Slot Glossary
35 terms covering Jolt Circuit's Re-Jolt voltage retriggers, Stacked Wilds on reels 2-3-4, Lightning Bolt scatter Free Spins, and the path to 5,000x.
Autoplay
Spin the reels automatically for a set number of rounds. Pick how many spins and optional stop conditions (stop on Free Spins trigger, stop on Re-Jolt chain length, stop on balance threshold). Useful for grinding the 1-in-260 scatter trigger that opens Free Spins.
Base Game
Regular gameplay before Free Spins or the pick mini-game activate. Jolt Circuit's base game runs across 20 Lines on the 5×3 grid. High volatility means a meaningful chunk of session profit comes from Re-Jolt chains and Stacked Wild landings on the middle three reels.
Bonus Buy (Feature Buy)
Skip the base game and jump straight into Free Spins. Jolt Circuit offers Bonus Buy at 80x bet (some menus list 100x — check before purchase). RTP holds at 96.10% across natural triggers and the buy-in. UK and Sweden block Bonus Buy by regulation.
Cascading Reels (Tumble)
After a winning combination resolves, winning symbols disappear and new ones drop into place. Jolt Circuit uses a related but distinct mechanic — Re-Jolt — where winning positions stay LOCKED while everything else respins. Different from cascade slots where winners disappear; here they freeze and pay again on each chain step.
Cluster Pays
Jolt Circuit doesn't use cluster pays. Wins resolve through 20 Lines on the 5×3 grid. Cluster pays would require connected groups of matching symbols anywhere; Evoplay keeps the line-win format here with Re-Jolt providing the chain-reaction value escalation.
Dead Spin
A spin that returns absolutely nothing. Jolt Circuit's high volatility produces dead spins around 65-70% of the time at base game. Stretches of 30-50 dead spins between meaningful wins are normal — the trade-off for Re-Jolt chain potential when a hit finally lands.
Evoplay Provider Catalog
Evoplay is a Malta-licensed provider with diverse catalog spanning slots, instant games, table games, and arcade-style releases. Jolt Circuit (March 2026) sits in their neon/electric themed catalog. GLI certification covers all titles. Distribution skews toward European regulated markets and crypto-friendly operators.
Feature Trigger Rate
How often Free Spins activates. Jolt Circuit's lightning-bolt scatter trigger sits at ~1 in 260 base spins for the 3-scatter Free Spins entry. Scatter retriggers during the round add ~12% chance per spin. Combined: budget for 250+ spins between natural feature triggers.
Free Spins
Bonus rounds where you don't pay the stake. Jolt Circuit awards 10 spins on a 3-scatter trigger. Inside the round: every winning combination triggers a guaranteed Re-Jolt, sticky wilds persist round-long, max wild multiplier expands to x100, and a global x2 feature multiplier applies to every win.
Hit Frequency
How often Jolt Circuit lands any winning combination. The hit rate sits around 30-35% — about 1 in 3 spins pays something at base game. Each Re-Jolt chain step that pays counts as additional reward without an extra spin — effective per-spin payout density is higher than raw hit-rate suggests.
Lightning Bolt Scatter
Jolt Circuit's scatter symbol. Land 3+ Lightning Bolts anywhere on the reels for 10 Free Spins. Scatters can land on any of the 5×3 grid positions and don't need to align on a payline. The neon-bolt design is signature Evoplay theming for this electric circuit slot.
Max Win
The absolute maximum a slot can pay on a single round. Jolt Circuit caps at 5,000x. The path runs primarily through long Re-Jolt chains during Free Spins, where sticky wilds with x100 multipliers compound across multiple chain steps. Estimated probability sits around 1 in 1.5-2 million spins.
Max Win Cap
Once Jolt Circuit hits 5,000x, the round ends immediately. The 5,000x cap is moderate for high-vol Evoplay design — sister Evoplay titles range from 2,500x to 10,000x. The cap is structured to fit the Re-Jolt chain mechanic — long chains can compound quickly toward the ceiling.
Megaways
A Big Time Gaming licensed mechanic with up to 117,649 ways to win. Jolt Circuit doesn't use Megaways — uses 20 Lines on a 5×3 grid. Evoplay has Megaways-licensed titles in their catalog but Jolt Circuit stays with the simpler line format that pairs with Re-Jolt mechanics.
Multiplier
A value that multiplies your win. Jolt Circuit's base-game Wilds carry random x2-x25 multipliers. During Free Spins, the cap stretches to x100 and a global x2 feature multiplier applies to every win. Multiple wilds on the same payline multiply together — two x10 wilds produce x100 line multiplier in compound stacking.
Neon Circuit Theme
Jolt Circuit's visual identity. Retro electric arcade aesthetic with neon-lit symbol designs — voltage spikes, lightning bolts, circuit boards, glowing wilds. Built in HTML5, the OLED-friendly visuals sharpen on modern phones and tablets. Theme reinforces the Re-Jolt voltage-spike mechanic visually.
Paylines
Predefined lines across the reels where matching symbols form a win. Jolt Circuit runs on 20 Lines fixed paylines on the 5×3 grid. Lines pay left-to-right starting from reel 1. All 20 lines are always active — you can't reduce the count to lower the stake. Standard density for Evoplay 5×3 layouts.
Paytable
The reference chart showing each symbol's payout for matching combinations. Access through the game's info menu. Jolt Circuit's premium symbols pay the most. Mid-tier symbols include themed circuit imagery. Card royals fill out the bottom across the 20-line layout. Wild substitutes replace any regular pay symbol except scatters.
