Simona Says is a camera-based fitness game. The player listens to audio commands and performs body actions in front of the selfie camera. Movement is verified on-device snapshots with SAM 3.1 silhouette analysis. No pose model or skeleton joints are used. A pre-game pose library records personal reference templates and SAM zone markers per command. Live attempts are scored against the stored templates with body-relative signatures, grid profiles, and adaptive thresholds. Includes 5 modes: Easy, Hard, Bootcamp, Kids, VS/Online. Features guided calibration, sudden-death and forgiving kids rules, calorie tracking, stars, progress graphs, and a stats-only Muse Spark coach. All processing is fail-safe with UNVERIFIED pause instead of false losses.
