Description by Karl Voskuil Written by the developer, not by AppBrain. Click to read.
Flippy the Train rides the rails, flipping switches to model basic digital circuitry: NOT, AND, and OR logic gates.
After building these basics, reuse them in larger tracks to create the more-complex XOR gate and half-adder. What is the fewest number of track segments required to build a half-adder?
Includes a sandbox mode for creating arbitrary track for Flippy to ride.
