MADISON, Wis. (AP) — A man serving life in prison for first-degree intentional homicide lost his legal battle Monday to play Dungeons & Dragons behind bars.

Kevin T. Singer filed a federal lawsuit against officials at Wisconsin’s Waupun prison, arguing that a policy banning all Dungeons & Dragons material violated his free speech and due process rights.

Prison officials instigated the Dungeons & Dragons ban among concerns that playing the game promoted gang-related activity and was a threat to security. Singer challenged the ban but the 7th U.S. Circuit Court of Appeals on Monday upheld it as a reasonable policy.
