After determining the basic points, multiply based on the status as dealer and no-dealer as well as the win by ron or tsumo.

*When a non-dealer wins by tsumo, the player is paid 1 × basic points by the other non-dealers, and 2 × basic points by the dealer.

*When the dealer goes out by ron, the discarding player pays the winner 6 × basic points.

Each value to be paid is rounded up to the nearest 100. Because of how this rounding works, a tsumo win may result in a few hundred more points than a ron of the same value. (For example, a 1 han 30 fu hand scores 240 basic points. Without rounding, a ron would score 960 points, and a tsumo would also score 240+240+460 = 960 points. As each individual player's payment is rounded, ron scores 1000, and tsumo scores 300+300+500 = 1100.)

In other words, when hand wins by ron, the ronned player pays 100% of the hand's value. When a hand wins by tsumo, each player splits the payment evenly (with the dealer paying double).
To explain this in different terms: when hand wins by ron, the ronned player pays 100% of the hand's value. When a hand wins by tsumo, each player splits the payment evenly (with the dealer paying double).
