Offer wall game questions

I have a couple simple questions. So I was looking on an offerwall and the offer was a play to earn offer. It said in the details that you can play or earn up to 112 points per day for a session for 30 days, but the confusing part is it also says offer is 900 points. So does it stop accruing once you hit that amount or is that in addition if you complete all 30 days?

My other question is when I open the game to play it can I just open it regularly from my phone once I’ve done it the first time and allowed tracking?

Thanks!
