Seashells Sudoku Game

Seashells Sudoku is a simplified version of Sudoku for children with a 4 by 4 playing field. You need to fill the whole playing field with seashells. Do not repeat seashells in the same column or row. Each time you start the game, you will find a new puzzle. The game has only one difficulty mode and that's cool, because it can be played by small children and just beginners to sudoku players. To learn how to play, you just need to drag and drop the colorful shells into their places and fill in the empty cells. The game board contains only 16 squares, so it won't be hard to assemble this puzzle.
