The game has 4 playing card suits which are the lower paying symbol as well as a selection of objects more traditionally associated with the Egyptian artifacts. You will find a flower, the falcon headed Horus, the black Bastet cat, an obelisk filled with inscriptions and Pharaoh himself. The Pharaoh is the most valuable symbol, awarding 2,500 times your total bet if you manage to land 5 on a payline. All the high paying symbol you just need 2 on a payline to get a winning combination where lower value symbols you need 3 of a kind on a pay line.
The Book is the game's wild, substituting for all other symbols as well as the triggering scatter symbol to activate the free spins feature. Landing 3 books anywhere on the reels award the free spins bonus. Landing 4 or more books does not increase the spins but rather increase the scatter payout as 5 books will award you x200.
Before the free spins start, 1 symbol will be chosen at random to become the special expanding symbol. If you land the scatter symbol anywhere on the reels, it does not need to be on a payline, it expands to cover the entire reel and award a payout. The feature can be retriggered with the same expanding symbol, however as of lately, most book of games now are re-designed and if you re-trigger the bonus game, a different symbol is awarded.
I once had a full line of all the cats, making it close to x1000 win and that was my biggest.
