World 15 — Cairn A new kind of objective. Some cells now have colored markers; you win when each marker holds a tile of its required color. The board doesn't need to be empty — sometimes clearing is wrong, because it consumes the tile that was supposed to land on a target. Ten new levels in the first non-clear objective world Tessera has shipped. Animated tutorials New worlds now show the mechanic in motion. Locked tiles, mixers, gravity arrows, and target cells each have a short looping demo above the explainer text — readable in four seconds. Tutorial recall A small "?" button on the playing screen and the picker re-opens the relevant tutorial anytime. If the rules didn't stick the first time, they're one tap away. Wildlife Some levels now have small visitors. Sit still long enough and a fieldmouse, fennec, or frog might peek up from an empty cell to look around. They retreat the moment you make a move. Different species per world. Quality fixes — Levels you've cleared now show a check mark, even on out-of-order plays. — Sound resumes correctly when returning to the app from multitasking.
