Pointless because steam only recognises up to 30 games as running.

Technically not possible to do it twice because the 3hour drop wait was put there to stop people from farming cards and refunding, after refunding the first time you can farm or you can refund, but not both.

So you can't get cards drops for the same game twice.

For example?

What does it say on your badge page for that game before the words "card drops remaining" - what number does Steam say?

fix it by refunding the games and buying again. Thank you very much for your attention

Sure if you don't mind getting permanently banned from Steam AKA that is a really bad idea.
Also, after you refund any game, steam changes the amount of time the first card drop happens from 5 minutes to 3 hours for all other games.

That didn't translate well.

This probably covers it:

If it's a steam game in your steam library with card drops then your badge page will show how many drops are remaining.

But if it's not a Steam game and it's an EA Play game in your EA library then that's got nothing to do with Idle Master, IM just idles Steam games.

Appdata is here:
C:\Users\%USERPROFILE%\AppData\Local\IdleMaster

A bit kludgey but you could close it, delete IM's appdata and then log in.
