Book Hotfire RTP and Volatility

The slot’s RTP is 96.1%, while its variance is high.

The distribution of wins in the Book Hotfire is unbalanced, even if the frequency rate is high (29.06%). The slot’s high volatility results from its paytable. For example, the highest-paid five-of-a-kind line is 50 times greater than the lowest-paid one. Free Spins are also volatile, as the slot randomly picks an expanding symbol.

The theoretical return to play is 96.1%, which is an average value for modern games, but be aware that also the lower RTP is possible: 86%, 90.5%, and 94%.


Book Hotfire

The central theme of the slot is Ancient Egypt. You can see classic symbols of the eye, Anubis, eagle, etc. The slot’s graphics look classy, as many elements have golden frames, gems, and jewelry details.

The gaming board looks like a wall in the palace lit by torches’ fire. Fire details are all over the place in the game. For example, symbols from winning lines start burning after the end of the spin. You can also hear a monotonous classic soundtrack.

The symbol’s package of Book Hotfire contain 10 items.

Regular-pay elements and their respective odds are listed below:

  • 10, J, Q: 0.5x, 2.5x, 10x;
  • K, A: 0.5x, 4x, 15x;
  • Eye of Horus, Anubis: 0.5x, 3x, 10x, 75x;
  • Isis (goddess): 0.5x, 4x, 40x, 200x;
  • Golden pharaoh: 1x, 10x, 100x, 500x.

The only special symbol in the game is a book. It acts as both scatter (pays anywhere) and wild (substitutes other elements). Three or more books trigger free spins.
