We've concluded not to put out a revenge challenge for FÄNGELSE. Feel free to still open a ticket if you think you've solved this in an innovative way, since nobody has solved it with the intended solution yet.

If you solved this challenge, feel free to open a ticket. We're evaluating to drop a revenge version. 🙂

The instancer for KONTINUERLIG will be down for maintenance
