As the title?

Is it possible to run a browser game off line?

Maybe, depends on the website and how it is setup.
In your browser, try File menu, then “Save page as”. Then choose the option for “Web page complete”. That should save the webpage, and any flash files and images etc that are required. So you should be able to open that page offline.

Though I think most websites will be designed to stop this, as they want you to look at the adverts etc. So it may not work.

You can check the source code for the page and look for the .swf file which you can then open in a new tab and the save.

If it’s a very simple game the above technique(s) might work, but generally no.

I used to work for Miniclip and all of our more sophisticated games were set up such that they wouldn’t work except on our site – that was more to stop people ‘hosting’ our games on their own sites and creaming off the ad revenue themselves than to stop people playing offline… but in general the company that made owns* the game wants you to play it on their site in order to make money off you one way or the other.

*Miniclip used to make a lot of its own games, and it was fun… then the strategy shifted more towards buying them in and rebranding them (e.g. the massively popular agar.io which was ‘talent-spotted’ and bought)

Get Chrome and then install this..
