Shamelessly ripped from Digg :
See if you can beat my high score of 684. To be fair to yourself try it just once and see how fast you can think.

How fast can you think?

1038

838

814. Without any coffee or cigarettes yet.

955, though I'd like to think I'd have been faster if I wasn't answering tech support calls

I noticed that the patterns change to different sets when you go to the page.

.

881 on the first try. Would be better if I didn't get two 0's from spending 3 minutes on a puzzle.

1051 on a second try because I got some of the same ones again ("play again" isn't working, only the refresh button is).

967 on a third try with as many new puzzles as possible (one repeat) with a best time of 17 sec.

1069 on a fourth try witn only one repeat (I think) and a best time of 14 seconds.

If only I wasn't so slow on the mouse.

953, on my only try, with 0 on one of the puzzles.

1030 at 2.15am after a long tiring drive.

1064 first try.

I should note that I do semiconductor layout... drawing polygons for a living.

1087 first try, good fun that game
1147 second time, one repeat i think
