In tagging, the mouse who got tagged the fewest times (and is not the tagger by the end of the round) wins!
When you are the tagger, try to catch other mice to make them the tagger. To tag, just stay close to a mouse for a second or two. Every time you are the tagger you get ability to spawn 1 box.
As a RunawayEdit
Avoid the taggers if you are not (they have blue name).
