Book of Dead (PlayNGo)

Payline Structure: The game operates on 20 fixed paylines. All 20 lines are active on every spin; you cannot choose to play fewer lines.  Winning Direction: Winning combinations must start from the leftmost reel and pay from left to right on adjacent reels along an active payline.  Payout Priority: Only the highest-winning combination is paid out per individual payline. Simultaneous wins on separate paylines are added together and credited to your balance.  Bet Limits: Minimum and maximum bet parameters are hardcoded into the software (typically ranging from 0.1 to 100 credits per spin), though exact limits may vary depending on the operator's currency settings. Wild Substitutions: The Wild symbol substitutes for all regular paying symbols to form winning lines. It cannot substitute for Gift Coins. Wild Modifiers: When character features trigger, Wilds can be upgraded to Expanding Wilds (via Brumbles) or assigned a random multiplier between 2x and 100x (via Jingles). If both trigger, they combine into expanding multiplier wilds. Mystery Presents: When these land, all Mystery Presents on the board transform into the same matching icon. They can reveal standard symbols, Wilds, or Gift Coins.  Trigger Requirements: The Hold'n Grow feature triggers instantly when 4 or more Gift Coins land in a single spin. The GO COLLECT Meter: If fewer than 4 Gift Coins land, they do not go to waste. They are automatically added to the GO COLLECT meter, which grants a random, mathematical chance to trigger the bonus feature anyway. Grid Expansion: While the base game runs on a 5x4 layout, the Hold'n Grow feature expands the reels dynamically from 5x3 up to a maximum 5x8 grid depending on how many coins are collected. Fixed Jackpots: Gift Coins hold direct monetary values (up to 5x the stake) or one of the fixed jackpots, up to the 1,000x Grand Jackpot.  Malfunction Policy: In compliance with global gaming commissions, any system malfunction voids all plays and payouts. If a spin is disconnected mid-round, the game state is saved on the game server, and the round will resume automatically the next time the game is loaded. Cap on Winnings: The absolute maximum win per game round is capped at 50,000x your total bet. If the cumulative total of a bonus round reaches this figure, the feature immediately terminates and the max payout is awarded.

Key Bonus Features The gameplay revolves around unique cascading and nudging mechanics that can link together for massive combinations: * Mystery Stacks & Nudge & Reveal: Seaweed symbols land on the reels in stacks of four. When they hit, they trigger the Nudge & Reveal feature. With each subsequent spin, the seaweed stacks nudge down by one position, opening up to reveal either matching high/low paying symbols or Golden Shark symbols. * Razor Reveal Feature: If the Mystery Stacks reveal a Golden Shark, those positions transform into individual mini-reels. They spin to award instant bet multipliers (ranging from 1x up to 2,500x) or Sea Mine Scatter symbols. * Free Games (Free Spins): Landing 3 or more Sea Mine Scatters triggers the Free Games feature. During this mode, reels 2 and 4 are automatically filled with Mystery Stacks. A global win multiplier starts at 1x and increases by +1 every single time a Mystery Stack nudges. The free spin round continues indefinitely until no more Mystery Stacks are visible on the grid.
