   Yeah, image maps do sound more in line with what Bruce described in his response to this.

It also assumes that it's not a problem if the user cheats. There's a
bit more control in that area when one is using a Java applet and (I
assume, but haven't looked into it) Flash. (Although, it's obviously
still a problem, just less of one.)

But, if one's going to go with a solution like yours, one could
instead use image maps of an image with the dots already placed. The x
and y coordinate of the click would then be accessible, and would be a
bit more precise. It would also avoid the need for a table. The images
could be pre-made or easily created with PHP and the GD library or
similar packages.
