I've been using the Ember Fund app for some time now, and they have recently done some updates that are quite nice regarding the application as a whole.

If you are unfamiliar with Ember, you can do many activities related to investment and satoshi earning.

Activities include

-Adjoe gaming for simple satoshi earning.

-Predictions

-Portfolio investment options maintained monthly portfolios for users to invest in.

-LN chain compatibility in the works!

All in all my experience has been great with Ember, customer service is excellent and I've earned a great stack of satoshi. I recommend this to anyone looking for one if the best sat stacking resources out there or a good way to practice investment decisions in a free tournament.
