Spending most of the time on the couch after knee arthroscopy and being smartphone-dependent I have discovered Mekorama.
Very good puzzle game, freeware and devoid of the freemium nonsense.
The goal is to navigate a robot through a series of 50 rotatable playing fields and help him reach the exit. There's also plenty of fan-made levels.
