Shell Slide

Shell Slide is a sliding-puzzle game set on a sunlit tidal flat. A tray of shells sits at the centre of the screen, one tide pool is empty, and a shell mosaic card is pinned above it. Slide shells into the pool until the tray matches the card.
Each tray has exactly one empty pool. Swipe or tap a shell that touches it and the shell slides in — the pool moves to where that shell used to be. The pool is marked with all the shell colours, so it reads as a spot that can take any shell.
Line up a whole row or column in one colour to trigger a Wave: the row lights up in teal, foam bursts across the tray, and you earn extra moves to keep going.
Features:
- One simple action: slide a shell next to the empty pool
- Trays from 4x4 up to 5x5 with 2 to 4 shell colours
- A mosaic card pinned above the tray shows exactly what to build
- Wave bonus: complete same-colour rows or columns for extra moves
- Move counter shows used and remaining moves at all times
- Star rating based on how efficiently you finish each mosaic
- 15 levels with growing tray size and tighter move limits
Retry drops you straight back into the same tray, so a rough start costs you nothing.
