GateZ — Wire the logic gates that open each door.

How to play GateZ

1. 1Each door has a truth table or a Boolean expression.
2. 2Tap a gate to place it, then tap an output and an input to wire them (dragging works too).
3. 3Test your circuit — every row of the truth table must match.
4. 4Use as few gates as the par for three stars.
