Thanks, but that is the wrong game.
The numerix she has is a numbers-addition game. It start with a screenful of numbers from one to nine. You begin from #1 and keep tapping numbers in sequence until you get to double digits when you must add numbers together. It is timed and when time is expiring you start hearing a "beep" that drives you nuts. Give you an idea of the challenge, the hgihest I have reached is 32 and I think the record a few weeks go was 64!
Please someone find this thing for Nexus 7.
Or, how can I copy it from my wife's N7?
