Electro.io

A line-connection puzzle about joining opposite electrical charges without overlapping paths.

Pair positive and negative electrons while reserving separate routes for every connection.

Electro.io places electrons on a puzzle field and asks for all of them to be connected. A valid pair must use opposite charges, so matching two identical charge types is not allowed.

About Electro.io

The drawn lines introduce a second restriction: connection paths cannot overlap. Mouse input creates the routes, combining charge selection with spatial separation across the board.

Objective: Connect all electrons in opposite-charge pairs without overlapping lines.

Core loop

  • Choose opposite charges, draw a connection, and preserve clear space for the remaining routes.

How to play Electro.io

  1. Use the mouse to select an electron.
  2. Connect it to an electron with the opposite charge.
  3. Continue until all charges are joined without overlapping any lines.
