The level of play varies from week to week. Sometimes it is designated "advanced" or competitive and other weeks the level of play is more welcoming to beginners. Often, the level is determined based on the number of hard-core regulars available to play. However, the group always tries to provide a fair balance to ensure that newbies are welcome.
