Each player has a rating. Every point is a weighted draw between the two ratings, so a stronger player wins more points but upsets happen. Prices come straight from that model with a house margin of about 5% on winners and next point, 6% on totals and 12% on margins.

Markets suspend while the ball is close to a goal and between points. Cash out pays 94% of what an open bet is worth at the current score. Ratings move after every bout. All balances are play money with no cash value.
