Piggybanking.
There are many slot games that you can STORE your money in like a piggyback.
Say you hit a big win but you have a huge playthrough. So you can't cash out.
You piggybank the money for now, then make a deposit without bonuses. Now you have no playthrough. You play the games, collect your money. And now it's not attached to any playthrough...cash it out.
The casino still has the edge, there is still luck involved, sometimes it works better than others, but you can always save some of that money from going back to the casino.
One game that works well is Mobilots Ceasar.
As you play the jackpot meter rises, when it reaches $200 you collect $200.
If you have a playthrough you build the meter to $180-$190.
When you don't have a playthrough, you collect $200
