From paradice island hd wiki;
hit the yellow/green buck awardsedit hit the yellow/green buck awards section

the best way to get them is to build 15 hotdog stands (you get an award for doing this anyway). you'll need to wait and watch for the buck signs ($) to appear, click the duck ($) signs as soon as they appear. wait again while watching the game, a little more than a minute or so later, the dollar signs will spawn in the order you clicked them again, leave them until they turn green and do it again. going for these awards will also help get you towards the repair/tax collection awards, and will gain a fair amount of money if you upgrade them in the early game. you may also want to build 15 cabins.

I think you're supposed to hit the yellow dollars when they first appear.

Answer from: Nicky
For every hundred times you hit the yellow or green dollar sign that counts as one towards the mission. so you have a ways to go.

It's not for every 100.

you just have to be fast. if you hit them right when they appear (for the gold) and right when they change (for the green), you'll see your counts go up.

and yeah, the best way to get them up is to watch those hotdog stands.

When they turn you have to hit them with in 5 seconds when there is a gun Target attached to the award it goes up.
