Yes, it idles 30 games at a time. People have been idling 30 games at a time for years, haven't heard any complaints from Valve. It doesn't make any difference to the steam servers whether you idle 30 games in a row or 30 games at once - it's going to be roughly the same number of calls to their servers either way.

So long as you install the steam client then you should be able to use steam-idle.exe from idle master extended v1.3, see other posts mentioning steam-idle.exe

IDK, use idle master v1.3 perhaps

Actually I missed that update, 1.3 still does work fine.

Idle master extended does not go to 1.4, it goes up to 1.3. make sure it is idle master extended and not plain idle master which doesn't work any more.

No, Idle master extended, steam client needs to be running and logged in with an account that has the game you are trying to idle or family sharing set up with the game.

In the shortcut properties target line use inverted commas like:

"C:\Users\me\Downloads\idle_master_extended_v1.4-final\idle_master_extended_v1.4\steam-idle.exe" 230290

Maybe try putting im-extended folder somewhere outside of windows weird directory places, like make a folder off of root and put it all there.

Does work, steam-idle.exe is in the same folder as the main program. I used it yesterday to do the spring cleaning badge.

This has very varied results from one game to the next and from one user to the next. It very rarely ever works for me. It seems that some unknown conditions need to be met before it'll work. Idling 30 games at a time is quick enough for me in IM extended fast mode - Archi's steam farm only idles 1 game at a time (unless it's changed recently).

I can only guess the things that can effect card drop frequency, it could be amount of time since the game was last played, amount of hours it was played previously or some other obscure metrics I'm unaware of.

The other thing is Valve servers get bitchy if you access them too much, for example I see errors if I look at too many steam market item pages too soon or if I visit too many store pages too soon. There are cool-down triggers to prevent over-use all over the place and the last thing we want is more http 500 errors being applied or Idlers getting blocked completely. Worst case scenario is your account getting banned, not worth risking.

Idle master does not give you cards, steam gives you the cards. Idle Master reads your badge page, it looks for the words 'card drops remaining' and it then tells Steam that those games with drops remaining are running until steam gives you the cards.

If you think the software is not working then you are free to launch the game and wait for the cards to drop. Check your badge page first http://psteamcommunity.yuanyoumao.com/my/badges
