I am interested in anyone's experience and recommendations regarding
Handheld Electronic Sudoku Games.
I bought one at Costco which would not even let you save a game...needless to say it was returned.
I am particularly interested to find one which has the ability to see possible allocations in unallocated cells.
Other desirable features? Backlit. Physical size. Good visibilty. Generates high quality games at different difficulty levels. Can save games in progress.
I am new and apologize if this topic already exists..I did not see it, if so.
