Cool game; used to do something like that with kids, but more in context of sequence patterns. still, the game is limited to functions that are specified intensionally. Extensionally specified functions with no readily identifiable intension (like a function whose pairs are the result of a random pairing) are not really guessable. Oh well those are boring anyway...
