The Ancient Ruins is an obby found in the ''Obbies'' shed at the Playground. Previously, after completing the obby, you would receive 21 as an adult or 15 as a baby. Now, players receive a badge after completing the obby. The obby is made up of wood pieces hanging over a pool of lava. The goal is to finish without having to re-spawn at the beginning and complete it without having to restart.
You can no longer receive rewards for completing obbies, since the family system was used for a hack and this was believed to be one of the reasons by many people.
