Wins between 25x and 100x let you gamble your prize for a shot at 12 Free Spins using a color-coded wheel.
- Green = your winning chance.
- Purple = Enhanced Free Spins.
If the gamble fails, you lose the spin reward. Win Exchange is not available if Free Spins have already been activated.
Holy Water Feature
During any base game spin, Holy Water may splash across the middle four reels.
- Any Lady, Gentleman, Maid, or Gardener hit by it turns into a Wild.
- At the beginning, the win multiplier is 1x, and it increases by +1 for each Wild hit that spin.
Multiplier resets after every spin, which helps boost your chances for a bigger payout in the base game.
Scatters
There are two types of Scatter symbols:
- Silver Castle Scatter – appears on reels 1 to 5
- Gold Castle Megascatter – appears only on reel 6
3 or more Scatters = 12 Free Spins, with +3 extra spins for every Scatter beyond the third.
If one of them is a Gold Megascatter, you activate Enhanced Free Spins instead.
Note: Scatters do not appear during the Free Spins round.
Free Spins
At the beginning of a round, the win multiplier starts at 1x and grows by +1 every time a Lady, Gentleman, Maid, or Gardener becomes Wild.
Holy Water is active on every spin during this round.
When the multiplier hits 20x, 40x, and 60x..., you get 6 more Free Spins.
At the end of the round, your total winnings are added to your balance, and normal play resumes.
Megascatter Enhanced Free Spins
This is an upgraded Free Spins mode triggered by the Gold Castle Megascatter.
- The win multiplier starts at 2x instead of 1x.
- It increases by +2 (not just +1) every time a character turns Wild.
