Generally, not speaking of how the experience is playing on the devices, ( well it could effect experience). But why do they offer such different random options players can do?

For example. IOS graalians offers their players the ability to receive Graal PMs as a notification to your phone. While having trialpay.

PC makes you buy (recalling from memory could be wrong) you must buy the ability to even have a house for 2500 while mobile gets it free, and also need to pay to change body colors I believe or access hats. But does have trialpay.

While Android does not have trial pay. But also doesn't seem to have any special features or tools, cannot even get pms from Graal to your device's notification bar when your off Graal.

The question though is, why is there so much differentiation between the three. Furthermore why does Android not have trial pay? And why does PC have to make players have to pay to access hats,house, change body, ect?

Also do you think there is a valid reason for allowing players to so certain things while the others aren't allowed to despite being more than capable of such?

I don't think there is any main purpose, maybe some things can be done on one device but not on the other. PM notifications is a good example.

Why does ios have more in app purchases and the others only have the gralat packs.
The other devices are outdated and still say eurocenter is the publisher.

Only ios has the + editions and ol'west isn't even on amazon and probably never will be.

One could logically assume that, But actually Android is fully capable of trial pay, it is more than capable of receiving PMs as a notification anything really IOS is capable of really Android also can do. And realistically setting up something where PC players don't need tipsy to use their hats and change body colors is also possible.

Android only has the + version

ANDROID SPARRING > APPLE/PC SPARRING
just ask my boi Kaios XD

I do feel sparring on Android is a bit better, I had less issues on Android than I did on my iPad or iPhone when I used iOS devices,but PC I think is a bit better if due to people typically get better agile wise on PC

well I'm assuming that android has not got trialled is because it's App Store isn't as secure as the iOS one. You can easily get many apps that help you cheat on games on android whereas it's practically unheard off for the iOS App Store.
I'm guessing people could probably get apps to skip the trial pay service and make it seem as if they completed the task when in fact they haven't? That's just a guess I don't actually have a certain answer.

If that was the case, PC wouldn't have trial pay, anything Android can do PC pretty much can to and more, You can even download a rom or emulator on PC that will run an Android phone on your PC, as well as probably iOS emulators as well.

Different platforms, different complications.

why does FB only get u 20k for 10 bucks and not 27.5k

In the UK it's equivalent to:
27.5k for $13 with in-app purchases
20k for $10 with superrewards
20k for $10 with facebook
12k for $10 with trailpay through subway cards (?)

Better question: why do I spar better sitting up than I do laying on my back

your arms will feel less constricted when you stand
