To be a good slots player you should know some basic slot terms. It is vital to know basic slot language whn entering a casino (land based or online).

RNG Random Number Generator : it is a computer chip inside the machine, which job is to select hundreds of random numbers and symbols every second. The chip is very fast and it is working even when noone plays the slot machine. Every number is related to specific symbol combination that is randomly chosen when someone plays the slot machine. As you can imagine the smallest number of combinations represents jackpots. This program computer chip is also designed to determine that particular slot's average payout %.  No slot machine will pay back its preset payoff percentage rate every time. Because the final outcome of every spin is randomly selected.

Reels: specially made wheels/reels with symbols on them. Mostly there are three reels, sometimes five.

Slot Schedule: this is the basic slot information, it should be placed at the front of the slot machine. Describes the slot type, denomination, and win ammounts for each combination. It is important to read this information before you start playing.

Loose/Tight slots: Loose slots will have better payoffs to a certified high of 100%, on average over a period time. A machine will have a symbol; let's say 2-3 cherries, which pay a couple of coins. These cherries will replace a symbol that doesn't pay, and presto you have a loose machine. Reverse this procedure for a tight slot. In other words, the more paying symbols a machine has, the greater the probability of payouts - thus a loose slot.

Up/Down Slot Cycle: Slot's average payoff percentage rate applies over the long haul, as long as one year.  Therefore, a slot with a 98% payoff percentage rate will sometimes pay off at 130% and other times at 50% … sometimes at 28% and other times at 502%. The lower percentages indicate a down cycle and the higher number an up cycle.  Also known as Sizzling/Sputtering Slot.

Slots Drop/Hold: Drop the ammount of money that goes through the slot. Hold the ammount of money that is not paid as wins (stays in the slot machine). These two determine slot machine's payout percentage.

Slot testing: it is a kind of planned palying strategy. One may test the slot in order to find out the possible payout percentage for one particular slot machine.

Slot-mix or Slot Placement: the loosest slots are placed in high-traffic areas where other people can see other players winning often. Important to analyze a slot's location, in other words - crack that slot-mix code - start at the main cashier/change booths in the casino. Don't play two machines at a time, side-by-side; tight slots are placed next to loose ones. What one giveth, the other taketh away. Remember not to play next to the winning machine. If someone next to you wins, try to find another slot machine.

Slot Types/Versions: regular slots (flat-top slots) have a predefined jackpot level which is constantly the same, no matter how much the machine is palyed. Multiplier Slots pays for certain symbols on a graduating scale. On a three reel, you get 5 coins for a cherry playing 1 coin, 10 pay for 2 coins and 15 pay for 3 coins. The payouts for playing 1 coin are much smaller than if you played maximum coins.
