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 a bonus that a live casino offers players for continued play at one of their machines. It can take the form of free meals, shows or even cash rewards. The percentage amount of the house edge indicates how much the casino wins from every bet 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.
