the 2nd game, click the prime numbers, my second board had only a 1 as a potential candidate, and 1 is not considered prime. the other numbers were all composites and I was awarded a big fat zero for knowing all this. (I went back in and the game does not allow clicking the 1, good; but the description "divisible only by 1 and themselves" doesn't really rule it out. maybe don't give 1's or explain this)

clicking the prime numbers is a bit hard to do, and they scooch out of the viewing area and disappear for a bit. not complaining but while i was figuring out the game on my first board, I did terribly because of that.

given the level of math proficiency required for the prime number game, I was shocked in the next math grid game when using the ascend/descend buttons it simply told me every time I had hit the right answer. thought this was how to play so I didn't try typing numbers in. on my firefox browswer the answer numbers are too big to fit in the cells.
