Start with the product type
Confirm that the selected Casino World title is social play and whether the route is browser, app store or desktop client.
Compare update handling
A browser uses the current web build; an installed app may require a store or operating-system update.
Check account continuity
Sign in with the same supported account before judging whether coins, level and collections transferred.
Protect the install route
Use the verified site or official store listing rather than an unsolicited package file.
