That´s quite a list! Thank you :-) I even have a few on that list and will try them out. I did not think about The Witness, but it´s worth a try. I did not finis it on PC, but it has some really hard puzzles in it that keep you occupied for a while at the same place without the need to move around a lot.
The Hexcells series is awesome, played through all of them (of course not through all the random ones in Infinite ;-)), but might be worth to try again on the tablet. I tried Tametsi (also a puzzler), but it did not scale with the High DPI screen and was super tiny.
