Amend 370 to add to the first paragraph:
A record will be kept of the net number of points deposited in the piggy bank by each player. If the score of a player who has deposited points in the piggy bank would ever drop below zero, that player shall automatically withdraw enough points from the piggy bank to (a) ensure that their score ends up zero or (b) reduce their net deposit to zero, whichever is less. Under no other circumstances may points be withdrawn.
It is a curious fact, but nobody ever is sea-sick - on land. At sea, you come across plenty of people very bad indeed, whole boat-loads of them; but I never met a man yet, on land, who had ever known at all what it was to be sea-sick. Where the thousands upon thousands of bad sailors that swarm in every ship hide themselves when they are on land is a mystery. - Jerome K. Jerome, Three Men in a Boat
