Daily Puzzle vs iPad


Thats about all you can do, otherwise you asking a question that no one can really answer. Only chess.com can. Hope they read this....

I concur. Puzzles should work (in the default browsers) on iPad and iPhone and Android. They currently work on none of these devices.
I've sent a suggestion to admin already with no response, so I'll mention it here. I really think, considering the number of us who play here on tablets like my iPad, that the Daily Puzzle should be playable on these devices. Practically every other part of the website can be accessed. Why not this feature?
