You can play Roller here:-
The "kr/s" figure is showing thousands of rollouts (complete random games) per second.
Interestingly when pitted against a true random mover version of itself, Roller wins all of the games, other than sometimes accidentally falling into 3-fold repetition because it does not know that rule.
Roller can be used in Arena etc like Lozza.
Roller does not terminate at known draws like KK for example, because that is definitely feeding in knowledge; however tempting it is to do so in the name of kr/s.
You can change the number of seconds Roller takes to move from the entry field above the board, which by default is 10s.
While thinking Roller displays a status above the board of the form:-
time so far (seconds) |
thousands of rollouts (games) so far |
thousands of rollouts per second so far |
best move so far
After moving Roller displays information for each root move:-
move, average length of rollout (plys), total score and number of games, average score.
**** depicts the best score.
