Slot Glossary
33 terms covering Haunted Crypt's 5x3 Tumble engine, Multiplier Wilds (x2-x100 compounding), Electrified Frames +1x growth, Super Free Spins x2-x10 global, and the path to 10,000x.
Autoplay
Spin Haunted Crypt on automatic for a chosen number of rounds. Optional stop conditions: stop on Free Spins trigger, stop on a high-multiplier wild landing, or stop on long tumble chains. Useful because the 3-Tomb scatter trigger sits at roughly 1 in 260 base spins — autoplay grinds dry stretches without manual clicks.
Base Game
Regular spins on the 5×3 grid before Free Spins activates. Wins resolve through 20 Lines left-to-right starting from reel 1, with the Tumble engine chaining cascade wins. Hit frequency around 25%, so one in four base spins forms at least one paying combination. Most session profit comes from Multiplier Wild compounding inside cascades.
Bet Range
$0.20 to $5.00 per spin on Haunted Crypt. Bet covers all 20 paylines on the 5×3 grid. The low max bet ($5) caps high-roller exposure but keeps the slot accessible. Bonus Buy where legal scales with your bet — same proportional value at any stake level.
Bonus Buy (Feature Buy)
Skip base spins and jump straight into Free Spins. Haunted Crypt offers two tiers: standard Free Spins at 100x bet (~80x avg return) or Super Free Spins at 500x bet (~440x avg return, both at 96.51% RTP). Restricted in UK, Netherlands, Germany, and several other regulated markets. Pragmatic Play's bonus-buy distribution.
Cascading Reels (Tumble)
Haunted Crypt's core mechanic. When a line wins, all matching symbols disappear. New symbols drop into the empty positions. The cascade keeps resolving as long as new wins form — one spin can produce four, five, sometimes seven straight tumbles. Each tumble in the chain pays separately. Multiplier Wilds carry their values across the whole cascade.
Crypt Bonus (Free Spins)
Haunted Crypt's primary Free Spins feature. Triggered by 3+ Tomb scatters anywhere on the grid. Awards 10 free spins. Tumble engine stays active. Multiplier Wilds now drop Electrified Frames at their landing positions, and frames persist for the entire round. Retrigger possible if 3+ scatters land during the bonus — adds 5 more spins. Average return: ~80x stake.
Dead Spin
A spin that returns nothing. Haunted Crypt's high volatility produces dead spins around 75% of the time at base — meaning roughly three in four spins return nothing. Even paying spins often return small amounts; the bigger payouts cluster in cascade chains and Free Spins. Base game stretches without features can run 187 spins on average before Free Spins trigger.
Electrified Frames
Haunted Crypt's headline Free Spins mechanic. Active only during Free Spins and Super Free Spins. When a Multiplier Wild lands, it leaves a glowing frame at its grid position. The frame inherits the wild's multiplier and stays locked for the rest of the bonus round. Every subsequent free spin bumps the frame's multiplier by +1x automatically. Land another wild inside an existing frame? The frame absorbs the new value multiplicatively.
Feature Trigger Rate
How often Crypt Bonus activates. Haunted Crypt's 3-Tomb scatter trigger sits at roughly 1 in 260 base spins. Super Free Spins has no natural trigger path — accessible through Bonus Buy at 500x stake only. Combined feature rate (with Bonus Buy access) brings entertainment cycles into the 200-spin range.
Free Spins
Bonus rounds where you don't pay the stake. Haunted Crypt's Crypt Bonus awards 10 spins on a 3-Tomb scatter trigger. Multiplier Wilds drop Electrified Frames that grow +1x per spin throughout the round. Frame stack of three or more: ~18% of bonus rounds. The path to substantial bonus payouts.
Hit Frequency
How often Haunted Crypt lands any winning combination. Base game hit rate sits around 25% — meaning one in four spins returns something. About 35% of paying spins extend into a second tumble or beyond. Long chains (5+ tumbles) appear roughly 1 in 80 spins, providing the biggest base-game payouts when they catch a high-multiplier wild.
Max Win
The absolute maximum a slot can pay on a single round. Haunted Crypt caps at 10,000x. The path runs almost exclusively through Super Free Spins (x10 global multi roll) combined with stacked Electrified Frames at peak multiplier values. Probability ~1 in 95,000 Super FS rounds — extremely rare.
Multiplier Wilds
Haunted Crypt's second core mechanic. Wild symbol landing anywhere on reels 2 through 5 in base game, or any reel during free spins. Each wild carries a multiplier value from x2 up to x100. Two or more wilds active inside the same cascade chain don't add — they multiply. A x5 wild plus a x10 wild during one spin's tumble sequence applies x50 to the line payout.
Paylines
Predefined lines across the reels where matching symbols form a win. Haunted Crypt runs 20 Lines on the 5×3 grid. Lines pay left-to-right starting from reel 1. All 20 lines are always active. Standard density for high-vol Pragmatic designs.
Paytable
The reference chart showing each symbol's payout. Access through the game's info menu. Haunted Crypt's premium symbols (vampire, gothic creatures, golden chalice) pay the most line wins. Mid-tier symbols include horror-themed icons (skull, crypt, blood vial). Card royals (A/K/Q/J/10) fill out the bottom across the 20-line layout.
Persistent Frames
Haunted Crypt's Free Spins multiplier accumulation. Electrified Frames lock in place for the rest of the bonus round once activated. About 1.4 frames active by spin 5 of a free spin round on average. Stack of three or more frames: ~18% of bonus rounds. All five reels framed: less than 0.3%. The +1x per spin growth means later spins matter more than early ones.
