To determine the point value of a hand, the following procedure is used:
To determine the point value of a hand, the following procedure is used:
# If the hand is a [[List of yaku|yakuman]], then look up the 13 han values according to dealer or non-dealer numbers
# If the hand is a [[List of yaku|yakuman]], then hand scores 8,000 basic points × number of yakuman.
# Determine the hand's valid [[yaku]]
# Otherwise, determine the hand's valid [[yaku]].
# Count the han based on the yaku
# Count the han based on the yaku.
# Count any number of dora to the han count
# Count any number of dora to the han count.
# If the han count is more than 5, counting fu is no longer necessary
# If the han count is 5 or more, then counting fu is no longer necessary. Score the hand according to its han value on the scoring table.
# If the han count is 4 or less, then count fu
# If the han count is 4 or less, then count fu.
# After determining the number of han and/or fu, refer to the scoring table
# After determining the number of han and/or fu, refer to the scoring table.

For any who prefer to use the equation, basic points for 5 han or less are computed as


: '''Basic points = fu × 2<sup>(2 + han)</sup>'''
: '''Basic points = fu × 2<sup>(2 + han)</sup>''', using '''basic points = 2,000''' if the former exceeds 2,000
