From UB FAQ:
How do I get a hand history?
Every hand dealt is given a unique number. When you are at a table you will see in the upper left corner the table name, stake level, game type and hand number. (Example: Boston $3/$6 Hold'em - playing hand #3121027-13719).
When you are at a table, you can see the previous hand history by clicking on 'get hand history' that is found in the lower right hand corner of the screen.
If you want information on multiple hands, or for a game that you previously played, you can contact
memberservices@ultimatebet.com and request the history be emailed to you. It is very helpful if you have the exact hand number(s). If you do not have these, try to provide as much information as possible including your player name, the name of the table, the approximate time/date you were playing and the names of other players at the table.
