How to play Circuit Breaker
Tap or click to start: a fuse box prints in, with the MAINS at the top, switches and wires in the middle and a row of terminals at the bottom.
Trace the current from the MAINS down: it follows every solid wire, both ways through a splitter, one way through a switch (where its white arrow points) and nowhere past a dead end. Dashed lines are open contacts.
Flip the switches you need (tap them, or press their number keys) so the current reaches the green BULB and none of the red HAZARDs. GROUND terminals are harmless.
Lock it in with the breaker lever, Enter or Space before the fuse burns down, then get ready for the next panel.
Keep lighting panels: Endless runs until three shorts or blown fuses, Timed until its two-minute clock or the third fuse.
Controls
| Input | Action |
|---|---|
| Touch: tap a switch | Flip it: the current takes its other wire |
| Touch: tap the breaker lever | Lock it in: throw the breaker and send the current through |
| Mouse: click a switch or the lever | The same as a tap |
| Keys 1–7 (top row or numpad) | Flip the switch with that number on the board |
| Enter or Space | Lock it in: throw the breaker |
| P | Pause |
Tips
Read from the top down: follow the current from the MAINS and stop at the first switch that sends it toward a hazard or away from the bulb. That switch is usually part of the fix.
Watch the splitters: a splitter powers both of its wires, so if one of its branches reaches a hazard, the fix has to keep the current away from that splitter altogether.
On the bigger panels, look at the switches that are not powered yet: later flips often set a switch further down for the moment an earlier flip sends the current to it.
Lock it in as soon as you are sure: the fuse bonus pays for every bit of fuse left, but a wrong throw costs a fuse and your streak, which is worth far more.
Decide before you tap: flipping a switch and back again loses the clean bonus, even when the panel lights.

About Circuit Breaker
Circuit Breaker is a free circuit puzzle game you play in your browser: a fuse box, a little wiring diagram and a burning fuse. Power drops in from the mains at the top and runs down through wires, splitters, switches and dead ends to a row of terminals: one green bulb, a few red hazards and harmless ground terminals. Each switch sends the current one way, left or right, and every panel is dealt set wrong. Your job is to read the circuit, work out which switches to flip so the electricity reaches the bulb and touches none of the hazards, and lock it in before the fuse burns down. It is an electricity puzzle made of quick logic: a small flow chart you solve in a few seconds.
The board stays dead while you set the switches, so this is deduction rather than trial and error: trace the live wires from the top, see where the current would go now and find the fix. Nothing tells you how many switches to flip; there is always exactly one smallest fix, and finding it is the puzzle. Tap the big breaker lever (or press Enter) and the current runs through the board in half a second. Bulb lit and no hazard touched: the panel scores and the next one prints in at once. A powered hazard or a dark bulb is a short and costs one of your three fuses, and if the fuse burns out the breaker throws itself with whatever you set. When a panel shorts, rings show the switches that would have fixed it.
The panels never stop, and for the first sixteen they keep getting bigger: the first five need a single flip on a small board with three and a half to four seconds on the fuse, then two flips, then three, then four, on a six-by-six board with seven switches, splitters that send power both ways at once and four hazards, with up to eight seconds to solve it. Endless has no clock: you play until your three fuses are gone. Timed gives you two minutes on the same panels, for a quick round and for Swipe mode. Every lit panel scores 100 points, rising to 300 for a four-flip panel, plus up to 100 more for the fuse you have left, and 50 for a clean fix with exactly the fewest flips. A streak multiplier climbs a quarter per panel to ×3 for nine in a row, and a short resets it. Every seed deals panels of the same size and difficulty in the same order, each mode has its own leaderboards, and every run counts: top scores are replayed on our servers before they show on the leaderboards, which makes Circuit Breaker one of our competitive games.
On a phone, tap a switch to flip it and tap the lever under the board to lock it in: the whole game fits one thumb. On a computer, click the switches and the lever, or play from the keyboard: every switch carries a number, the keys 1 to 7 flip them, Enter or Space locks the panel in and P pauses. It plays the same on mobile and PC, with nothing to download and no account needed.
If you like logic puzzles that come down to one clean deduction, Circuit Breaker sits with our other puzzle games and the short challenges on the brain games page, and its two-minute version makes it one of our quick games too. Start slowly: read the first panels from the mains down, and after a few runs you will spot the switch that matters before the fuse has burnt a second.

Circuit Breaker FAQ
How long does a game of Circuit Breaker last?
Endless has no clock: it lasts until your three fuses are gone, a few minutes for most players and far longer for the best. Timed lasts two minutes, or less if all three fuses blow first.
Does it get harder?
Yes, panel after panel. The first five need one flip with three and a half to four seconds on the fuse, then come two-flip, three-flip and finally four-flip panels on a bigger board with more switches, splitters and hazards, with up to eight seconds each. From the sixteenth panel on the difficulty holds steady, and fresh panels keep coming for as long as you last.
How is the score calculated?
A lit panel pays 100 points for a one-flip panel, 160 for two, 230 for three and 300 for four, up to 100 more for the fuse left when you lock it in, and 50 for a clean fix with exactly the fewest flips. The streak multiplier adds a quarter per lit panel in a row, up to ×3, and a short resets it.
What happens when the fuse burns down?
The breaker throws itself with the switches as you left them. If they are right, the panel still lights, without the fuse bonus. If not, the fuse blows and you lose one of your three fuses.
Does every panel have a solution?
Yes. Every panel is checked by a computer against every possible switch setting: it is never already solved, and exactly one smallest set of flips fixes it.
Can I play Circuit Breaker on my phone?
Yes. Tap a switch to flip it and tap the lever to lock it in; it is made for one thumb. On a computer you can click, or use the number keys and Enter.
