Why does the game exit fullscreen after a few seconds?

Dude, sorry to hear that. That fullscreen stuff is such a headache. Either your browser isn’t doing its job properly, or the game is messed up. Try upgrading your browser (I know, you think you just did that but try anyway), or test another browser like Chrome, Firefox, or Edge. Old-school casinos often rely on Flash or other old technology that can get buggy. Clear your browser’s cache and cookies as well. Ensure your video card drivers are up-to-date. The problem may be with the game, which might have a policy of automatically logging users out when they play at a particular resolution. On a mobile device, it could be the browser’s fault. Contact customer service with details about your problem; sometimes they can help or will acknowledge it as a known problem that they’re fixing. Hope that helps!

The fullscreen flashing is usually a browser preference or an OS setting issue. Chrome does not play well with Fullscreen API if you don't have the browser settings right. First try updating your graphics card drivers - that solves 80% of these problems. Second, look at the game's support forum; some games intentionally restrict fullscreen access to prevent cheats. If it is only this website, comment below and we'll try to fix it.

That is almost always the fault of your browser or an add-on that runs in your browser. Try another browser (Chrome, Firefox, Edge), turn off any ad and/or script blockers, and see if things aren’t better. Some games force the window into “full screen” when certain buttons are clicked – look around in the game for a setting called “Keep Full screen”. And of course – you might want to update your graphics card driver. Tell us what browser you are using and we will try to figure it out.
