This question already has an answer here:

When playing a Steam game that supports Trading Cards, you can receive a certain amount of trading cards which you can use to craft badges or sell on the Steam Market.

Does Steam give away these cards randomly, or do they give it away at set intervals (Ex. every hour a new card is given)?
