Register

You can register to play a restricted Roshambot which will keep a permanent record of your moves and results as well as rankings of all the registered competitors. If you are not already registered, send email to roshambo@cs.stanford.edu. Note: I am not taking any new registrations for the restricted bot or arbiter.

You can request a userid and password but you are not guaranteed your first choice. You will receive email if you have been approved and will be given a userid and password. Please keep requested userids to 8 characters or less. Do not forget your userid or password or you will be crushed by a giant rock.

If you are already a registered user, you may go directly to the restricted roshambot at http://chappie.stanford.edu/cgi-restricted/roshambot.

Even if you are not yet registered, you can take a look at the current rankings of registered players.

Settle your disputes on the web via the amazing WWW Dispute Arbiter. This program is only available to registered users. You can open arbitration with any registered user, view your open arbitrations, or settle arbitrations opened with you by other parties. The WWW Dispute Arbiter is completely impartial.

If you are a registered user, you can try it out at http://chappie.stanford.edu/cgi-restricted/arbiter.
