What is Smart Settlement?
Smart Settlement looks at every bet result in the round and figures out the smallest set of payments needed to settle everyone up.
Example: if A owes B £5 and B owes C £5, Smart Settlement just asks A to pay C £5 - instead of two separate transfers. With four or more players this can collapse a dozen tiny payments into two or three.
You'll see one row per payment with the from/to/amount. Each person marks their own row as paid (cash, Swish, Stripe - whatever you used).
