Conjure is for kids who draw but don't code. They photograph a drawing and play it as a real game minutes later, with their own cutout characters as the physics bodies. Every build and every live edit is proven playable by code before the kid sees it, so the agent's word is never the verdict. Muse Spark finds each figure in the photo and SAM 3.1 cuts it out. Muse Wonder pitches three games in different genres, and the kid picks one. Three agents on Muse Wonder then race to build it in parallel Vercel Sandboxes on dotframe, our open-source engine. A playtester written in code runs the game headless: fourteen simple policies must fail to win, and a save/restore search must find a win. A visual QA pass on Muse Spark grades rendered frames and sends blockers to a fixer. Only a build that passes both ships. While playing, the kid asks for changes like "add a rainbow". Muse Image draws it in the style of the original drawing and Muse Spark edits the code. The server checks the game still runs before the edit lands, and undoes it if it breaks. The match keeps going. Measured on this week's builds, one run each: photo to three concepts in 70 to 105 s, pick to playable in 150 to 639 s, US$0.62 to US$1.67 per game, all seven verdict ok. Eight games are published and playable at https://conjure.crafter.run Prior work: the dotframe engine existed before the hackathon (tag pre-hackathon, 2037a05). Everything else was built Oct 27 to Nov 4. The family scenes in the video are generated b-roll; every product shot is a real screen recording.
