Seashells Sudoku (Seashells Sudoku)
Let the adults play Sudoku with numbers, and for the little ones we have specially prepared a simplified puzzle called Seashells Sudoku. Its rules are similar to Sudoku, but instead of boring numbers, there are colorful shells. Some of them are placed in cells on the field, and the rest you must add so that there is no free space. Remember that there should not be two identical shells in rows and columns. To make it easier to solve the problem, you simply cannot take the wrong step. However, you still have to think.
