You are but a cog in in infinite machine. Yet you are all the cogs. There is no end and no beginning. Only computation.

There are only a handful of base components to master. Clone replicates a token. Filter redirects a zero of Nul token to another path. A lock will not allow a token through until it has been unlocked from the side. Switch directs tokens left or right, which can be selected by supplying a token at the other end. And finally a nullifier converts a zero to a Nul and vice-versa. All other units in the game are ones made by you.

User Interface

The design interface has plenty of quality of life features making construction as painless as possible. Copying and pasting between designs, moving and flipping components, comments, and custom colors to help you.

Testing

Testing allows you to view the operation of your design while inspecting the inner workings of subcomponents. Option skipping steps where no activity can be seen at the level you are viewing.

Community

Your designs can be exchanged with friends or shared with the public using strings. There are global leader-boards as well as being able to see your friend's scores.
