What is Pure Logic?

Pure Logic is a single-player puzzle game with more than 200 levels built from interconnected logic gates. You use known input and output signals to deduce the remaining states so every gate's rules are satisfied. A training area introduces the symbols, and unlimited undo lets you revise your work while solving.
