Using the same trick of editing KoboReader.sqlite as worked on the Glo HD, it's possible to reveal the "missing" beta features on the Aura One.
Solitaire (all variants) seems to work fine.
Unfortunately Sudoku and Sketch Pad don't. Sketch Pad doesn't clear the screen and Sudoku - the one I really want - just doesn't display properly.
Clearly it's got scaling issues (and I wasn't surprised to see that) but does someone more able than me think there might be a mod to the firmware that makes sudoku work with the higher resolution screen of the A1? It's interesting how Solitaire is fine - it must have been coded more flexibly.
I do like the odd game of sudoku on the Glo and it'd be wonderful to get it working on the One.
Thanks
