Ludoteka is a website planned to play against some other players, and offers several features related to each specific player,
such as game history, lists of favorite players and games, and messaging system.
Therefore, you should have an user account.
Anyway, before creating an account, you can test the games playing against robots, or unrated solitaire games.
Signing up is very easy and fast.
You just have to tell us the nickname you want to play with in Ludoteka, a password and a valid email.
You can leave the email for later, but some functions will be disabled while it is not validated.
If you have a Gmail or Facebook account, you can also sign up by directly linking it to Ludoteka.
