Fair game. Some of the fish in the right tank seem to feel the urge to migrate to the one of the left. Their kamikaze way of achieving this force you to catch them in your bowl from which they immediately jump out again to get one step closer to the fish tank on the left. Obviously more fish will jump from the tank after you reach a higher score. When you drop a fish, a cat will jump out from the left and grab the fish and eat it. Game B is actually a bit more fun because the fish randomly chose a direction when they emerge from your bowl and sometimes the fish in the left tank left start the journey to the right one as well.
