Games Like NAND²

Build a computer from a single NAND gate, alone or with up to three friends on the same board: from clicking relays to a 16-bit CPU with a pipeline, branch prediction and a cache. Then write the programs it runs.

Invite friends through Steam or connect over a local network: up to four players work on one board at once. You see everyone's cursor with their name, parts and wires appear the moment they are placed, and a passed check counts for the whole team.

You start with one NAND gate. Wire it into NOT, AND and OR, then adders, latches, registers and memory.

Every part you finish goes into your palette and becomes a building block for the next level.

Circuits are simulated gate by gate, fast enough to run a whole processor live.

In era V you add a keyboard and a pixel screen, then run a first-person shooter on the CPU you wired yourself.

The section editor builds your own level chains with reference solutions, tests, briefs and hints. Share them on the Steam Workshop.
