Blood Club Slot by Peter & Sons

Five locked padlocks sit above the reels, one per column. Each padlock hides a multiplier counter that opens the moment a winning way passes through its reel. From there the counter increments by 1 for every additional win on that reel, and it stays open as long as coins or wins keep landing in the column. One spin with no activity and it resets. So the entire payout loop feeds through one thing - keeping those multipliers alive across consecutive spins while coins stack up underneath them.

Coin symbols land carrying values from 0.25x up to 5000x and become sticky for 3 spins when they appear. A new coin on the same reel resets that counter back to 3. Fill all four positions on a single reel and the column collects - every coin value on that reel pays out, multiplied by whatever the reel's counter has reached. During free spins (3 scatters to enter, no retrigger), the multiplier counters persist across the full round instead of resetting, which is where they climb past x5 or x6 into numbers that actually move the needle. For 100x you can buy 10 free spins directly, or 200x gets a randomized round of 10 to 15 spins where the game picks its own trigger conditions.

Crimson walls, blood pooling on the floor, vampire portraits in ornate frames above the grid - four character symbols painted in dark reds and purples, plus a wild marked with a jagged red W on black. The low symbols are styled as gothic card suits, spades and fleur-de-lis shapes in deep blue and burgundy against the dark metallic reel frame. Golden Bet bumps your stake by 1.2x (not the usual 1.5x you see elsewhere) and increases scatter frequency during base play.
