As many as you have unique games to idle. If you have 36 games with cards you could run 36 idlemasters.

You could actually run as many as you want, but past this point of "I have X many games I can idle" you just start to double up and the program doesn't speed up anything by having multiple programs on one game.

That said the more games you idle at once the higher the chance that Steam will throttle your card gain and you'll end up with LESS cards-per-hour than with a lower number. So keep this in mind (personally I tend to just use 1 instance of the program which is usually pretty solid)

Okay thank you so much for the quick respons i appreciate it

another question that i have is

Will the program be able to " play " the games for me ( meaning more hours played ) ( equeals more games to idle )

All so what does the green bar indecate

Yes that is how the program works. It pretends to play the game so that you gain the cards. It has no effect on achievements although (except ones which trip based on time played).

Green bar is how many more cards it has left to idle. It's just a visual representation and really means nothing at all (the numbers shown are more reliable and precise). Ultimately it's just pretty.

Thanks agian man

But about the time thing. I meant will there be a feature, where the program can play games. Which have not been played, for more than 2 hours ?

All so what does this mean ?

30 idle, but it is not showing any game

HAHAHAHA you overloaded it! Well let it do its thing and it should start working again.

Since development on this program has stopped because of the owner's status changing, no there'll not be such a feature added. It always depresses me to mention this part to newcomers to the program.

Dang that was quick of me...

And yea i just figured out about the " situtation " it is kinda sad.

Thank you so much for helping me i appreciate it !

may you have a great day
