This game has a yellow background and the letters are rather small. For me, I do not feel this game is easy to play.  Give it a try it is a fun one.

Sudoku is a simple, addictive game of logic. Solve the mystery of the number grid with reasoning and patience . There is only one rule: Fill in the grid so that every row, column and 3×3 box contains all digits 1-9 only once. Have fun!
