===Tsumo vs ron === | ===Tsumo vs ron === | ||
The total points gained from a tsumo is | The total points gained from a tsumo is (nearly) identical to the points from ron. When a non-dealer wins by tsumo, the dealer pays ~50% of the points, and the other players pay ~25% of the points. When a dealer wins by tsumo, the other players split points equally. | ||
Any differences between tsumo and ron come from rounding. For example, a 1 han 30 fu ron is worth 1000 points. Without rounding, this would be split into 500 dealer / 250 non-dealer. Points in riichi mahjong are always rounded to the hundreds place, so for non-dealers 250 is rounded up to 300. Therefore, a 1 han 30 fu tsumo earns 500/300 (500 + 300 + 300), or 1100 points. | |||

When a hand gains +1 han, it is equivalent to doubling the hand's fu. (This does not apply | When a hand gains +1 han, it is exactly equivalent to doubling the hand's fu. (This does not apply once a hand reaches mangan.) | ||

Therefore, you | Therefore, if you multiply fu by 2, then subtract 1 han, you'll end up with the same score value. Likewise, you can add 1 han, then divide fu by 2, and end up with the same score. This means by memorizing the 30 fu values, you will also memorize the 60 fu values. By memorizing the 25 fu values, you will also memorize the 50 fu values. | ||
By proxy, this means that when a hand gains +1 han (without changing fu), it roughly doubles in point value. Due to rounding, a hand may not ''exactly'' double in value, but will be close to double. | By proxy, this means that when a hand gains +1 han (without changing fu), it roughly doubles in point value.

==Memorizing common values== | ==Memorizing common values== | ||
It is important to know the most common values first. Memorize the values for (1-4 han) + (20, 25, 30, 40) fu hands, as well as mangan+ hands, first, since they are far more common than anything else. | |||
