Hey Miguel, I saw that you were interested in some help on the site. Any questions specifically? Mainly the site is to play risk, and board makers have gone and taken the options and made their own versions. There are some unique rules and features like elimination bonuses, artillery borders and manipulation of dice odds, as well as capital cities. If you'd like an explanation or would like to play a game and chat about such things feel free to invite me. Thanks, ENygma
