Gate Singular

• One gate, unlimited possibilities

NAND is the only logic element in the game. NOT, AND, OR, XOR, latches, decoders, RAM, CPU: you build all of it from scratch.

• Built for enormous circuits

Worlds with millions of gates stay playable. Enough to make a 16-bit computer and run your own 24-kilobyte full-scale operating system on it at 1000 ticks per second.

• Tutorial challenges

As an alternative to the sandbox, you can work through challenges on how NAND can be used to make latches, flip-flops, adders, counters, RAM and program memory, step by step, all the way up to a working processor.

• Scale logic in seconds

Any fragment can be copied and pasted. Wires autoconnect, so scaling one component to thousands takes seconds.

• Library of blocks

Commonly used fragments can be turned into blocks that can be easily accessed, modified in a single place, or nested.

• A simulation that behaves like real hardware

There is no artificial per-gate delay: within a single tick, any change propagates through the whole device, just as a real circuit settles between clock edges. Nothing is time-synchronized for you: when you need it, you build the clock and the flip-flops yourself.

• Program your machine

Write a whole ROM in a binary or hex editor and flash it into your circuit in one go.

• Co-op

Invite Steam friends or host on a local network and build together. Each player runs their own simulation, so you can test your part of the machine while a friend is still wiring and debugging theirs.
