We have mainly thought of inöuqa to play and move indoors. But when the nice days arrive, we understand that it is tempting to move it outside. So, it's possible, with some slight reservations and precautions however... Your units will resist to different weather, but it's probably better to avoid heavy rains which could insidiously infiltrate the plugs with the magnets. For playability, you will need to find a flat surface, which will allow you to have stable constructions (avoid the lawn for example). And the most important thing in our opinion, is not to leave the units outside. We recommend bringing them in after each use to preserve them and make them last as long as possible. But we have a little secret to tell you: we are already thinking about a special outdoor magic playhouse.
A little patience...
