We cant play any of the versions of the game anywhere but cool math where do you find a non-flash player version of the game. (since flash has ended and none of them work now)
If you look in the resources you will find a couple of downloads. One of them is for an offline flash player, which works fine, and a .swf file for 60 seconds burger run. All you need to do is download them both, open adobe flash offline player, and then open the .swf file with the flash player. Also, I'm not sure if anybody else has this issue, but I have to set the quality to high otherwise I constantly clip through every wall possible.
There is now a Practice Mod for the Flash version of the game "60SBR_IGT", created by Sage (Zeekza). This allows you to replay and time individual Levels. You can find it as part of the Burger / Santa Run Collection
