The most obvious answer is that the games are new and her iPad isn’t. For some reason, people don’t seem to understand that tablets are simply another type of computer, and they can’t understand why a game released this year, say, won’t run on an 8 year old device and it doesn’t help that Apple doesn’t provide anywhere in the App Store description for developers to specify what devices their games/apps will run on. This then nets the developer a swathe of bad reviews.
Geri, I don’t think the games are the problem, I think the problem is that your iPad is too old to run them. Y’see an iPad is just another type of computer and, just as you’d not expect modern games and software to run on a very old PC, modern games and other apps won’t run on older iPads. Most games available on the App Store now require a device with minimum 2GB RAM, and some require at least 3GB. This means that devices older than the 5th generation (released in 2017) simply aren’t powerful enough. Crashing in my experience, is nearly always due to lack of available RAM, rather than storage space and, unlike in a desktop computer, the RAM in an iPad can’t be upgraded.
I’m afraid the answer is likely to be that, if you’re desperate to play these games, you’ll need to buy a new iPad.
If you tell me the model and iOS version I will confirm it for you.
