Pokies games, like every other game, can be downloaded from the App Store on iOS devices and the Play Store on Android devices. If you use a casino’s pokie app, you’ll be asked to sign in the first time you use it, so you shouldn’t have to do so again. Only make sure that if you wish to play for free, you pick that option when you launch a pokie – you don’t want to waste the whole real money balance unwittingly.
