How the video slot works

Book of Kings brings us to Egypt, where we’ll find a 5×3 grid set against the backdrop of the Pyramids. Play the game from as little as €0.10 all the way up to a whopping €500. The betting range caters to all kinds of players.

You’ll have to match symbols up from left to right in one of ten different paylines to land a win. Symbols in the game include the standard cards from 10-A plus various Egyptian themed symbols. There’s the Eye of Ra and the Horus, the Egyptian falcon-headed god. Finally, there’s also the Pharaoh and the best paying symbol in the game, the female protagonist.

You’ll also come across two different golden books in the game while playing. First, there’s the standard golden book. This acts as a wild, substituting for other symbols and landing three of them on a spin will unlock ten free spins. The other book is the golden book and snake. This symbol also acts as a wild and if it’s part of the scatter any wins during the bonus round will be tripled.

During the Book of Kings free spins mode, a symbol will be randomly chosen to be an expanding symbol during the round. Every time you land this symbol, it will expand to cover the whole reel, leading to some impressive wins. This bonus round gives you the best chance of landing a big win and the maximum jackpot for the game, which is 15,000x your stake.

Closing Thoughts on Book of Kings

While yet another slot set in the tombs of ancient Egypt may not fill you with excitement, the gameplay certainly will. Book of Kings doesn’t win any originality points for it’s setting and design, opting to go with the classic, Egyptian Explorer looking for buried treasure theme. A lot of the game features may surprise you though, if you’re expecting a typical boring clone, this isn’t it.

We enjoyed Book of Kings a lot, finding that wins were pretty frequent and managed to trigger the bonus rounds a good number of times. The expanding symbol during the round adds something a little more interesting, and the promise of a big win kept us thrilled throughout our time playing the game.
