Pour shells between tubes until each holds one kind. No timer, no losing.
A calm sorting puzzle from Coral Cove. Glass tubes stand in the reef, each holding a jumble of seashells. Tap a tube to lift the shells off the top, tap another to pour them in — they only settle onto their own kind, or into an empty tube. Keep pouring until every tube holds one kind, and it seals with a gold rim. There is no way to lose. No timer, no move limit, no stars, no failure screen. Undo is unlimited and free, forever, and you can restart any level at any moment. Sixty levels across six biomes, and each one adds exactly one new idea. The Tide Pool teaches the pour. The Kelp Forest gives tubes different heights. The Coral Reef adds a tube sealed under crust that cracks open the moment you finish your first. The Deep Blue drops in sand, which sinks to the bottom and will sit under any colour. The Trench brings twin shells, split down the middle in two colours and counting as either. The Sunlit Cave ends with nacre — a blank shell that becomes whatever you pour it onto. Finish all ten levels of a biome and you earn a keepsake shell for your shelf. Six biomes, six shells, all earned by playing — never gambled for. After the sixty, Open Water keeps generating fresh levels forever. Every level has a shortest solution, and solving one in that many pours is a Perfect pour. It is never required and never shown in advance — just a quiet extra to chase.
