Worked example. Stake 500 coins. The line bet is 500 ÷ 20 = 25. Three Reactor Cores pay 50× the line bet, so that line returns 1,250 coins. Wins on separate lines are added together.
The Live Wire substitutes for every symbol except the Master Switch and appears on all five reels, not just the middle three. It also pays in its own right: three, four or five on a line return 160, 600 and 2,400 times the line bet. Five Live Wires on one line is the largest single win in the game, at 120 times your total bet.
The Master Switch pays wherever it lands, no payline required, and it pays a multiple of your total bet.
| Master Switches | Scatter pay | Free spins |
|---|---|---|
| 3 | 3× total bet | 8 |
| 4 | 15× total bet | 12 |
| 5 or more | 60× total bet | 20 |
Free spins run automatically at the triggering bet and every win inside them is doubled. More switches during the feature add more spins. Runs average around nine spins including retriggers.
This is the mechanic that separates Voltage Rush from a plain twenty-liner. If a paid spin lands exactly two Master Switches and returns nothing, reel five respins on its own, for free. You get a second look at the free-spin trigger on the spins that would otherwise be dead. It does not fire during free spins and it never costs a coin.
The respin is already included in the published 96.5% figure — the simulator plays it exactly as the game does.
Spark, Surge, Overload and Powergrid sit above the reels and grow with every paid spin. Any paid spin can drop one at random; there is no combination to chase. Bet size scales the chance proportionally up to a cap. A dropped meter resets to its seed value and starts climbing again.
Jackpots pay coins. Like every other win here they have no cash value and cannot be withdrawn, transferred or exchanged.

Each reel carries a fixed strip of symbols. Every spin selects an independent random starting position on each strip using the browser's random number generator and displays three consecutive symbols. Earlier spins have no bearing on later ones: there is no due win, no hot streak and nothing that reacts to your balance or session length.
The strips, the paytable and the evaluation code all ship with the page in /assets/js/slot.js. If you want
to audit the maths rather than take our word for it, read the file.
A malfunction voids all plays and pays. Coins hold no value, so nothing is owed in either direction. Clearing browser storage resets balance, level and statistics to a fresh start.
No account, no card, no download. Just twenty lines and a spin button.
