Game mechanics

Base game

Expanding symbols:

  • Before the bonus round, a random expanding symbol is selected.

  • The symbol expands to cover the entire reel regardless of its position.

  • Payouts can occur on any positions, not necessarily on a payline.

  • Combinations can occur on all 5 reels simultaneously.

Wild symbol (Zombie Zubarev):

  • Substitutes for all symbols except Scatter.

  • 3/4/5-of-a-kind: x50 / x200 / x750.

  • Can appear on reels 2, 3, 4.

Scatter (Book of the Dead):

  • Triggers free spins: 3/4/5 Scatters = 10/15/20 free spins.

  • Appears on reels 1, 3, 5.

  • Payouts: x2 / x20 / x200 for 3/4/5 symbols.

If you compare Winspinity’s author releases and want to check a Zubarev-themed slot in a similar style, take a look at the ZUBAREFFF TV slot — it has a different vibe, but it’s also built around bonus scenarios and a bold presentation.

Hit Frequency Analysis

  • Any win: 23.4% of spins

  • Win > x10: 4.2% of spins

  • Win > x100: 0.15% of spins

  • Bonus round: 0.83% of spins (~1/120)

  • Rare but big payouts (x500+)

  • Bankroll needed: at least 200–300 bets

  • Not suitable for conservative play

Bankroll management strategies

Conservative (Low Risk)

  • Bet: 0.50 AZN (0.33% of bankroll)

  • Target spins: 300

  • Stop-loss: -50 AZN

  • Take-profit: +50 AZN (33%)

  • Bankroll: 250 AZN

  • Bet: 2 AZN

Parameters:

  • Bankroll: 500 AZN

  • Bet: 10–25 AZN (2–5%)

Comments from Alexander Zubarev

"Book of Zombies is my hardcore slot for those who love risk. High volatility means you can spin 100 times for nothing, and then boom — x2000 in the bonus. Personally, I caught x4800 with an expanding Wild."

"The slot’s signature feature is expanding symbols. When a premium symbol locks on all five reels, it’s just insane. I saw a x8100 win on stream — a guy bet 5 AZN and took more than 40k."

"The main rule of Book of Zombies is: don’t chase losses. This slot pays in waves. You hit a bonus, take profit — and leave. Try to grind it back — you’ll dump double."

Player reviews (verified)

Nijat R., 36, Baku ★★★★★
VIP player | Verified by administration
"Book of Zombies is an insanely tough slot, but that’s exactly why I love it. I play 5–10 AZN bets. In a year I caught three big wins: x1840, x960, and x3200. The last one was with an expanding Zubarev in the bonus — 32,000 manats from a 10 bet. Withdrawal to ABB in 2 hours."

Aynur M., 29, Ganja ★★★★☆
Player 7 months | Verified
"The volatility is truly high, but the 96.9% RTP is noticeable. I follow a strategy: 150 spins at 1 AZN; if the bonus doesn’t hit, I stop. Over 7 months I’m up 340 manats. My biggest bonus paid x670."

Rustam S., 43, Sumgait ★★★★★
High-roller | Verified
"One of the best high-volatility slots on the market. I bet 20–50 AZN, hunting the expanding Wild. Stats over 5 months: 28 bonus rounds, average win x67, max x2100 (105,000 AZN). 15% cashback on VIP Gold status helps a lot."
