My iPhone and my iPad are logged in with same Apple ID i already purchased on my iPhone but I can’t find it on that list “purchased items “ and my iPad’s App Store showed I still need to pay 6.99to get this game one more times I want to know is this correct?
No, for iOS and iPadOS you only have to pay for it once. Any time there's a purchase issue like this, just contact Apple Support who can view your purchase history and fix it for you.
