Fractory is a grid-based automation puzzle game where you're routing *numbers*. Place operator nodes (+, −, ×, ÷) and splitters on a grid, then drag coloured links to connect fixed sources to fixed sinks. Values flow instantly and continuously through your network. No timers, no waiting. A puzzle is solved the moment every sink is receiving exactly the value it needs. It's a logic game first, but the arithmetic is real. A natural way to practice mental math without it feeling like homework.
