The NY Times crosswords are excellent...easy to use, easy to navigate, easy to read. I am a big fan and hope they continue bringing out more volumes. The 'Easy' volumes are divided equally between Mon, Tues, Wed crosswords and the 'Challenging' are the Thurs, Fri, Sat crosswords. If you like NY Times crosswords (are there any others?!), you will be happy.
The Chess game and the Backgammon games are well done...if you are psychotic about these games you may be disappointed but I like them. The chess game can be set from fairly easy to extremely challanging.
The Scrabble game is enjoyable, though its dictionary is 'creative' at times.
The Solitaire game (group of 12) is visually good and plays quickly...what can you say, it's solitaire. Beats carrying a deck of cards.
The Sudoku game was probably the best surprise for me...I never had really played before and wasn't really interested, but have to admit it is one of my favorites and I'm now hooked.
Hope this helps
