In general, a fast way to determine the uma scores requires the difference between two sets of numbers. First, one must find the raw score rounded to the nearest 1000 and divided by 1000 (A). Second, one must either find or know the end score difference. If necessary, that requires using the original process to determine uma (B). Now, regardless of the raw scores, the difference between the end scores and the rounded raw scores (divided by 1000) remains constant. | In general, a fast way to determine the uma scores requires the difference between two sets of numbers.

In the event of tied scores at the end of a game, then the tie-breaker based on the initial [[Jikaze|wind seating]] (or the first hand) may applied. The player closest to the dealer position takes the higher position. Afterwards, the final score procedure takes into effect. Even with tied scores, the player in the lower position will receive a lower uma score. Alternately, any oka and uma may be split evenly between the tied players, resulting in a shared placing. The specific ruleset in use determines how this is handled. | In the event of tied scores at the end of a game, then the tie-breaker based on the initial [[Jikaze|wind seating]] (or the first hand) may applied.

{{main|Multi hanchan format}} | |||
For some competitions, the same four players play out two hanchan or more to settle a score. This is due to one hanchan deemed as inadequate to settle a score between four players due to factors such as luck. Varioius tournaments and professional organizations utilize this format. | |||
