Amazon Digital Services had one game for the Kindle when I received my WiFi-only Kindle in early September. However, if you check out Kindle Store for games published by Amazon Digital Services, you now find two more games (for a total of three).

The game “Shuffled Row” was available in early September. “Every Word” and “Mine Sweeper” appeared since then.
Shuffled Row and Every Word are word puzzle games. Shuffled Word has a kind of Scrabble-like quality and point system. Every Word is a scrambled word game. Mine Sweeper is a variant of the classic find the hidden mines game.

If you think games on a gray-scale screen with a relatively slow refresh rate are not worth trying, think again. I’ve found the games to be quite engaging, addictive, and a lot of fun. And, all three games are free. So, it doesn’t cost you anything to try them.
