Everyone must of heard of SuDoku, the number game where you have to fill a 9 x 9 grid with numbers, without ever having the same number in a vertical or horizontal line or within the same 3 x 3 square.
I’ve played quite a few online versions of SuDoku, but JigSawDoku is the best one I’ve found so far! I think I like it because I’m lazy and don’t like typing and JigSawDoku using drag and dropable tiles with the numbers on. There are hints which can inform you if you have tiles in the wrong place, but I try not to use that 😛
