How to play

Flip the switches until the lamp lights; the glowing wires show what each gate does. On level 2 your child names the gate behind a truth table. Four right answers finish a level.

Levels

  1. Level 1One gate: light the lamp.
  2. Level 2Which gate makes this truth table?
  3. Level 3Two gates and three switches.

A tip for parents

Ask your teen how a light with two switches on the stairs could work: which gate is it?

Works on phones, tablets and computers, with nothing to install. No ads and no tracking.
