Extreme Volatility Warning

Extreme

Book of Shadows carries Nolimit City's highest volatility rating. Expect long dry spells punctuated by massive win potential. The 30,338x maximum payout occurs approximately once every 10 billion spins, with the Golden symbol expansion mechanic during Free Spins creating the path to five-figure multipliers when a full grid of premium symbols lands.

Witchcraft Features That Deliver

Four distinct bonus mechanics work in tandem to push the RTP ceiling to 96.43% and unlock the path to 30,338x maximum multiplier.

Shadow Rows

Activating additional rows above the standard 3-row grid adds 5 win lines per row. Four Shadow Rows deliver 15 paylines at 1.5x base bet per spin; five Shadow Rows unlock all 20 paylines at 2x base bet.

How to Play Book of Shadows

1

Set Your Bet

Choose between €0.10 and €100 per spin from the bet selector. Each activated Shadow Row multiplies your base bet: 4 rows cost 1.5x, 5 rows cost 2x.

2

Activate Shadow Rows

Click the upward arrow above the reels to add extra rows. Start with 3 rows (10 paylines), expand to 4 rows (15 paylines), or max out at 5 rows (20 paylines) for the highest RTP of 96.19%.

3

Spin the Reels

Hit the large spin button or enable autoplay for consecutive spins. Wins pay left to right across active paylines when matching symbols land on adjacent reels starting from reel one.

4

Trigger Free Spins

Land 3 or more Book of Shadows scatter symbols anywhere on the reels to activate Free Spins. You'll receive 6-14 spins depending on your Shadow Row count, with one symbol chosen as the Golden expanding symbol.

5

Gamble or Collect

After any win, choose to collect or gamble. The 50/50 gamble doubles your win if you guess the correct card colour. Alternatively, spin the Wheel of Bonus when wins are below 60x to potentially convert cash into Free Spins.

Frequently Asked Questions

The maximum win is 30,338x your total bet. This occurs approximately once every 10 billion spins according to Nolimit City's simulation.
