One little spark at a time01 · Close the loop
A little connection.
A lovely discovery.
Electricity needs a complete path. Connect the battery to the bulb and back again, then watch your idea light up.
In Zaplet, drag parts onto the board and connect their silver snaps. Try a new route, undo a move, or ask Zap for a nudge.
There’s a gap. Close the switch to give electricity a complete path.

Good to know
A few little answers.
Can I play without watching a video?
Yes. The board’s bulb button gives free hints. Video hints are an optional extra, and unavailable ads never stop you progressing.
How do ads and Remove Ads work?
The free game has a bottom banner and occasional ads between completed levels. The one-time Remove Ads option removes those ads and gives extra hints without videos. Purchase availability and price appear in the app when its store product is available.
Where does my progress go?
Your stars, preferences and Free Build project stay on your device. There’s no player account or developer-operated cloud save. Restoring purchases restores eligible ownership, not puzzle progress.
Is this a real electronics kit?
Zaplet is a playful digital simulation. Use it to explore ideas, not as a guide for wiring physical electronics. Never experiment with wall sockets.
