Haunted Crypt — Bonus Features
Wilds on the middle three reels carry x2 to x10, and during free spins each one leaves an electrified frame that grows +1x a spin. Here's how Haunted Crypt assembles its 10,000x ceiling.

Multiplier Wilds
How to Trigger
A wild landing on reel 2, 3 or 4. They do not appear on the outer reels at all.
What Happens
Wilds substitute for every regular symbol except the scatter. In the base game each carries a multiplier between x2 and x10, and the value applies to every winning combination that runs through that position. When two or more multipliers take part in the same win, Pragmatic adds the values together.
Multipliers
x2 to x10 in the base game. Additive, not compounding — x4 plus x6 equals x10.
Strategy
This is the whole of the base game. There is no cascade, no respin and no second mechanic underneath — a spin either lines symbols up through a multiplier wild or it does not. Which is why the frames in free spins matter so much.
| Reels | 2, 3, 4 only |
| Base Multiplier | x2 – x10 |
| Combining | Additive |
| Substitutes For | All but the scatter |
| Paylines | 20, left to right |
Electrified Frames
How to Trigger
Active during free spins only. A frame appears wherever a wild lands.
What Happens
Every wild that hits during the feature leaves an electrified frame at its position. On each subsequent free spin, every existing frame gains +1x. A wild landing directly on a framed position adds a further +1x to that frame. When a wild lands anywhere on the grid, all framed positions convert to wilds for that spin, and their accumulated multipliers apply to any win passing through them.
Multipliers
Frames grow +1x per spin, plus +1x extra when a wild lands on one. Multiple frame multipliers in the same win are added together.
Strategy
Frames set early are worth far more than frames set late, because the +1x growth compounds over the spins that follow. A round that places two or three frames in its first few spins is a different proposition from one that places them at the end.
| Active In | Free spins only |
| Growth | +1x per spin |
| Wild on a Frame | +1x extra |
| Wild Elsewhere | All frames turn wild |
| Combining | Additive |
Free Spins
How to Trigger
Three scatters in a single base-game spin, in either Value or Speed mode.
What Happens
Ten free spins to start. The frame mechanic switches on for the duration: wilds leave frames, frames grow +1x per spin, and a wild landing anywhere converts every framed position to a wild for that spin. Three scatters during the feature retrigger it for five additional spins. The round ends immediately if the 10,000x cap is reached.
Multipliers
Frame values accumulate across the round and are added together where they meet in the same win.
Variants
Speed mode triggers the feature more often and pays less per feature on average than Value mode. Cost per spin and paytable are identical.
Strategy
Most of the game's payout potential sits here — the base game is a straightforward 20-line slot with multiplier wilds and nothing else. Pragmatic does not publish a trigger frequency, so plan the session by bankroll rather than by expected spins.
| Trigger | 3 scatters |
| Spins Awarded | 10 |
| Retrigger | +5 spins |
| Round Ends At | 10,000x |
| Modes | Value / Speed |
Bonus Buy
How to Trigger
Purchased from the base game where the operator and jurisdiction permit it.
What Happens
Two prices. 100x your bet buys the standard free spins round. 500x buys Super Free Spins, where a random general multiplier is applied to each spin on top of the frame values. The game client reports 96.52% on the standard buy and 96.50% on the super version — both within a hundredth of the 96.51% base game.
Multipliers
Standard buy: frame multipliers only. Super Free Spins: a random general multiplier per spin, layered over the frames.
Variants
The base game also carries two special bet options. Super Spin 1 costs 20x and guarantees at least three framed positions on reels 2, 3 and 4. Super Spin 2 costs 100x and highlights at least four, with a general multiplier between x2 and x10 selected each spin. Free spins cannot trigger while either is active.
Strategy
The published RTPs are near-identical across all routes, so the choice is about how you want the variance shaped rather than about value. Buy features are blocked outright in the UK and several other regulated markets.
