Connect the red START to the green GOAL with jumper wires. Find the misplaced or missing jumper, then hit Power On. Play full screen →
How to play
The goal
Get current from the red START flag to the green GOAL using only jumper wires. Each board has a bug: a jumper in the wrong hole or one that’s missing. Fix it, then hit ⚡ Power On to test the path.
Controls
- Move a misplaced jumper, or drag a new one from the jumper tray. Jumpers are pre-cut to lengths 1, 2, 3, 4, 5 and 7, so pick the right one.
- ↺ Reset puts the board back; ⚡ Power On tests it.
- The speaker button turns sound on or off.
How a breadboard connects
- The 5 holes in a row (a–e, or f–j) are connected to each other.
- The center gap splits e from f, so a jumper has to cross it.
- The power rails run the long way, and split rails need a bridge.
Lives, levels and the boss
You have 3 lives, refilled after each boss. Levels 1–3 need one fix, levels 4–6 need two or three, and in levels 7–10 you build most of the path yourself from the tray. Each level has 5 boards and then the Short-Circuit Gremlin boss.
No saves to worry about: each game starts fresh, and only your sound on/off choice is remembered in your browser.
