Shamrock Isle Slot Review

The Leprechaun is the Wild symbol and carries a 2x multiplier. It can turn up on any reel during regular play and in standard size. But only on the first, second, and middle reels in the free spin round. However, it expands to cover the reel. Wilds substitute for all other symbols, except the scatter, and help create winning combinations and double the prize. The wild is the game’s highest-paying symbol. When five of them appear on the payline, the game will pay you 5000x of your line bet.

The scatter icon is a Harp that also can turn up on all five reels. You need to land at least three of them on the reels simultaneously to activate the free spin feature.

Other symbols you find on Shamrock Isle are also Irish-related. Unicorns, pots of gold, four-petal clovers, and stylized playing card symbols nicely enhance the game’s style.

Free Spins

Free spins are triggered when three or more Harp symbols land in the main game. This round has up to 125 free spins depending on the number of harp icons started in the round. The great news is that a 3x multiplier is attached to this feature. Therefore, when you trigger free spins, you can expect massive amounts of money.

Five harps = 125 Free Spins
Four harps = 20 Free Spins
Three harps = 10 Free Spins

Bonus Game

When at least three Pots of Gold symbols appear on the reels in the main game, they activate one of the three bonus mini-games.

Coin Grab

Players must grab coins by moving the mouse as they appear and dragging them into the wallet. However, you have to be quick and grab as many as you can before the leprechaun turns up.
