First, go to the "Earn" tab and answer the daily poll question, then touch the green button that says "Earn 10 sats" to run an ad. I think we get 5 of those every 12 hours. 

Then open the "Game" tab and install any of the games powered by ZBD at the bottom. Pick something you find interesting. I like Spacey and Bitcoin Miner. Link ZBD to both to withdraw sats from the games. 

Lastly, I've noticed my sat balance going up on full passive. Looks like we're being paid an interest rate of some kind. It's not much, but you'll start to see it yourself with a balance of 2000 sats or more.

I hope this helps.
