This is the one. The first interactive play set around the world. At a primary school that has active play as one of the main focus points of their education programme. A very enthusiastic team of teachers and pupils still enjoy playing the games every day. After the grand opening a lot of new games were released at this schoolyard, and a lot of children spent their play hours playing games like Freeze, Codebreaker and DanceBattle.
