So I have a question about how steam cards work, specifically if there is a limit outside of the random factor to the card drops. So I know you can only get half of the cards total by just playing the game, but I am experiencing an issue where I have been idling in 13 games for the past 6.5 hours and haven't received a single card for any of them, even though I just installed them all for the first time (Meaning I have all my drops available). So is there a limit to the amount per day, because that would explain why I am not earning any. Any ideas?
Best Answer
Personally I found running many games at once does not work for me, I have gotten cards when it was 3 or less games at once.
Cards generally drop once every 30 minutes for most people when playing a single game I am unsure if this average stays the same when using multiple games.
I do not believe there is a limit to how many you can obtain in a day since there is a limit already associated to the total amount you can have.
Things to keep in mind
Level 10 you start getting foil cards.
Every 10 levels you increase your chances for booster pack by 20% at 100% it has (doubled)
