It's not as good as the practice pad, as you can't take back moves, and you can't quite do Brainking's rules exactly (the king can always re-enter the central square in my implementation).
The settings required for an approximation of our familiar tablut are:
Layout: Jarlshof I; King strength: weaponless; King's objective: Board edge; First move: King and Defenders; everything else is as set by default.
While it has shortcomings as a practice pad, it does allow you to experiment with other sizes of board and rules. There is also inadequate documentation.
(hide) If you want to save on bandwidth you can reduce the amount of information that shows up in your pages in the Settings. Try changing the number of games in the main page and the number of messages per page. (pauloaguia) (show all tips)
