Presidential $1 Coin Program - Play Coin-Doku
My wife and I both enjoy sudoku and I found this on at the us mint. It uses coins instead of numbers which I find much harder. I will often count from 1 to 9 in a box, on a line or on a column to quickly identify which numbers are missing. Using some other token make me think about the tokens themselves and not just the placement.Presidential $1 Coin Program - Play Coin-Doku

I found this site really helpful when I was learning how to play sudoku. I'm not sure if you're interested in watching how to videos, but these are great for beginners.
