseshoe and Leprechaun are wild symbols and substitutes for all symbols except the scatter. The scatter is the Smoking Pipe and can only appear during the base game. Other symbols include bells, horseshoes, four-leaf clovers, and harps.

Game Mechanics

Rainbow Mania has high volatility and an RTP of 92.30% to 97.98%, higher than the industry standard. Seventeen paylines can reward both ways, and the maximum win is 2,031x your bet.

Special Features

Get ready for expanding wilds, pots of gold, and bonus games! Rainbow Mania's special features award both ways, increasing the chances of big and mega wins!

Free Spins

In Rainbow Mania, the Pipe Scatter symbol only appears during the base game and serves to trigger the Pot of Gold feature. Players get 13 free spins in this bonus game, from 3x to 533x their stake.

Pot of Gold

Landing three or more scatters will trigger the Bonus Game feature, awarding players 13 free games. Here the jolly dancing Leprechaun Wild can help you uncover pots of gold. Players can expect Big Win and Mega Win rewards during this feature.

Expanding Wilds

During the free game feature, the Pot of Gold Symbols will trigger the Leprechaun Expanding Wild feature up to 3 centre reels. The symbol can appear on the first or fifth reels, rewarding a single expanding wild on the third reel. If you land two pots, the wilds will expand on all three middle reels and pay both ways.

Bonus Buy

Take fate into your own hands and purchase three or more scatter symbols by tapping the Buy Feature button. Three scatters will appear with a 256.50 bet, three to five scatters with a 356.50 bet, and four or five scatters will land with an 858.50 bet.

The Horseshoe Wild symbol can also appear and substitute for all other symbols. The wins are regular-sized and offer three to five symbols of paying, forming combinations on the paylines.

Play 'On The Go'

Rainbow Mania is fully optimised for seamless play on any device. The mobile experience includes high-quality gameplay on tablets and any screen-size smartphone. Download the mobile app on your iOS or Android device or play the slot instantly on your preferred mobile browser while on the go.

CasinoWow Game Verdict

Join the jolly Leprechaun and go on a fun journey with another top-notch game from Habanero. We enjoyed playing Rainbow Mania, especially in the Pot of Gold free games feature with the Irish ditty pacing in the background.

The slot has high-quality graphics and is worth checking out, particularly for those who enjoy a good Saint Patrick's Day-themed slot. Play Rainbow Mania at any of our CasinoWow-recommended Habanero online casinos today!
