This game can guess your age using math. Just read the directions. Also, if you're 1, 2, 3, 4, 5, 6, 7, 8, or 9 then for your first number use 0 and your second number is 7. It's not very complicated.
BTW, if you're confused about the instructions above, let me break it down for u, dum-dum style. "4 da 1st direkshun (is dat speled rit?) put a 0. Then put a 7 4 da 2nd direkshun." (P.S I only used improper spelling above 4 effect. (I'm actually a grammar police irl XD) )
