Seashells Sudoku
A 4x4 shell grid sets the pace in Seashells Sudoku. Small children and first-time sudoku players get a compact puzzle with colorful seashells, one play mode, and a fresh layout for every new round. Sixteen squares fill the whole board, and the score drops as the timer climbs.
How to play?
Drag seashells from the left panel onto the board. Fill every empty cell. Match placement to the rule for rows and columns. The same shell also can't appear twice inside any 2x2 section. Move fast to hold onto more points and post a higher personal record.
