Orang Rimba or Anak Dalam tribe is a native resident of Bukit Dua Belas National Park in Jambi. They live harmoniously with nature that provides them resources to live and survive. However, the peace is suddenly broken. Some parts of the forests are massively exploited by irresponsible people, leaving nature prone to destruction and lost of many resources.

In Orang Rimba: The Forest Keeper, players represent two members of the Orang Rimba tribe. Each turn, they spend action points to move around the forest gathering resources, complete a goal, deliver goods to barter for other goods, and chase away the illegal loggers who irresponsibly exploit the forest resources for their own benefit.

The game ends after twelve rounds or when one of the players has managed to complete all of their goals.
