The Weatherford Democrat has an article up about how board games are used to keep the inmate population happy and calm. Discipline issues are dealt with by denying the offender board game privileges.

Chess, cards, dominoes, Risk, and Monopoly are allowed. Texas Hold’em isn’t.

Offenders aren’t eligible to participate in these tournaments if they’ve been any sort of disciplinary problem. Disciplinary problems range from being caught with contraband to disrespecting staff. You have to really follow the rules to be able to compete this way. These chess players here are already starting to make the right moves in life, and that’s why they can be here.
