It's not true 1:9 selection. It has been confirmed that you'll get what the bonus is once you clicked the card. So no matter what the card that you click, it doesn't matter.

The random bonus generator works by percentage. So you have a very big chance of getting the lowest money or food, and very little chance of getting the dragon, let alone the gem. I've at lvl 40 right now, and almost everyday clai, the bonus and never get the gems once
