Jack and Jill each have marble collections. The number in Jack's collection in a square number.

Jack says to Jill, "If you give me all your marbles I'll still have a square number." Jill replies, "Or, if you gave me the number in my collection you would still be left left with an even square."

What is the fewest number of marbles Jack could have?

(In reply to re: Lost their marbles (full solution) by SilverKnight)

Why isn't 1 an even square? An even square is the square of an integer (you can figure out which ones work).
