How to play Slots

Easy, right? Well yes, originally slots were that simple, but they are a little more complex than that nowadays.

This page will give you all the information and get you started, explain basic and expert stuff followed by some amazing casino tips.

Slot machine anatomy

Classic slot machines have three reels with only one horizontal payline. Today’s video slots usually have five reels, multiple paylines, special game features and bonus games which gives the player more winning possibilities. These are the common basic parts of a slot machine.

Symbols are images that usually spin vertically. A symbol’s value varies, and usually the more rare it is, the higher the value.

Paylines are paths going across the reels, usually from left to right. Alignment of identical symbols on one or more paylines means win.

Reels are vertically spinning groups of symbols. When they stop, random symbols appear. Slot machines usually have 5 reels.

Spin is the button you click to start the game and get the reels rolling. Similarly, Autospin spins continuously for a specified time.

Coin value and Bet Level both adjust how much you play for per spin. Decreasing or increasing the dials will lower or higher your bet amount.

Paytable is a list of payouts on a slot machine. This shows how many coins or credits the player will win for each combination of symbols.

Winning in slots

Depending on how the symbols fall when the reels stop, you may get a winning combination. Usually you win by collecting three or more identical symbols in a row from left to right. The more paylines a slot has, the greater chance of winning, and the more complete a payline is, the more you win. How you win, and how much you win, is also affected by the various game features and feature symbols that most games have. Check the games’ paytable for detailed information on how to win.

Tumbling reels

These are also known as Avalanche feature / Cascading reels / Dropping symbols. As line wins are awarded, the winning symbols disappear, causing symbols from higher up on the reels to fall down into their place. This creates brand new possibilities to win big without risking any additional credits.

Multiplier is a feature that often is combined with tumbling reels. The multiplier simply multiplies your respin win. How many times depends on how many wins you win in a row.

Free Spins

Free Spins are usually triggered by the combination of so called "Scatter symbols", but sometimes in other ways. During these rounds, some more perks can be given, which usually means bigger wins than during the classic gameplay.

Expert stuff

Once you’re familiar with the basics of slot machines, it’s time to take it to the next level. Here are some more advanced slot terms you should learn in order to become a full fledged casino pro.

Hit frequency

Hit frequency is defined as how often a slot machine will have a winning outcome. A hit frequency of 10% means that 1 out of 10 spins has a winning combination. Machines with lower hit frequencies tend to offer larger wins when it pays.

Payback rate (RTP)

Payback is an overall percentage that a slot gives back to all its players. This percentage is usually around 90-99%, depending on the slot.


This basically measures the size of the winnings. Low volatility slots will give you lots of little payouts often, whereas slot machines with high volatility work the other way around.
