"We are all on a merc crew; you must have done something wrong in your past." Vince rolled his shoulders, "I shall start the bet with the murder of an unknown man, I killed him on a job, just an unlucky sod that was in the wrong place at the wrong time."
If I win the hand then there is a sin I do not have to account for at the end, should there be a higher power. You make a bet on the simple standard of crimes, murder, theft, assault, and so on. If you look closely each of the chips on the table has a crime type written on it. The winner has one sin of equivalent value removed from their soul and thus that bet and particular sin cannot be used again, you can however bet another similar sin, it just can't be the exact same sin. Not only is it a good way to pass the time and to heal ones soul, but you get to know people as well."
Vince looked at the other player to see how confused they looked, "I know this is an odd concept if you have not grown up on my world, but when one must steal and kill to survive the sins pile up."
