Slot Glossary
33 terms covering Wrath of Hephaestus's Expanding Wilds (full reel coverage), Extra Wilds random adds, Re-Spin Expanding Wild chains, retriggering Free Spins, and the path to 5,000x.
Autoplay
Spin the reels automatically for a set number of rounds. Wrath of Hephaestus lets you set stop conditions — stop on Free Spins trigger, stop on Re-Spin chain, stop on a single-win threshold. Useful for grinding the ~1 in 220 scatter trigger that opens the Free Spins round.
Base Game
Standard play before Free Spins triggers. Wrath of Hephaestus's base game runs across 20 paylines on the 5x4 grid. Most base value comes from Expanding Wild events (full-reel coverage), Extra Wilds boosting hit frequency, and Re-Spin Expanding Wild chains extending winning rounds.
Buy Feature
Wrath of Hephaestus's direct bonus entry. Costs ~100x stake to enter Free Spins immediately, skipping the natural scatter wait. The bonus runs identically to a triggered round — same 10 spins, same Wild mechanics, same feature multiplier and retrigger rules. RTP holds at 95.78% across both paths.
Cascading Reels (Tumble)
Wrath of Hephaestus doesn't use cascades. Wins resolve once per spin via 20 paylines. The replay action comes from Re-Spin Expanding Wild chains rather than from cascading symbol removal — different mechanic family entirely.
Dead Spin
A spin returning nothing. Wrath of Hephaestus's high volatility produces dead spins around 65-70% of base spins. The math model concentrates payout density into Wild expansion events and Free Spins rather than spreading it across base hits.
Expanding Wilds
Wrath of Hephaestus's headline mechanic. Wild symbols expand to cover the entire reel when they land — turning a single symbol into 4 Wild positions across all 20 paylines. Multiple expanding wilds on different reels can trigger simultaneously, creating massive win potential.
Extra Wilds Feature
Wrath of Hephaestus's mid-spin Wild injection. Random extra wild symbols are added to the reels during specific spins (~1 in 25 base spins). Combined with the expanding mechanic, these additional wilds dramatically increase coverage across the 5x4 grid. Extras can trigger Expanding Wild logic when they land on a reel with an existing Wild.
Feature Multiplier
Wrath of Hephaestus's Free Spins multiplier layer. Applies to all line wins during Free Spins. Stacks with Wild coverage from the base mechanics — combined with multi-reel Expanding Wild events, the feature multiplier is the math piece that lets the slot reach 5,000x.
Feature Trigger Rate
How often Free Spins activates. Wrath of Hephaestus's natural scatter trigger sits at ~1 in 220 base spins (3+ scatters). Buy Feature provides on-demand access for buy-eligible players. Re-Spin chains trigger on most winning spins so they're frequent rather than rare.
Free Spins
Wrath of Hephaestus's main bonus round. Triggered by 3+ scatter symbols. Awards 10 Free Spins on entry. The Wild logic from base play carries over — Expanding Wilds, Extra Wilds, and Re-Spin Expanding Wild all stay active. A feature multiplier layers on top of line wins during the round.
Greek Mythology Theme
Wrath of Hephaestus is built around Hephaestus, the Greek god of fire, metalworking, and the forge. Spinomenal nailed the atmosphere with molten metal, anvils, volcanic visuals, and mythological symbols across the 5x4 grid. The forge sits at the heart of every spin.
Hephaestus (the God)
Wrath of Hephaestus's thematic centerpiece. In Greek mythology, Hephaestus is the god of fire, metalworking, and the forge — son of Zeus and Hera, husband of Aphrodite. The slot's premium symbol and the visual frame around the 5x4 grid: Hephaestus stands beside the anvil while symbols drop in over molten metal.
Hit Frequency
How often a paying combination forms. Wrath of Hephaestus's base hit rate sits around 30-35% — about 1 in 3 spins pays something. Extra Wilds quietly boost effective hit frequency by adding 1-3 wilds to ~4% of base spins, converting some near-miss spins into paying spins.
Max Win
The absolute ceiling per round. Wrath of Hephaestus caps at 5,000x — modest by 2026 standards but reachable through multiple Expanding Wilds landing across the reels during Free Spins, where the enhanced wild mechanics stack with the feature multiplier.
Megaways
A Big Time Gaming licensed mechanic with up to 117,649 ways. Wrath of Hephaestus doesn't use Megaways — uses 20 paylines on a 5x4 grid. Spinomenal has Megaways-licensed titles in their catalog but Wrath of Hephaestus uses standard 20-line math that fits the Expanding Wild mechanic.
Multiplier
A value that multiplies a payout. Wrath of Hephaestus's base game Wilds don't carry internal multipliers — value comes from line coverage. The multiplier layer comes only during Free Spins via the feature multiplier applied to all line wins. The math model favors coverage over multiplier stacks.
