Shamrock Isle Unified

Each self-respecting developer company must have at least one title dedicated to St. Patrick's Day, and Shamrock Isle by Rival Gaming is just that - a token holiday slot game decorated with Celtic ligature, 4-leaf clovers, and leprechauns. Let's see what it packs under the hood:

  • RTP of 95%;
  • medium volatility;
  • 20 paylines across 5 reels;
  • top award of 5,000 times the bet.

The most common issue with holiday-themed games is how many feel rushed and underdeveloped - obviously, a consequence of haste to meet the calendar deadline. Did Rival Gaming put enough effort into Shamrock Isle to ensure a wholesome and gratifying player experience? Read more of this Shamrock Isle slot review to find out.

Theme & Visuals

You'll know what to expect from the game's graphics before even looking at the slot machine. Yes, the obligatory enchanted forest and mischievous green midgets are there, along with pots of gold - and unicorns, for whatever reason.

What sets the visual efforts apart from other games dedicated to St. Patrick's, though, is how well it all blends into one lovely bundle - no symbols or artwork seems out of place. The artists even took time to blur the background, thus allowing us to focus on the reels and contents.

Basic Gameplay

Even if it's your first encounter with online casino slots ever, it will take about a minute to figure out how everything works - notably due to how intuitive and clean the game's interface feels. As expected, leprechauns act as guides to the rainbow's end - their symbols multiply your payouts by two, and expanding Wilds when Free Spins are active. In a conservative fashion, one or two Scatters, represented by the Magic Harp symbol, will grant you a payout bonus multiplied by the number of lines that are currently active.

Advanced Gameplay

The fun is brought to a different level with three or more Scatters on the playing board, as this triggers the Free Spins feature. You're getting 10 spins with three Harps, 20 with four, and a whopping 125 with five. The game has a different paytable for this mode, so click on the sandwich menu in the bottom left and see what exactly changes.

Bonus rounds are similar to the feature above from the mechanic's standpoint. The only difference is that no matter how many Pot-o-Gold symbols you hit, you'll still get exactly one extra round played with the same bet you had before. It may not sound too impressive, but the point is that you'll see this bonus getting triggered far more often than Free Spins, so make the most out of both.


What is the minimum deposit needed to play Shamrock Isle for real money?

It has just enough variety to stay fresh for several gaming sessions and doesn't try to be what slot machines are not by imposing some ridiculous rules on the players.
