Grid / Payline Setup
This slot starts at 5×3 with 10 paylines, but you unlock extra rows from the menu. Shadow Rows feature lets you flip to 5×4 (15 paylines) or 5×5 (20 paylines) – each costs more per spin and nudges the RTP up slightly. The trade-off is real: base game feels flat until you commit to the bigger grid.
Lucky Locks – Lock / Spin
Lock up to 4 reels after any spin, then spin only the unlocked ones. Lock a scatter and hope for a third? It costs extra – the price scales with what you’ve locked and the symbols on those reels. Land 2 book scatters on locked reels, spin reel 5, hit the third scatter: bonus triggered. The mechanic is sharp but expensive if the locked symbols are premium.
Free Spins Trigger / Payouts
Land 3+ book scatters anywhere in one spin to trigger free spins. The spin count depends on your active grid:
| Grid | Paylines | Free Spins |
|---|---|---|
| 5×3 | 10 | 14 |
| 5×4 | 15 | 12 |
| 5×5 | 20 | 10 |
Before the feature starts, one symbol is chosen as the Golden symbol. It expands to cover full reels – wins don’t need to be adjacent. Land 5 stacked goth girl reels and you pocket 10,000x your stake. Retrigger by landing 3+ scatters again during the round.
Bonus Buy Menu
Can’t wait for the scatter trigger? Buy free spins directly. Cost scales with grid size:
| Feature | Cost | Spins & Grid |
|---|---|---|
| Bonus Buy (3 rows) | 60x stake | 10 free spins / 10 paylines |
| Bonus Buy (4 rows) | 90x stake | 12 free spins / 15 paylines |
| Bonus Buy (5 rows) | 120x stake | 10 free spins / 20 paylines |
Not available for UK players.
Gamble Features – Double or Nothing / Wheel of Bonus
After any win (base or bonus), gamble it. Pick red or black on a card flip – correct guess doubles your win. Chain up to 5 gambles in a row, but your total can’t exceed €500,000.
The Wheel of Bonus is the outlier: gamble to win the free spins bonus round itself, not just cash. A pentagram wheel spins with a red segment. The bigger your bet, the larger that red segment grows – your odds of landing free spins improve with stake size. You can bet up to 60x your stake on this gamble. Win and you trigger 10 free spins immediately.
Paytable / Symbol Payouts
Book scatter / wild is the premium symbol. Goth girl ranks second. Both need only 2 on a payline to pay. Low-value royals need 3. The 5 regular premium symbols pay between 500x and 50x your stake – solid floor for a very high volatility game.
RTP / Volatility / Hit Frequency
The headline 96.19% is the full-grid default. Volatility stays very high across all setups. Free spins trigger roughly every 150 spins on average.
Customizable RTP ranges mean some casinos may offer lower tiers – check operator settings before you play.
Why This Slot Stands Out
this slot strips away the Ra tomb cliché and drops you in a spooky graveyard. The customizable grid, Lucky Locks reel-locking, and Wheel of Bonus gamble give players real agency – but that freedom comes with a cost. The bonus itself is fairly standard book-slot fare: a chosen expanding symbol, reshuffle option, retriggers. For a game this ambitious on the surface, the feature round feels conventional.
