The game uses a very high volatility model, a 96% RTP and stakes from 0.20 to 50.00. A demo version is available for players who want to play for free and practice before playing for real money.
The slot combines Irish-themed symbols such as four-leaf clovers, horseshoes, mushrooms and beer mugs with playing card icons. Its main features include a collect symbol that appears on reels 1 and 6, fixed cash values and three jackpots: Minor, Major and Mega. The Mega Jackpot is not available in the base game and becomes active in the Rainbow Rush bonus.
Three or more scatter symbols trigger a bonus choice between up to 30 free spins or 7 Lucky Rainbow Rush spins. Free spins can include wild multipliers of 2x, 3x or 5x, while the Rainbow Rush bonus guarantees at least one collect symbol on each spin. A bonus buy option is also offered for 4, 5 or 6 scatter activations at set costs based on the stake.
