• Staff help, not supervise: play workers are on hand for games, crafts or emergencies, and kids can leave without signing out
• Limited access for adults to parts of the playground, since the space is built around kids playing on their own
• Evenings for ages 11+ on Wednesday and Thursday, 6pm to 7:30pm, outside school holidays

Robi Allmend is a staffed adventure playground run by the Basel association Robi-Spiel-Aktionen. Kids roam an open play ground built for adventurous games, use the workshops for building and crafts, and hang out in the indoor play rooms. Special days bring donkey rides or a BMX race on the playground's own bikes.

Kids come and go freely. The play workers help with games, crafts or a problem; they don't supervise.
