Also related to the security issue is that when going to the PWA game's URL in the first place you may be asked to 'Continue to the web page (not recommended)' - in fact, it's safe. Hopefully the developer can fix the certificate issue in short order!
From the (super short) Appscope listing:
Tap scramble and move the tiles back into alphabetical or numerical order.
The URL to tap on or type in is loopover.xyz
Of course, you can turn this into an 'app' yourself with PAWA or just pin it 'as is' on your Start screen. Or just add it as a 'Favourite'. It's up to you. If you're confused by the different PWA options then check out my feature here.
Here's the PWA game in action:
A game in progress - it's a veritable 2D Rubiks Cube and tremendously well done; (right) not only dark mode and animations control, but even a way of exporting your solutions. All very sophisticated.
When starting a new puzzle, there are eight square grid sizes, or you can go rectangular - obviously (right) if you go beyond a grid of more than 26 items then you get switched to numbers!!