RNG (Random Number Generator)
The cryptographic algorithm determining every spin outcome. Pragmatic Play uses BMM Testlabs and GLI-certified RNGs — independently audited for fairness. Each spin in Haunted Crypt is independent of the last; previous wild values or scatter counts have zero influence on future outcomes.
RTP (Return to Player)
The theoretical percentage of wagered money a slot returns over millions of spins. Haunted Crypt runs at 96.51% (top version) — solid for a high-volatility Pragmatic Play release. Watch out, though: some casinos use the 95.51% or 94.51% versions. Always check the info panel before you spin.
Retrigger Mechanic
Haunted Crypt's Free Spins extension. Land 3+ Tomb scatters during the Free Spins round and 5 additional spins are added on top of remaining spins. Persistent Electrified Frames carry through retriggers — already-locked frame multipliers don't reset. Retrigger rate: ~12%. Chained retriggers can stretch a 10-spin round meaningfully.
Scatter (Tomb)
Haunted Crypt's Free Spins trigger symbol. Three or more Tomb scatters anywhere on the grid open the 10-spin Crypt Bonus Free Spins round. Three scatters during the Free Spins round retrigger 5 additional spins. The Tomb symbol is the gateway to all Free Spins triggers — Super Free Spins is buy-only.
Session Variance
The gap between actual results and theoretical RTP. Haunted Crypt's 96.51% RTP and high volatility produce wide session swings. A 500-spin session can return 30% to 250% of stake. Most expected return concentrates in Free Spins triggers — sessions without one tend to track close to a flat loss rate.
Sticky Wild
Haunted Crypt's Multiplier Wilds aren't sticky in the traditional sense — they persist across cascades within a single spin but disappear after the spin ends. The Electrified Frames mechanic in Free Spins is the closest equivalent: frames lock at wild positions for the rest of the round, with auto +1x per-spin growth.
Super Free Spins
Haunted Crypt's premium Free Spins variant. Bonus Buy purchase only — 500x stake. No natural trigger path inside base game. 12 free spins with everything from standard FS plus a global multiplier of x2, x3, x5, or x10 chosen at random per round. The global multi applies to total round winnings, on top of frame and wild values. The only configuration where the 10,000x cap becomes a realistic outcome.
Tumble Engine
Haunted Crypt's cascade resolution system. Powers the cascading wins mechanic — winning symbols vanish, fresh symbols drop into the gaps, and any new wins that form from the new arrangement also pay. The chain continues until no further winning combinations appear. Each tumble is a separate payout opportunity.
Volatility (Variance)
How a slot's payouts are distributed. Haunted Crypt is rated High — meaning long stretches between meaningful wins, punctuated by occasional cascade chains and Free Spins triggers. Bankroll requirement: 500x stake minimum for a realistic shot at riding out the gap between Free Spins triggers.
Wild Compounding Math
Haunted Crypt's multiplier wild interaction. Multiple wilds active inside the same cascade chain multiply (compound), not add. A x5 wild and x10 wild during one spin's tumble chain apply x50 to line payouts on tumbles after both wilds are active. This compounding behavior — combined with the Electrified Frame +1x growth — is what makes the multiplier ladder reach max-win territory.
Pragmatic Play Provider Catalog
Pragmatic Play is a Malta-based provider known for high-volatility slots like Sweet Bonanza, Gates of Olympus, and Sugar Rush. Haunted Crypt (March 2026) sits in their horror-themed catalog. BMM/GLI certification covers their RNG. Distribution is broad — most major regulated markets carry Pragmatic titles with appropriate regional buy-feature limits.
Multiplier Wild Distribution
Haunted Crypt's wild value math. Multiplier values: x2, x3, x5, x10, x25, x50, x100. Average wild value sits around x6. Stacking two average wilds in the same cascade = x36 on the affected line. x50 or higher: about 2% of wilds. x100: less than 0.5%. Pure RNG distribution.
Frame Growth Math
Haunted Crypt's Electrified Frame compounding mechanic. Frame starts at the wild's landing value (x2 - x100). Auto +1x per spin. New wild inside frame: combines values multiplicatively. Average frames active by spin 5: ~1.4. Stack of three or more: ~18% of bonus rounds. The +1x per spin growth means a x5 frame at spin 1 becomes x14 by spin 10.
Super Free Spins Math
Haunted Crypt's Super FS configuration. Cost: 500x stake. 12 spins. Global multiplier rolled per round: x2 (50%), x3 (30%), x5 (15%), x10 (5%). Frame and wild values stack underneath the global multiplier. Hitting the 10,000x cap requires x10 global plus stacked frames — about 1 in 95,000 Super FS rounds.
Loss Rate vs Bonus Buy Cost
Haunted Crypt's buy-feature math. Standard Bonus Buy at 100x stake returns ~80x average — slight expected loss. Super Bonus Buy at 500x stake returns ~440x average — also expected loss, but with higher win potential. About 65% of Super FS rounds return less than the 500x cost. The remaining 35% justify the buy mathematically.
Bonus Buy Restrictions
Some countries ban purchasing bonus rounds. UK prohibits since October 2021. Netherlands and Germany also block. Sweden caps bet sizes during buys. Haunted Crypt's Bonus Buy follows these restrictions. Pragmatic Play distribution routes through licensed operators where buy availability varies by jurisdiction.
Vampire / Horror Symbol Hierarchy
Haunted Crypt's premium symbol order. Top-tier vampire and gothic creature symbols pay the highest line values. Mid-tier horror imagery (skull, crypt, blood vial) fills the middle. Card royals (A/K/Q/J/10) fill the bottom. The premium-tier symbols pay roughly 10x more per line than mid-tier symbols.
