A puzzle game about repairing a strange, corrupted computer from the 1980s. Each puzzle asks you to make a small grid of processor nodes turn input numbers into the expected output.

How you code

You write assembly code for each node, in a tiny language of about a dozen instructions. Each node holds only a few lines and has almost no memory, so the real work is splitting a task across nodes that pass values to each other. Once a puzzle is solved, histograms compare your cycle count, node count and instruction count with other players'.
