Bankroll is the amount of money you have designated for gambling. Keeping your bankroll separate from your personal finances is a good way to avoid gambling 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 casinos is sure to receive over a long period of time. Payback is the reverse of the House edge for slot machines. The payback is how much a slot machine gives back for every dollar it takes in. If a machine has an 85 percent payback, it pays out 85 cents for every dollar it takes in; therefore, the House edge on the machine is 15 percent. Ideally, a slot machine you play will have no worse than a 90 percent payback, especially if you play slots online.
