Completed! Nice idea and design, but I'd rather do a more difficult test than a looong one. The last 99 hits were pretty boring.. and not challenging. But overall nice simple game :)
Rofl! Even though it will always give out 50 -> ((2x+100)/2-x=50), the game guessed it wrong!! :O Also, in the "For example", the "d)" is wrong, it should say 62.
Umm.. I just stumbled upon a "crappy" one. Both literally and metaphorically. But overall it's nice :) Maybe you could put some relaxing music and read them aloud and play them all automatically :D Yup, "me is gamer; me is lazy."
