How can I increase my sats through gaming. I'm not getting rewarded for my playtime. One game said I've earned 680+ GPUS and asking me to sell them for less to help their miners but not showing how to redeem them for points ar sats?

Hold what I can't get any sats

Can anyone tell me how to increase my Sats I've been playing this bitcoin game for at least a year and still don't have any sats. What's the purpose of the gaming if not rewarded properly.
