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. 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 casino is mathematically guaranteed to win over a long enough period of play. If the House has an edge of 5 percent on a particular game, they will win five cents over every dollar played at that game over a long enough 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.
Persistent player.
The players of this type believe that very soon there will be a period when the machine begins to pay. The machine can begin paying in any second.
Players become so persistent if they have already spent a lot of money for this slot and haven’t got anything or if they have found a slot machine that haven’t paid for a long period of time. They believe that a big win is sure to happen right now. They can’t leave the machine because as soon as they do it will burst forth and pay out large sums. Makes sense if you have lost 0. 00 and have yet to win. The machine must pay.
In the old days when a payout occurred players would feel the coins to see if they 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.
The second type of slot players is a chaser.
The player have won and being reinforced by the win gains trust in the slot machine. There is some kind of comfort and trust between the slot machine and the player.
