POLAR SUDOKU
The objective is to fill a 4×4 grid with imags of Arctic animals: ARCTIC TERN, NARWHAL, PUFFIN and MUSKOX in such a way that each column, each row, and each of the 2×2 grids that make up the larger 4×4 grid contains all of the images, and every image appears only once.
This game can be played by younger kids, or older kids with short (w.g. 1 minute) time limit.
