• A parent joins under-13s inside the room, and parents are asked to stay on site for the whole game
• Not designed to scare: the rooms are exciting rather than horror, and staff can soften lights and sound for younger kids
• Free parking out front on weekends and on weekdays after 7pm; before that it costs €2.50 an hour

Backspace runs a set of themed escape rooms near Sloterdijk. The Time Machine is built for children: 8 to 15 kids play as one team, splitting into small groups to crack puzzles and fix a broken time machine, with a game master in the room giving hints.

Families can also book Budapest Express or Mindcrime, where staff turn the lights up and the sound effects down for younger players.
