I had one of those plastic number-slide games when I was a kid. I
loved it! So I was
thrilled when
Number Slide became available for the Kindle—and it's free! I play it every night before going to sleep. I usually play the medium puzzle. My best time so far is 1:00, which I don't think is too bad since I'm usually on the verge of falling asleep.
I also enjoy
EA Sudoku ($3.99),
Triple Town ($3.99), and
Dots and Boxes (free). I have some other games on my Kindle, but those are my favorites so far.
