Fractory

Fractory is a 100% FREE 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. No trial, no time limit, no ads, no subscription, gameplay is all 100% Free WHAT'S INSIDE • Daily Challenge : one puzzle a day, the same for every player, with a live leaderboard ranking closeness to the target • 63 hand-authored puzzles across 6 difficulty tiers, from a five-minute intro to genuine head-scratchers • Canvas Play : an unbounded sandbox where you unlock new numbers by delivering them, then chase down goal cards across milestones (Fibonacci, primes, squares, perfect numbers, times tables, Pascal's triangle...) • Numbers Mode : Countdown-style number puzzles: combine six numbers with the four operators to land as close as possible to a target • Puzzle Creator : design your own puzzle and share it to the Community Puzzles library, or play what other players have made • Community Puzzles : Play hand made puzzles from the community!
