The '''uma''' {{kana|ウマ}} is a set bonus/penalty for ending the game at a certain placement. The typical point spread uses the format of {{uma|+A|+B|-B|-A}}, where 1st place receives A, 2nd receives B, 3rd loses B, and 4th loses A. | The '''uma''' {{kana|ウマ}} is a set bonus/penalty for ending the game at a certain placement.

For example, uma can be set to {{uma|+30|-5|-10|-15}} or {{uma|+15|-5|-5|-5}}. Uma usually adds up to 0, but technically does not have to. Modifications may be used to make the conditions easier or harder, namely in tournament settings. | ||

This means, for these oka/uma settings, 1st place final score is equal to <code>(raw score/1000) + 10</code>, 2nd place final score is equal to <code>(raw score/1000) - 20</code>, and so on. In other words: instead of having to calculate oka and uma every single time, when you are 1st with these settings, you can divide score by 1000, then add 10. | This means, for these oka/uma settings, 1st place final score is equal to <code>(rounded raw score/1000) + 10</code>, 2nd place final score is equal to <code>(rounded raw score/1000) - 20</code>, and so on.
