Sudoku Christmas

This is a classic sudoku game. You can choose any one of three grids (4x4, 6x6 or 9x9) and can set the difficulty level. The goal is to fill a selected grid with Christmas items so that each column, each row and each sub-grid respectively form a grid containing all the items without repeating anyone.
