You may have connectivity problems or loading issues. We recommend that you exit the game, clear your cache, close and re-open your browser, and try to load High 5 Casino again. We also suggest not having multiple browser tabs or browser windows open, as this can interfere with loading the game as well.
You may also want to try rebooting your router, as this can sometimes increase the speed or your internet connection. If none of this works, you may consider re-installing your Flash player. To re-install your flash player, please go to this link: http://get.adobe.com/flashplayer/
