What to check first in the demo
To start, look at what size the wilds land in. On reels 2-5, a 1×4 expanding wild comes with a multiplier of up to 8x, and on reels 3-4, a 2×4 flame wild comes with a multiplier of up to 64x. Base game wins land about once every 3.32 spins on average.
Feature highlights
When a hook symbol lands on reels 1 and 6, all high-paying symbols on the same row turn into 1×1 wilds, and the hook itself changes into that symbol. When 3 scatters land on reels 2-5, you get 6 free spins, plus 2 more for each additional scatter. If 3 scatters and a super scatter appear together, you enter Super Free Spins, where 2 hooks are guaranteed in the puzzle and in free spins.
Playing to the volatility
Volatility is medium, and free spins come about once every 214 spins on average. Before free spins, a puzzle respin plays first, which sets the minimum wild multiplier for free spins and can add extra spins. Completing the whole puzzle pays the max win instantly. In the end, the puzzle result decides how weighty the free spins are, so watch how the puzzle stage ends several times in the demo.
Bonus buy verdict
Bonus buy comes in two options, 75x and 150x. Ante bet is an option that doubles your bet to help you reach the bonus. It’s a good idea to buy the 75x option a few times, check how much the puzzle results vary, and then decide how you want to actually play.
Summary
Its signature is a layered structure where expanding wilds, hooks, and puzzle respins connect. The chance of hitting the 10,000x max win is about 1 in 1.23 million, which is relatively less rare than among games with a similar max win. It suits players who like horror themes and staged bonuses. It’s among the Pragmatic Play slots with more bonus stages.
