Steam cards bugged out?

I only got 3 cards and it stopped dropping them

So all of you managed to DDoS whole Steam down by starting and stopping your games all the time just to get 1 card!

Steam is up and the next thing in idlemaster still works.

Oh boy I'm too lazy to do it still, and for some reason i don't want :P
I mean steam is all about idling cards and collecting games what's the point in catching the carrot if the real goal is the chase itself :P

I noticed that too. 5 minutes in-game, closed it and I got a card. But then if I run the game and close it right away it doesn't give me another card, I think I have to wait a few minutes before it drops but yeah, they drop a lot faster if you run/close the game every few minutes.

Still working ?
