Every player must stick to his bankroll. Bankroll is the total amount of money you can afford to play with or to lose. There is a bet max button on every slot machine. Bet Max button allows you to play with the maximum bet on this very slot machine. If you have been playing one and the same slot machine for some period of time, you will be rewarded with casino comps. With these comps you can get free meals or even cash in some casinos. House Edge is an amount the casinos is sure to receive over a long period of time. Payback is percentage amount of each bet dollar, that is paid back. If you play the slot machine with 86% payback it means that it pays back 86% and 14% is the house edge. Remember that these amounts are taken over a long period of time.

There exist at least two types of slot players.
The first type is a persistent player.
These players are sure that the machine is already ready to pay out, they just have to wait for a little. Just a second and the coins will be flying all over the casino!
The player will play until the machine pays out. He must have found a machine that haven’t paid for a long period of time or he has inserted to many coins and has got nothing. They believe that at least any payout is due to happen. The rush is that if they leave after depositing so much money in the machine it will erupt and the payouts will be often and large. Maybe it can really work if you have already spent thousands of dollars and have got nothing back. The machine will pay any way.
Many years ago in the case of the payout players touch the coins to check whether he coins were hot or cold. If the coins where hot then the slot machine had not paid out in a while and to the chaser this was good as the machine was do. The heat of the machines lights, etc would eventually heat the coins.
Chaser is the next type of slot players.
The player thinks that the machine he is going to play is not a machine that never pays. The player have won and being reinforced by the win gains trust in the slot machine. A sense of comfort exists between the slot machine and the player.
