Land 3, 4, or 5 Book (Scatter) symbols anywhere on the reels during a single base-game spin, and you receive:
- 3 Books: 10 Free Spins + 2x total stake
- 4 Books: 10 Free Spins + 20x total stake
- 5 Books: 10 Free Spins + 200x total stake
Before the free spins begin, the game randomly selects one symbol from the regular paytable to act as the Special Expanding Symbol for the entire round. This could be Rich Wilde, the Pharaoh, Anubis, Horus, or any of the card symbols (A, K, Q, J, 10).
Here is where it gets interesting. When the chosen symbol appears on a reel and can form part of a winning combination on an active payline, it expands to cover all three positions on that reel. The expanded symbols do not need to appear on adjacent reels to create a win. They only need to sit on an active payline. So if Rich Wilde is selected and appears on reels 1, 3, and 5, each of those reels fills completely, and wins are calculated across every active line.
The maths behind this is what gives Book of Dead its extreme win potential. If Rich Wilde fills all 5 reels, every one of the 10 paylines pays 5,000 coins. That is 50,000 coins per spin. Across 10 free spins (or more with retriggers), the cumulative total can reach the 250,000-coin game ceiling.
Even if a lower-value symbol like "A" is selected, the frequency of its appearance on the reels is higher, compensating for the smaller per-line payout with more consistent multi-reel coverage. This balance between high-value/rare and low-value/frequent expanding symbols is what makes the free spins round consistently engaging regardless of which symbol is chosen.
Retriggers are possible too. Landing 3 or more additional Book Scatters during free spins awards another 10 free spins. There is no cap on retriggers, though the probability of repeated retriggers is extremely low.
