I never played Sodoku before coming to FusionCash. I am not a math person and figured I wouldn't like it, but it is so much fun!. There's been a handful of times when I got caught up in it and played for so long that I had to start the PTC all over again. The game is always what I go to if I have seconds left over after I've been to the first 4 sites, then I see how many numbers I can fill in before the timer runs out!
