Where are the instructions?
Not only that, but in the math (being timed), there is text COVERING UP the equation, forcing one to use EXTRA time to discern the equation to be able to compute the answer. I find it hard to believe that the person(s) who designed these games, imagined that anyone playing them would want to hear A LOUD TIMER TICKING IN THEIR EARS . . . Someone needs to actually check these games for errors, and check them out for functionality prior to marketing them. If these things were to be addressed, I think a 5-star rating could be deserved, because the games/tests are great.
