About Turn on Bulb

Turn on Bulb asks you to repair a small electrical route by rotating wire tiles. The aim is to create one continuous connection between the plug and the bulb, turning a scattered board into a working circuit. Each correctly connected path completes the current puzzle.

The gameplay is based on careful tile reading rather than quick movement. A single rotation can change how several wire sections meet, so the satisfying part is finding the arrangement that lets electricity travel all the way to the bulb. A hint can highlight the next incorrect tile when you need guidance.

How to Play Turn on Bulb

Tap or click a wire tile to rotate it 90 degrees clockwise.

Connect the tiles so the route runs from the plug to the bulb.

Use the Hint button or H key to highlight a wrong tile when available.

Press Reset or R to restart the current puzzle, and use Esc to return toward the menu.

Tips & Tricks

1Trace the route from the plug and check each connection before rotating another tile.
2Use the highlighted tile as a starting point, then inspect the wires beside it.
3If the arrangement becomes confusing, reset the board and rebuild the circuit from one end.
