The Noble Path what is this?

I was researching to figure out the same thing and somehow ended up HERE! .Following.

So in the noble path you win energy to play Bubblegum Hill. But is it correct that any energy you win will expire at the end of the day? That’s what is happening to me. So you cannot try to collect energy by winning it to play Bubblegum Hill more than once a day without buying it. Unless, of course, you have enough levels to play so you can win 100 energy in one day which is really hard to do. Why can’t the energy you win carry to the next day?
