What are Shadow Rows?
Shadow Rows let you play on 4 or 5 rows instead of 3. Four rows give 15 lines and cost 1.5x your base bet; five rows give 20 lines and cost 2x. The RTP rises a little with each row, from 96.01% to 96.19%.
| Rows | Paylines | Cost | RTP |
|---|---|---|---|
| 3 | 10 | 1x | 96.01% |
| 4 | 15 | 1.5x | 96.07% |
| 5 | 20 | 2x | 96.19% |
How do the free spins work?
Three or more books start the free spins. One symbol is picked at random to be the expanding symbol, and you can reshuffle it once. During the round it fills its whole reel and pays on any reels, not only next to each other. Three more books retrigger the round.
The number of free spins depends on your row setting: sources agree it changes with the rows, and the bonus buy always gives 10.
Book of Shadows vs Book of Dead
| Feature | Book of Shadows | Book of Dead |
|---|---|---|
| Provider | Nolimit City | Play’n GO |
| Released | August 2020 | January 2016 |
| Layout | 5×3 to 5×5, 10 to 20 lines | 5×3, 10 lines |
| RTP | 96.01% to 96.19% | 96.21% |

The free spins work the same way, but Book of Shadows adds extra rows, a reshuffle and a bonus buy option, and its cap is about six times higher. Book of Dead is the calmer classic.
Tips for playing Book of Shadows
- Extra rows raise your stake by up to 2x, so lower the base bet if you switch them on.
- Free spins come about once every 150 spins on average, so expect long dry spells at extreme volatility.
- There is a gamble after wins: a red or black pick, and a wheel that can turn a small win into free spins. Skip it if you want to keep your balance steady.
- Older versions also had Lucky Locks, a paid respin with locked reels. One source says Nolimit City has removed it, so check the game rules at your casino.

Online gambling laws differ from country to country, and in some places it is restricted or not permitted at all. Check that online gambling is legal where you live and that the casino accepts players from your country. You must be 18 or older (or the legal gambling age in your country, if higher). Only gamble with money you can afford to lose.
