His rules are

(1) The Number must be "useful"

(2) Not "arbitrary" (Herpderpbillion)

(3) You can't say the largest number any one could think of +1, that's not allowed and that's cheating

(4) No Infinity.

That's it.

I reject (1) and (2) as pointless and difficult to define in any meaningful way, but (3) and (4) are essentially on my list.
