Hand size
Set this to a lower value to simulate a fragment of a complete hand. This assumes that part of the hand is already completed with other tiles from a different suit.
Odds of generated hand being guaranteed Tenpai
Adjusts whether hands are generated at random or using the Tenpai algorithm. Random hands can still be Tenpai by chance.
Odds of honor tiles being included in the pool
This does not guarantee honor tiles will be used in the hand, only that they are included in the available pool of tiles when randomly generating a hand
Maximum calls allowed in hand generation
Allows groups to be generated open with random calls, up to the maximum set.
Odds of groups being called (ignored when above is set to OFF)
This is rolled for each of the maximum allowed calls set above.
Odds of Pon calls being Kan calls instead (ignored when calls are set to OFF)
This is rolled for each previously rolled Pon call and will only apply if sufficient tiles remain.
Odds of tiles being displayed upside-down.
This is randomized as an extra challenge. This is rolled for each tile separately.
Odds of hand being unsorted.
This is randomized for as an extra challenge. This is rolled for the whole hand (closed portion if calls are made).
Hand suit
Only one suit of tiles is used to generate hands that are always either Flush or Half-Flush. The choice is purely aesthetic.
