This will depend on various factors including the type of websites and the technology used for the games on the websites. Some websites may contain a message or disclaimer that the games may only work based on computer requirements. If Flash is required, when you try to launch a game, you may receive an error that Flash is not longer supported or is not available. The best thing to do is contact the website or manufacturer of the game(s) and inquire if they will be providing updates for the games to run properly due the change with Flash. If manufacturers receive enough requests, they may consider upgrading their game websites. If you are the creator of the game or have access to the source file, check the originating program used to publish the game to determine if alternative outputs are available instead of Flash so that the game can be re-published. More often though, a game or program may need some editing or re-coding before it can be republished or upgraded.
