As a kid I played something similar to this, and monetary value (A=0; J=11; Q=12; K=13) was introduced as a rule. Someone played a card they wrote on a 10 that forced me to eat a worm to destroy the card (and get $10). I never got my $10 and felt guilty for months after, and guiltier when I realized I felt guilty for eating a worm without compensation. The fact I felt I would not feel guilty otherwise confused me.

Would play again.
