All players start with a score of 490 “Debts to Forgive” – they want to drive this score down to zero [“0”] to win.
During a player’s turn, they can select to ADD debt to another player or SUBTRACT debt from their own.
If all players had a phone application (iOS/Android) with a simple counter it would help the others playing know who is in the lead.
If a player reaches “0” [or less than zero] – present some sort of celebration clip [like fireworks with a “490” logo & say “CONGRATULATIONS! YOU WON 490 CARDS BY FORGIVING ALL DEBTS!”]
Allow players to post their win to Facebook
