BitWise is a puzzle game about electricity. Players place parts on a board, wire them by hand, and a circuit simulator runs the result. It starts with a battery and a lamp and climbs through relays, logic gates, adders, latches and counters to a small stored-program machine. The grader checks what a circuit actually does, so a strange build that does the job passes. 238 levels across seven chapters end with the telegraph, with a Koch-method Morse trainer, a Sandbox, a level editor and Steam Workshop sharing.
