Book of the Irish slot review
Book of the Irish is Inspired’s Irish-themed take on the popular book format: five reels, ten paylines and a Book symbol that acts as both wild and scatter. Three or more Books award ten free spins with a special expanding symbol, set to Irish folk music and a cheerful leprechaun.
How Book of the Irish plays
Leprechauns, harps, pots of gold and card symbols fill five reels and three rows, with wins paying across ten lines. The Book substitutes for the other symbols and also pays as a scatter anywhere on the reels.
Three, four or five Books pay two, 20 or 200 times your total stake and start the free spins.
Free spins with an expanding symbol
Three or more Books award ten free spins. Before the round, the Book picks one symbol to be the expanding symbol for the free spins.
When enough of the expanding symbol land for a win, it grows to cover its whole reel, which can connect wins across all ten lines. Inspired’s launch notes also describe a gamble option linked to the free spins; check the game’s help screen for the version you play.
RTP, volatility and top wins
Inspired publishes an RTP of 96.23%. The in-game information panel shows the live figure.
Inspired caps the top win at £250,000.
