We have been having an issue with the Game of The Week recently - and Roy has updated the Arcade to resolve the problem.
We are bound to have some teething problems - so please bear with us while we iron out any that arise.
It appears that if you run a game when your browser is in full screen mode, you may get a small game window that is not able to be resized. If you play a game when not in full screen mode, the popup window can be resized.
The updated arcade should enable us to install some games that will run on a phone or tablet - keep an eye out for them.
