how play on chromebook
Depends if it is owned by a school you are screwed since they can access your browsing history even with Incognito mode which also means you are probably too young to even play this game (which means you are in really deep shit).
If it is yours, you need to spend $5 for the apk and sideload it into the chromebook. WARNING Chromebooks can be temperamental with unofficial apks and the game might not even work properly on it or not at all.
