The LAN has no “You must play this game at that time” rule. Your free to play whatever you want at any time during the event. There is a list of games and times shown up on the site and on the projector at the night for organized games. These games are listed in advance and spaced out so only one is played at a time. This allows people to choose when they want to do there own thing or join in for a change to win a prize.
