Standalone, Windows 10:

C:\Users\YourName\AppData\Roaming\Macromedia\Flash Player#SharedObjects\Assortment of Numbers & Letters\localhost\ Go to the same folder you put the standalone .swf file.

Run3.sol is the savefile, to reset the game you have to delete it every time or when you have a clean file go to properties and select "only read" mode, in this way every time you re-open the game it will be resetted.
