Mario Royal is available in all modern web-browser, for free. You can play it right here.
Epic Games announced that they are separating console players from mobile players for “better per-game experience”. Which means Xbox One and PS4 users will have their own pool and so as Nintendo Switch, iOS, and Android players have their’s.
However, if players are already in cross-platform parties, this will not apply. Making cross-platform play across all platforms still available.
