How the daily problem is chosen
The table changes from day to day in a fixed cycle of eight: the mill table appears three times, the other five tables once each.
Difficulty follows the weekday: easy on Monday and Tuesday, medium on Wednesday and Thursday, hard from Friday to Sunday.
The date is read from your own clock, so a new problem appears at your local midnight.
The order of tables in the eight-day cycle: Nine men's morris, Draughts, Nine men's morris, Reversi, Four in a row, Nine men's morris, Five in a row, Dots and boxes.
