Pick a number that matches the given attribute. Be careful - it's possible that there won't be any more matching buttons left at the end of the game. Low is 1 or 2, high is 3 or 4, odd is 1 or 3, even is 2 or 4, square is 1 or 4, and prime is 2 or 3. There's only four different choices, so this should be about as easy as 1234, right?
