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
A logic gate puzzle game where players use bitwise operators to navigate through levels. The goal is to reach the top with the fewest moves, offering a challenging experience for those new to bitwise operations.
- Logic gate puzzles
- Bitwise operators
- No timer
- Minimal moves challenge
- Six levels

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 5.0 for Flippy the Train against 5.0 for NAND. That said, the two scores are not equally well evidenced: Flippy the Train has 5 ratings behind it against 1, so its average is the more settled of the two.
