Theme and Symbols

Cheerful soundtrack with the river floating down the stem in the background, green fields and small barrel-shaped houses. Not much else needs to be said, it’s the land of Leprechauns.

In case you wish to see more of lucky leprechauns and their touch of gold, make sure to check out our list of Top St Patrick’s Day Themed Slots. Wilds, Scatters, Leprechauns, Four-Leaf Clovers, Horseshoes, Pipes and playing card suits make up for the pay table in this online one-armed bandit.

Betting Options and Features

The game is played across 5 reels, 3 rows and 25 pay lines where stakes range anywhere from 0,25 - 250,00 credits per spin. The title is of medium volatility and has a best odds ratio of 96%.

As noted earlier, the maximum exposure reaches 2,000x the bet and is nowhere near the best potential we’ve seen in Revolver Gaming’ online slots. Nonetheless, it is still a solid number.

Wild Symbol - Appears on reels 2-5 as a substitute for any other symbol in the game with the exception of Free Spins/Jackpot Bonus Scatters.

Jackpot Bonus Feature - In both base and bonus games, the feature is triggered by landing Black Pots on reels 1 and 3 at the same time as one of 4 Jackpot Pots on the final reel. 

This triggers 3 chances to reveal pots with multipliers and in case the respective Jackpot prize reaches the top of the Jackpot meter, players win corresponding Jackpot as well as the sum of all stacked prize pots. There are Mini, Maxi, Major and Grand Jackpots.

Free Spins - It takes 3 Scatters on reels 2, 3 and 4 to activate 8 Free Spins. Each additional Scatter during the feature adds +1 FS to your tally.

What is more, the studio also allows the usage of the Buy Feature, allowing rollers to purchase either Free Spins or Jackpot Bonus Features.

Wrapping Up

Despite not being the first Irish Luck/St Patrick’s Day based game from this studio, Irish Coins for example, the gameplay experience in the Rainbow Stacks online slot should leave none indifferent.

Thanks to 4 Jackpot Prizes, RTP of 96% and wins of up to 2,000x the bet, there’s a bit of something for everyone.
