Why can't I run any Java or Flash sims on my iPad?
iPads do not support Java or Flash. Only the HTML5 sims are compatible with iPads. You can see the compatible sims here.
How do I run an HTML5 sim offline on an iPad?
We offer an iPad app that allows native offline use of all the HTML5 sims. Find it on the App Store here. Our app is $0.99 and proceeds fund more HTML5 sim development.
You can 'Download' an individual sim to use on an iPad (offline) by adding it to the iPad reading list.
