Opus Magnum
Build and time alchemy machines, then optimize them against the world
You design machines that carry out alchemical processes to make remedies, gemstones, weapons and more. You place arms, tracks and glyphs on a board, then set each arm's moves on a timeline. Puzzles are open-ended, and you compete with friends and the world for the simplest, fastest and most compact solutions. You can export any solution as an animated GIF.
