Fingerjig is an interesting typing game (done in Flash) to help you calculate your touch typing speed as well as word accuracy.
The typing speed test will run at different levels for six minutes though you can take breaks and your score (word per minute, letter typed, etc) will be displayed after each level.
The word length gets larger as you cross levels.

Typing tip - try to improve your net words per minute by making fewer typing mistakes - experiment with typing a bit slower.
