One rule
Tap a tile, it turns a quarter step. That is the entire control scheme — there is no tutorial to sit through.
Rotate wires, light the board.
Every level is a tangled circuit with a single power core. Tap a tile to turn it a quarter step, and keep going until the last wire connects — then the current races out and lights the whole board.

Boards grow from a gentle 3×3 to a demanding 8×8. Every level is generated from its own number, so level 37 is the same level on every device, forever.
Wraparound from level 51
Wires start connecting across opposite edges: leave through the right, come back on the left. A second way to think, not just a bigger grid.
Fully offline
The game never connects to the network. No accounts, no sign-in, no cloud saves — your level number lives on your device.
Share a finished board
One tap turns the completed circuit into a card you can send anywhere. The image is drawn on your device and never uploaded.
VoiceOver support
Every tile announces its position and whether it is powered. A double tap rotates it.
Watch the power spread
Connected wires light up the moment you turn them, so you can always see how far the current has reached — and exactly which branch is still dark.
Tangled
Every tile starts rotated at random. Only the power core glows.
Connecting
Turn a wire into place and the current flows into it immediately.
Complete
When the last wire lands, the whole board lights up at once.
