Bonus Features

Free Spins Bonus Round

This exciting feature contains up to 25 free spins, multipliers and the chance of landing the Jackpot O' Luck itself. The bonus is activated whenever you land at least three leprechauns in any position on the reels.

The playing grid is replaced by fifteen wooden barrels floating in mid-air. Your task is to choose them one by one to reveal rewards. These include a few free spins, multipliers up to the value of five times your bet and letters from the word 'jackpot'.

Your free spins are added up in a small panel at the top right of the screen. Next to it, your highest multiplier is displayed. There's also a Start Free Spins prize that begins your freebies at the level shown in the panel. The bonus can reactivate again if you land another set of leprechauns whilst your free spins are in progress. Only this time, the maximum multiplier increases to six times your stake.
