How this slot Pays
Four character premium symbols form the pay table, each worth 0.6x to 50x stake for six of a kind. Wild symbols land freely to complete wins. The grid sits quiet and baroque in daylight – blue sky, sunlight streaming through clouds – until the Holy Water feature tears that facade open.
When Holy Water triggers at random in the base game, it smashes onto the grid and converts 2 or more positions holding premium characters into wilds. Each wild transformation adds +1 to a global win multiplier for that spin only. The multiplier resets after the spin completes, and the game returns to normal play.
Holy Water Feature / Trigger / Multiplier Build
The tension builds because you know what’s coming: the bonus round is where the multiplier stops resetting. Land 3+ Silver Castle Scatters anywhere to trigger the regular Free Spins round – you win 12 spins plus 3 extra for each scatter beyond the minimum. If a Gold Castle Scatter is part of the triggering combination, you get the Enhanced Free Spins instead.
In the regular bonus, the multiplier starts at x1 and climbs +1 per wild transformation. In the Enhanced version, it starts at x2 and climbs +2 per transformation. The multiplier never resets across all bonus spins. If it reaches x20, you win an extra 6 spins in either tier. The game plays out inside the castle with a thunderstorm raging – characters shift to vampires, and the pressure mounts with every wild.
Bonus Buy and Win Exchange
Players outside the UK can purchase both bonus tiers directly. The regular Free Spins round costs 70x stake. The Enhanced Free Spins round costs 200x stake.
The Win Exchange feature lets you trade any win of 100x or more for 12 free spins instantly. If you hit between 25x and 99x stake, you can gamble that win on a wheel spin – land green and you win the 12 spins; land red and you lose the entire amount. It’s a sharp tool when the wait feels long.

| Win Exchange (100x+) | Automatic | Trade win for 12 free spins |
| Win Gamble (25-99x) | Optional | Wheel spin: green wins 12 spins, red loses all |
Grid / Paylines / Betting Range
The game runs on 6 reels, 4 rows, and 4,096 ways to win. Minimum bet is 1 (or 0.2 in some markets), maximum bet is 75 (or 15 in restricted regions). High volatility means wins cluster around the bonus, and the base game can feel flat – the bonus is where the slot grows teeth.
RTP and Max Win
Return to Player is fixed at 96.72% with no alternative tiers. The maximum possible win is 61,720x stake – a far-fetched ceiling that requires the Enhanced bonus multiplier to climb hard and premium symbols to land repeatedly. Only the top-tier symbol pays a decent amount in isolation, but the multiplier mechanic is where the real payoff lives.
