How do the free spins work?
- Trigger: 3 or more Books anywhere start 10 free spins.
- Expanding symbol: one symbol is picked at random before the spins start. When it lands, it expands to fill its reel and pays on any reels, even ones that are not next to each other.
- Retrigger: 3 or more Books during the round give more free spins.
The Book also pays on its own: 3, 4 or 5 Books pay 2x, 20x or 200x your total bet.
Book of Atem paytable
| Symbol | 2 | 4 | 5 |
|---|---|---|---|
| Pharaoh | 1x | 100x | 500x |
Payouts are multiples of your total bet. The falcon pays 200x for 5, and 5 Books also pay 200x. Sources disagree on the Pharaoh’s 3-of-a-kind prize, so we leave it out.

| Layout | 5×3, 10 lines | 5×3, 10 lines |
| RTP | 96.45% | 93.5% |

The WowPot version shares its jackpot network with Wheel of Wishes. Part of every bet funds the jackpots, which is why its RTP is lower.
