The spirit of togetherness and cooperation seems to be declining among some of Indonesian communities. The Independence Day celebration can be used as a momentum to strenghten the spirit through various competitions for childern. Traditional games which are commonly played for competitions can potentially developed into educational games. The Gotong Royong Run presented here has been developed and modified from traditional game called Lari Memindahkan Bendera(Flag-moving Race). The game is intended for pre-school and elementary school childern to train skills of working cooperatively.