Pick Bonus Round
Jolt Circuit's pick mini-game. Triggered by 3+ Bonus scatters on the center reel (~1 in 340 spins). Pick from 3-6 cash boxes to reveal multiplied prizes (50x to 2,500x stake) or trigger an additional feature bonus. Average return ~300x. Top reveal odds ~5%.
Re-Jolt Retriggers
Jolt Circuit's headline mechanic. Every winning combination fires a voltage spike that respins non-winning positions while the winning symbols stay locked. New matches trigger another Re-Jolt, and the chain continues until no fresh wins form. Base game chains usually run 2-3 retriggers; during Free Spins, chains of 8-12 hits become reachable.
RNG (Random Number Generator)
The cryptographic algorithm determining every spin outcome. Evoplay uses GLI-certified RNGs — independently audited for fairness in regulated EU markets. Each spin in Jolt Circuit is independent of the last; previous Re-Jolt chain lengths or scatter counts have zero influence on future spin outcomes.
RTP (Return to Player)
The theoretical percentage of wagered money a slot returns over millions of spins. Jolt Circuit runs at 96.10% — at industry standard. Some operators may run lower variants (94.00% or 92.00%) — always verify the exact percentage in the game info screen before spinning. The Buy Feature maintains the same 96.10% configuration.
Scatter
A special symbol that triggers features regardless of payline position. Jolt Circuit's primary scatter is the Lightning Bolt — 3+ trigger Free Spins. Bonus scatters on the center reel trigger the pick mini-game at 3+. Scatters can land anywhere on the 5×3 grid and don't need payline alignment.
Session Variance
The gap between actual results and theoretical RTP. Jolt Circuit has 96.10% RTP, but a 200-spin session can return 30% to 250% of your wager. High volatility means session swings are pronounced — without a Free Spins trigger and Re-Jolt chains, sessions tend to run 50-75% of theoretical RTP.
Stacked Wilds
Jolt Circuit's base-game wild structure. Neon-lit wild symbols stack 2-3 high on reels 2, 3, and 4 only. When a stacked wild lands fully visible (covering all visible row positions on a reel), it locks in place for the next Re-Jolt evaluation. That locked stack can convert a small hit into a screen-clearing chain.
Sticky Wild
A Wild symbol that stays in place across multiple spins. Jolt Circuit's base-game stacked wilds become "sticky" only for the next Re-Jolt evaluation — they don't persist across full spins. During Free Spins, sticky wilds persist for the entire round duration, contributing to long chain potential.
Voltage Spike
Jolt Circuit's thematic naming for the Re-Jolt trigger event. Each winning combination "fires a voltage spike" through the circuit, which is the visual representation of the Re-Jolt respin. Pure flavor — the math is identical to a respin retrigger but the electric theming differentiates Evoplay's design.
Volatility (Variance)
How a slot's payouts are distributed. Jolt Circuit is rated High — meaning longer dry spells with bigger payoff potential. The 30-50 dead-spin droughts at base game are the trade-off for Re-Jolt chain potential. Free Spins variance is meaningfully higher than base game because chain compounding produces outsized single-spin events.
Ways to Win
An alternative to fixed paylines. Jolt Circuit uses 20 Lines fixed paylines, not ways-to-win. Evoplay reserves dynamic-ways formats for select titles in their catalog; Jolt Circuit stays with the classic line layout that pairs cleanly with Re-Jolt chain mechanics.
Wild
A symbol that substitutes for any regular symbol to complete winning combinations. Jolt Circuit's Wilds substitute for everything except scatters. Each Wild carries a hidden multiplier (x2-x25 base, up to x100 in Free Spins). Multi-wild lines multiply together (multiplicative stacking) — different from compound-additive slots.
Win Distribution
How total payouts are spread across different win sizes. High-volatility slots like Jolt Circuit are bonus-heavy — Free Spins with Re-Jolt chains contribute ~50% of total RTP, base-game Re-Jolt chains ~25%, Stacked Wild multiplier alignments ~15%, standard payline wins ~10%. The distribution skews toward bonus rounds and chain reactions.
Re-Jolt Chain Length
Jolt Circuit's key variance metric. Average base-game chain runs 2-3 Re-Jolts before exhaustion. Free Spins chains average 5-7 with a long tail toward 8-12 on hot rounds. Each Re-Jolt is independent — RNG-driven from the locked state. Chain length distribution is more important than hit frequency for tracking session value.
Bonus Buy Restrictions
Some countries ban purchasing bonus rounds. UK prohibits since October 2021. Sweden caps bet sizes during buys. Jolt Circuit's 80x Bonus Buy follows these restrictions. Evoplay's distribution skews toward markets where buy availability varies. The 80x cost is moderate — sister Evoplay titles range from 60x to 200x.
Neon Circuit Symbol Hierarchy
Jolt Circuit's premium symbol order. Premium 1 (top tier — typically the headline neon icon) pays the highest line values. Premium 2 second. Mid-tier circuit imagery fills the middle. Card royals form the bottom across the 20-line layout. The premium-tier symbols pay roughly 5-10x more per line than mid-tier symbols.
5×3 Grid with 20 Paylines
Jolt Circuit's grid format. 5 reels × 3 rows = 15 cells. Pays through 20 fixed paylines — moderate density. The 5×3 layout is the most common slot format ever. Evoplay's design philosophy keeps the grid simple while concentrating innovation in the Re-Jolt chain mechanic and Stacked Wilds on the middle three reels.
