Our editorial rating for slots, computed the same way for every game from the figures on this page: the return (its top and its lowest configuration), the top win, whether that win rewards the game's volatility, the depth of its features, and how much of its data the studio publishes itself. Where a figure is not available, that part is left out rather than guessed. It rates the game, not a casino or the studio, and it is not a prediction of what you will win.
What the figures say about Bloody Mary: Pray for Prey.
Our reading
Peter & Sons publishes 96.37% for Bloody Mary: Pray for Prey, and SlotCatalog's 96.4% is that figure rounded. BigWinBoard lists 96.10%, 94% and 92% instead, which the studio does not publish and no source explains, so we record only the studio's return and price no gap.
The ways count is disputed. The studio's own page gives 3,125 ways in its specification table and 259 in its description, and the third-party sources split the same way; we will not publish a figure until Peter & Sons confirms one. What is settled is the 5×5 grid and the Connected Ways rule: wins run from the leftmost reel across adjacent reels.
The studio rates it very high volatility, against high from BigWinBoard and SlotCatalog on a coarser scale, and the 30,000× maximum is matched by both. Before each spin, random positions are highlighted with wild multipliers starting at 1×, 2× or 3×; in Super Free Spins they start at 2× and double on each activation, through 4×, 8×, 16×, 32× and beyond. Peter & Sons gives a hit frequency of 31.17%, about one spin in three.
Three or more Golden Key scatters give 7 free spins, and Super Free Spins need at least one Red Key super scatter among them. BigWinBoard prices the buys at 100× and 250× the bet, costs the studio does not publish. Peter & Sons gives the maximum stake as €200; both third parties show 30, which may reflect a casino or demo set-up, so we use the studio's figure.

Where the sources disagree
- Paylines / ways: Peter & Sons (official, spec table) 3125 Ways; Peter & Sons (official, description) 259 ways; SlotCatalog 3125; BigWinBoard 259. Not settled, so not shown as a single figure.
The sources do not agree, so we show all of them.
The studio's own page is read first. Third-party databases are research sources: we name them, and do not link to them. A studio can supply a game in more than one return configuration, and the casino chooses one. A higher figure at one source and a lower one at another usually means they read different configurations, not that one is wrong.
What an hour of this game is expected to cost.
That is the maths, not a prediction — a single session can end far above or below it.

What people ask about this game.
The sources we read list 96.37%. The return that applies to you is the one printed in the game rules at your casino.
30,000× the stake.
Very High. Higher volatility means longer dry runs between wins and bigger swings in a session.
Because a studio can ship several configurations and each casino chooses one. A review that quotes a single figure is quoting one configuration.
