+# Title:      	Pebbles
+# Description:  Pebbles a game based off of Nim. Nim is a mathematical game of strategy in which two players take turns removing (or "nimming") objects from distinct heaps or piles. On each turn, a player must remove at least one object, and may remove upto 3 of objects off of the pile. The goal of the game is to avoid taking the last object.

+
+The more games you play the smarter the croc will seem to get as it builds up knowledge.
