Combine converters, connect the pipes, and deliver nuts to the hamster.

This is a logic puzzle where you place converters on nodes to design the flow of the pipes. Sort the nuts and stones flowing from the source using combinations of converters, and deliver only the nuts to the hamster waiting at the goal. Delivering a stone counts as a miss — two misses and it's game over.
