Features
9.4
The feature suite is packed with innovation. Between Shadow Rows, Lucky Locks, Wheel of Bonus gambling, and expanding Free Spins symbols, Nolimit City elevated traditional “Book” mechanics into a versatile, high-powered slot experience.
Book of Shadows Slot Features – Detailed Overview
In this Book of Shadows slot, players can adjust rows and lock reels to customize volatility. Compared to standard slots, its expanding-grid setup and tactical bonus options offer unmatched control over payout potential.
Shadow Rows
Shadow Rows allow players to expand the default 5×3 grid (10 paylines) up to 5×4 (15 paylines) or 5×5 (20 paylines). Expanding the grid increases your base bet amount but significantly improves your hit frequency and expands your chances of landing Scatter symbols.

Lucky Locks
After any base game spin, players can choose to lock up to 4 individual reels in place while re-spinning the remaining reels for an adjusted cost. This feature is ideal when landing two Scatter symbols, giving you a targeted shot at triggering the main bonus feature.
Free Spins with Golden Expanding Symbols
Landing 3 or more Book Scatter symbols triggers 10 Free Spins. Before the round starts, a random special symbol is chosen to become a Golden Expanding Symbol. If you are unhappy with the selected symbol, you get one free reshuffle. Golden symbols expand to cover entire reels whenever enough land to form a payout.
Wheel of Bonus & 50/50 Gamble
After any winning spin, players can gamble their winnings for a chance to trigger 10 Free Spins on the Wheel of Bonus, or play a classic 50/50 card gamble to double their payout up to a set threshold.
Book of Shadows Bonus Buy Options
Players can purchase direct entry into the Free Spins round using the Nolimit Booster menu:
- 3 Shadow Rows (10 Paylines): Costs 60x your bet. Grants 10 Free Spins played on a 5×3 reel layout with an active RTP of 96.43%.
