Bankroll is the amount of money the gambler is going to spend on gambling. It is wise to keep the bankroll separate from the personal finances. It will help you to avoid many financial problems. Bet Max is a button on the slot machine which gives you the option to play the maximum amount of coins the machine allows. This tends to speed up play. Comp is so called additional bonus, which is given to the player who has been playing one and the same slot machine for quite a long period of time. Comp can be represented by free meals and in come casinos by money rewards. 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 are at least two types of slot players.
The first type is a persistent player.
This type of slots player is the one that believes the win is right around the corner. Just a second and the coins will be flying all over the casino!
The player has either seen a person playing a slots game for a while with no payouts or alternatively they have been depositing funds into a slots game and haven’t yet seen any payouts. 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. Makes sense if you have lost 0. 00 and have yet to win. 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 were hot they believed that the machine had not paid for a long period of time. The heat of the machines lights, etc would eventually heat the coins.
Chaser is the next type of slot players.
The player believes the slot machine is not one of those machines that never pay. There is some kind of comfort and trust between the slot machine and the player.
