Advanced options

📝 Rating is a reference value associated with a specific Mortal network and can't be compared across different networks.

1. --player-id <ID>
The ID of the player to review, which is a number within 0-3. It is the number after &tw= in Tenhou's log URL, namely, the player sitting at the East at E1 is 0, and his shimocha (right) will be 1, toimen (across) will be 2, kamicha (left) will be 3. This option has higher priority over the &tw= in --url if specified.
2. See Mortal vs Mortal for comparisons.
3. --temperature <TEMP>
For Mortal engine only. It only affects displayed values and does not change action orders or ratings. Check the FAQ for details.
4. --kyokus <LIST>
Kyokus to review. If LIST is empty, review all kyokus. Example: E1,E4,S3.1, which means to review East-1, East-4, and South-3-1.
