Registration allows your scores and results to be saved and compared with other visitors. If you are not interested in tracking your results history, there is no need to register. You are still welcome to play anonymously. Visitors have full access to every puzzle on the site whether they have an account or not.
Including an email address is optional. If you choose to submit your email address, it will never be used for marketing purposes or distributed to others. The only time you would ever receive an email from us is if you've forgotten your password and you want it to be reset.
Usernames can include spaces and any other characters you want. Offensive usernames will result in a permanent ban at my own discretion.
This site doesn't store sensitive information, so I only require that passwords be a minimum of four characters long. It's strongly suggested but ultimately left to the user to create a strong password. For its part, this site places no restrictions on character content or maximum password length. Type entire essays in German or Yiddish or Arabic, they're all valid passwords. But for your own sake, don't use the same password here that you use on your email account – or anywhere else, for that matter.
