Válka o Cintru, also known as VOC, was a Czech outdoor fantasy battle game created for Scout and other children’s groups. Inspired mainly by Andrzej Sapkowski’s Witcher saga, the event brought participants together for a large-scale field game in nature, using wooden weapons and a story drawn from the fantasy world. It was intended primarily for players aged 13 to 16, with participation possible from age 11.

The game was organized by Junák – Hiawatha Scout Center in Prague, together with other volunteers and friends. Its twentieth and final edition took place in 2018 at the Orlovy Scout base, after which the original organizers decided to end the event. The site preserves information about the game, including rules, photographs, videos, instructions, discussion, and contact details.

Although Válka o Cintru is no longer held, volunteers from Prague’s Oheň Scout Center continued its tradition by developing Mosty přes Jarugu, a new children’s event inspired in part by VOC
