How do I toggle between full screen and windowed mode in online casino games?

Depends on the game, browser, and platform. Most games allow you to toggle fullscreen/windowed mode without exiting the game. Look for a fullscreen icon (at top-right of the game screen), press F11 (Windows) or Cmd+Ctrl+F (Mac), or, if your browser is in fullscreen mode, exit that. Some software platforms, such as Playtech and Microgaming, provide a "Window" option in the game settings. Right-clicking an HTML5 game should bring up a context menu allowing you to toggle fullscreen. Flash-based games are more problematic. If none of the above works, just exit the game and re-launch it in windowed mode. Anything else I can help you with?

The vast majority of online casino games will let you toggle into fullscreen with a top-right button somewhere in the corner of the game. If not, look for an “Exit Fullscreen” button within your browser, or hit F11 on Windows (Ctrl+Cmd+F on a Mac). It varies by browser, however. Chrome and Firefox are different. Sometimes you’ll just need to exit the game and reload it. And sometimes the fullscreen option is found in the game’s settings, which many providers bury. Just try out a couple of things and you’ll figure it out. Cheers!
