Flippy the Train vs NAND
Price, ratings, monetisation and update history for both games, side by side — with what reviewers say about each.
Flippy the Train
Solve digital circuitry puzzles by building train tracks that model logic gates like NOT, AND, and OR. Challenge yourself to create complex circuits such as XOR gates and half-adders with minimal track segments. Explore a sandbox mode for freeform track creation.

Build a train track to solve digital circuitry puzzles! 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.
NAND

NAND is a simple puzzle game with six levels and no timer. Using bitwise operators and arrow keys, try to reach the goal at the top in the fewest moves! It will be difficult for beginners and people unfamiliar with bitwise operators, but you can improve with practice and understanding!
