You enjoy Sudoku, but you’re up to something new? Here is what you are looking for! Side by Side is a fascinating puzzle based on a few very simple rules. In a 6x6 (or larger) grid, you start off with a few given numbers. It is your job to fill in all of the grid’s boxes with any of the numbers 1 to 4 or an X. A number indicates how many of the directly adjacent boxes also contain a number (i.e., not an X). Further, two directly adjacent numbers must not be identical. Features: - more than 200