Paylines
Predefined lines where matching symbols form a win. Wrath of Hephaestus runs 20 paylines on a 5x4 grid. Lines pay left-to-right starting from reel 1. All 20 lines are always active. The 5×4 grid (4 rows tall) gives Expanding Wilds more vertical coverage than typical 5×3 layouts.
Paytable
Reference chart for symbol payouts. Access through the in-game info menu. Wrath of Hephaestus's premium symbols (Hephaestus deity art, anvil, hammer) pay the most. Mid-tier covers Greek forge imagery (molten metal, fire, tools). Card royals fill the bottom across the 20-line layout.
Re-Spin Expanding Wild
Wrath of Hephaestus's respin chain mechanic. After an Expanding Wild lands during a winning spin, a re-spin triggers automatically. The expanded wild stays locked in place while the remaining reels spin again. Any new wild that lands during the re-spin also expands, and another re-spin can chain.
Retrigger Mechanic
Wrath of Hephaestus's Free Spins extension. Land additional scatter combos during the bonus to retrigger more spins. Retrigger probability inside the bonus sits at ~10-12% per spin. Chained retriggers stack the feature multiplier across an extended round.
RNG (Random Number Generator)
The certified algorithm determining every spin outcome. Spinomenal uses GLI-tested RNGs — independently audited for fairness in regulated markets. Each spin in Wrath of Hephaestus is independent of the last; previous Wild expansions or scatter counts have zero predictive value for future spins.
RTP (Return to Player)
The theoretical percentage of wagered money the slot returns over millions of spins. Wrath of Hephaestus runs at 95.78% on the standard configuration. Spinomenal provides 4 operator settings, so the actual RTP at your casino might differ. Always check the game info screen before you start spinning — some operators run lower configs.
Scatter
A symbol that triggers features regardless of position. Wrath of Hephaestus's scatters trigger Free Spins when 3+ land on the reels. No reel restrictions. Different from regular paying symbols — scatters don't form line wins, they only trigger the Free Spins bonus.
Session Variance
The gap between actual results and theoretical RTP. Wrath of Hephaestus has 95.78% RTP, but a 200-spin session can range from 30% to 250% of wager. High volatility means session swings are wide — most sessions land below RTP, with rare Free Spins triggers and Re-Spin chains providing variance correction.
Spinomenal Provider Catalog
Spinomenal is an Israeli studio with global distribution. Wrath of Hephaestus (2026) sits in their Greek mythology sub-catalog alongside Poseidon, Zeus, and other deity-themed releases. GLI certification covers all titles. Distribution skews EU regulated markets, LatAm, and select Asian operators.
Stake
Your bet per spin. Wrath of Hephaestus ranges from $0.20 to $100. The stake applies uniformly across all 20 paylines. All payout values (line wins, feature multiplier, max win) are quoted as multiples of stake.
Sticky Wild
Wrath of Hephaestus's Re-Spin Expanding Wild lock behavior. Once a Wild expands on a winning spin, it stays locked in place across the Re-Spin while other reels spin again. The lock isn't sticky in the traditional cross-spin sense — it's chain-internal during Re-Spins rather than persistent across separate spins.
Volatility (Variance)
How payouts are distributed. Wrath of Hephaestus is rated High — long stretches between meaningful wins, then concentrated bursts during Wild expansion events and Re-Spin chains. The math model trades hit frequency for cap density, so bankroll planning needs to account for deep dips.
Ways to Win
An alternative to fixed paylines. Wrath of Hephaestus uses 20 paylines, not ways-to-win. The 20-line layout works well with Expanding Wild mechanics because wild coverage on full reels completes specific line patterns rather than dynamic cluster groups.
Wild Symbol
A symbol that substitutes for any regular symbol to complete combinations. Wrath of Hephaestus's wilds substitute for everything except scatters. The Expanding Wild mechanic transforms single Wild symbols into full-reel coverage, which is the engine of every meaningful base game payout.
Win Distribution
How total payouts spread across categories. Wrath of Hephaestus's high-volatility split: Free Spins with feature multiplier ~40% of total RTP, Re-Spin Expanding Wild chains ~25%, base-game Expanding Wild events ~25%, Extra Wilds boost ~10%. The distribution is heavily back-loaded toward Free Spins.
Bonus Buy Restrictions
Some jurisdictions block bonus purchases entirely. UK has prohibited buy features since October 2021. Netherlands also blocks them. Wrath of Hephaestus's 100x Buy Feature is unavailable in those markets — only natural triggers and Re-Spin chains work for affected players.
5×4 Grid with 20 Paylines
Wrath of Hephaestus's grid format. 5 reels × 4 rows = 20 cells. Pays through 20 fixed paylines. The 4-row height (vs typical 5×3 = 15 cells) gives Expanding Wilds more vertical coverage — a single Expanding Wild covers 4 positions on its reel rather than 3, which boosts the per-event win value.
