Book of the Irish is an online slot developed by Inspired Gaming. It’s a high-volatility game with five reels, 10 fixed paylines and an RTP of 96.23%. Based on an Irish theme the game features a combined Wild/Scatter symbol and Free Spins with a Special Expanding Symbol.


Think of an Irish themed slot, and it’s usually Rainbow Riches that comes to mind. It’s a franchise that has spawned plenty of spinoff games, including the exciting Rainbow Riches Pick and Mix slot, and one that has a huge online following.

But Inspired Gaming decided on a rather different route when they began developing Book of the Irish. They turned to the ‘Book of’ series of games, most of which are based on Ancient Egyptian or Mayan themes. In fact, we think this particular game must be the very first Irish-themed Book of clone, making us wonder what took developers so long to hit on this formula!

Theme, Graphics & Soundtrack

Leprechauns guarding their pots of gold make the ideal subject for an online slots game, which is why there are so many titles in this genre. And Inspired Gaming certainly haven’t let the side down with this impressive-looking game. A cheeky leprechaun features on the reels, along with pots of gold, green shoes and colourful toadstools. There’s a jaunty theme tune that adds to the atmosphere, making for fun and immersive gameplay.

Book of the Irish Bonus Features & Free Spins

As is always the case in Book Of slots games, the Book icon serves a dual purpose. It’s both the Wild and the Scatter, so it’s incredibly valuable. As a Wild, it can substitute for all other game symbols, helping you to land winning combinations and increasing the size of your balance.

As a Scatter symbol, the book icon needs to appear in at least three positions on the reels to activate the bonus round. Now you’ll be awarded 10 Free Spins, but before they can start, there’s a Special Expanding Symbol to be chosen. The book flips through all of the symbols on the paytable, choosing one at random to help you achieve more impressive wins. Each time the chosen symbol lands on the reels, it expands to cover the entire reel when that can result in a win for you. And because the Special Expanding Symbol pays like a Scatter, you’ll receive payouts for landing three or more in any positions on the reels!

There’s also an optional Gamble feature in which you could double your win or win Free Spins. Spin the reel and land within a green section for a win. If you land in a red section, you return to the game minus your latest win.

Overall Review/Our Verdict

Fans of Irish-themed games will enjoy playing this Inspired Gaming slot. The popular ‘Book of’ gaming mechanics will also attract plenty of new fans keen to explore another clone in the series. Smooth gameplay, interesting graphics and a complementary soundtrack that reinforces the theme all add extra touches of magic to a game that we think will be hugely popular with players of all types.

Our one note of caution is to keep a watchful eye on your balance as you play. This is a highly volatile game, so penny slots players could find themselves out of pocket astonishingly quickly. We recommend taking the game for a few hundred spins in demo mode, as this should give you a good idea of how your real funds might perform if you decide to chance your luck at an online casino.
