Every player must stick to his bankroll. Bankroll is the total amount of money you can afford to play with or to lose. 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. 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 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.

Know what you are playing.
Always make sure that you insert the correct amount of coins into a machine. Your credits should be cashed out before you leave the machine.
Just have fun. Slots should be fun, not stressful. You can increase your bets only when you are winning, and decrease your bets when you are losing.
