Game Content

If you’ve played the Blue Diamond Book, then you have essentially played the Book of the Princess too. Same book different graphics, though the characters and symbols are the same. The only real difference is the Blue Diamond Book feature. OK the background is different, and the music is a little feistier than that of the Book of the Prince, but the game is essentially the same sans Gamble feature.

There is not much to this game, but that is OK as sometimes basic is all you need in a slot. Unless you are looking for a game that isn’t really engaging enough to make anyone’s top ten list, then this is a game that you will likely play once. Unless of course, you drop a massive win, in which case you’d stay a while.

The soundtrack to this game isn’t really a soundtrack, more of a theme that is played throughout the game. What makes it interesting is the tension that the dropping of the scatter symbols offers.

The safer gambling element is missing in this game, and the auto-play is limited. You can’t control your losses, but you can work out how much you could be done at the end of the run. It’s not a good way of keeping track of what you spend in a game.

Game Developer

Spearhead Studios are massive. Not just in the size of what they do, but in what they bring to the iGaming world of slots. Part of the EveryMatrix group, Spearhead have added some memorable games to the fabulous list of Book of… series of games, including Book of Spies Mission X, Book of Souls Remastered, Book of Souls II El Dorado, Book of the King and Book of the Princess.

Bonus Feature

Free Spins

The Blue Diamond Book is built around the classic scatter symbols that you’d normally get with any Book of… slot. Three triggers the Bonus spins and you are then taken to the actual Blue Diamond Book which reveals your Bonus symbol, and the spins begin. You start with 10 free spins.

Prizes in this game are not the biggest we’ve come across, but they are generous, including the bonus rounds. That said, it took us a long time to trigger the free spins through the Book scatter symbols, but the wait was worth it.

Gamble Feature

There is no gamble feature in this game, but there is a pick and click “Booster” feature that offers a shot at a Bonus feature. The rest is just good old-fashioned reels and spins with good graphics and an OK soundtrack.
