Go to "Settings" Then Search Up "Linux" Then Download the linux installation. Wait for it to install, (Requires some space open.) Then download the zip file and extract it. Then go to google and download the latest verison of wine, which is a linux mod or whatever. Then install it to your linux on your chromebook. Then figure out how to get wine to find the exe in the directory of the game folder. Then have wine execute it, it will be super laggy though. It might have some errors, as the dll files maybe not working, it crashing (maybe because of wine.) or any other issue. I do recommend getting a windows device though.
