He's probably getting some sleep, so I'll jump in.
AWP stands for Amusements With Prizes..
Online slots are random, so no matter how much you win or lose in any particular spin, the win or loss does not have an effect on the outcome of any of the next spin(s) you might decide to take.
Compensated games (example; fruit machines that can be found in arcades or pubs in the UK) are designed to meet their advertised RTP depending on how much the machine the machine has taken, or how much the machine has recently paid out.
If someone has had a jackpot on a compensated game, or a few half decent wins in quick succession, prior to you playing it, the machine will visibly tighten up and simply refuse to offer the chance to get similar big wins until it has recovered enough back that it can once again afford to do so.
Likewise, if someone has just lost an absolute fortune on a compensated game and then you happen to luckily play it after them, the machine will likely be wanting to pay something back out , to compensate for all the money it has taken from others up to that point. It has to do this in order to keep consistent with the targeted RTP.
In general, this means that if you play a compensated game for long enough and keep getting nothing back - or irregular, tiny amounts back in return, the game will at some point begin to want to pay out bigger wins in order to compensate for all the money it had previously been taking.
So, essentially, you could play a compensated game and collect nothing while doing so, losing money, until it eventually starts becoming visibly more generous, offering bigger and bigger wins, perhaps even offering the jackpot at times, because it needs to do so in order to level the RTP back out to nearer its target. The more it takes at that point, the more it will be trying to throw something big back in order to compensate.
A random game does not care how much it has previously taken, or how much it has previously paid out. You could (lol) theoretically get a 5000x jackpot win roll in 5 times in 10 spins, 2 sessions in a row. And so could the next person who plays it. And the next.
But, a compensated game does care, and so if a compensated game has paid out 5 jackpots or something crazy, it will tighten up like a rock and quite literally refuse to let anything substantial back out until it has taken enough that it can afford to do so. Because it is designed to aim for a targeted RTP. Though this cycle varies dramatically depending on the game and how it is designed.
All games will have in the information/help screen a statement that either says "this game is random" or "this game is compensated."
I'm tired as hell, so I hope that makes sense.
