i played cookieclicker on my Phone a lot, untill it got very inaccessible.
For the version wich can be played in your browser, i tested a few things, and i found with using Firefox in combination with nvda is working on a acceptable proportion.
To click the image of the cookie, it is a clickable element. i thought the first one you will encounter when entering the section where the game is displayed. But i am not 100% sure if buying upgrades works that well.
I am personally very interested in idle/clicker games on IOS, so if someone have some recommodations for the ios platform, i would be very greatful.
I know of the universal paperclips app on ios, wich is rather fun, become the greatest manifacturer of paperclips around the globe
Hope i have helped a bit, and hope to hear from someone soon.
