Thanks, Fillippe! That works well. I had tried _LIMIT 60 before, but it lagged horribly the way I was getting the mouse input so I removed it. The way you put them together works very well and I will adopt that method. Your game looks great!
Zeppelin: I think it is the same type game, originally called 5x5 according to the wikipedia. I first ran across it as called lights out, on a pc.
I have edited the code with Fillippes suggestions, and also added _DISPLAY/_AUTODISPLAY in the updateboard SUB to reduce any screen flickering.
