Number Machine: Math Factory: hex-grid factories, optimize for size and speed

Number Machine is an open-ended factory puzzle about designing autonomous machines on a hexagonal grid. You move, combine, split and modify numbered orbs with specialized gadgets — conveyors, pushers, lasers, magnets, rotators — until the structure and the values come out right. It wears its Opus Magnum and Infinifactory inspirations openly, but the twist is that you place machines and let the orbs travel through them rather than writing a program.

Optimize for size and speed, chase better scores, and sink time into bonus tasks and extra score categories once a puzzle is already solved. The colorful, clean cel-shaded style and seamless animations — one continuous camera move from start to finish — do a lot of the presentation work, and full controller support is a welcome extra in this genre. It runs on Windows, macOS and Linux.

A control quirk is worth knowing: pressing Escape during a test may open the pause menu instead of cancelling the run. It's still a young release with a modest following, so take this as a warm early recommendation rather than a sure thing.
