Slots are a type of casino game that involves spinning reels to activate symbols and win credits. They are available at many casinos and can be played in a variety of ways, including online. The best way to find a slot machine that suits your needs is to read the pay table and other instructions on the game.

Payout percentage

The payout percentage of a slot machine is usually posted on the rules or information page for the game itself, or as a list on either the online casino or the game developer’s website. This is important to check if you are looking to play slots for real money or for fun. If the percentage is higher than you expect, you should avoid the machine.


A paytable is a detailed explanation of how to play a slot machine, usually located on the machine itself or in a separate book-like booklet that can be opened by pressing a button. It contains information on paylines, betting requirements, and jackpots. A paytable may also provide information about special features, such as wilds and scatters.

Bonus rounds and free spins

Some slots offer bonus games, which pay out when specific combinations of symbols appear on the reels. These games are often linked to other slots, and can increase your overall winnings.

They can be activated by a special button or lever, or with the use of a touchscreen, depending on the machine. The player inserts cash or a ticket with a barcode into a designated slot on the machine, and the reels then spin to reveal winning combinations.

When the machine stops momentarily, it will re-spin and rearrange the symbols until one or more combinations appear. Typically, each reel contains five or more symbols. The combination that wins is determined by an RNG (random number generator), which generates random numbers within a large spectrum and decides the outcome of the spin.

The reels may be arranged in rows or columns, and the positions of the symbols on each row are determined by the number of coins inserted into the machine. The highest paying combinations are shown on the top rows of the paytable.

WILD symbols

A wild symbol is a symbol that can substitute for other symbols in the reel combinations to complete a winning combination. It is a common feature in video slots, and can result in a huge win if the symbol lands on the center three reels.

Bonus rounds and free spins

Most slot machines have bonus features, such as free spins and multipliers. These can be activated by collecting three or more scatter symbols, and they can award a variety of prizes. These can include extra spins, multipliers, and cash prizes.

They can be played on desktop computers or laptops, but most casinos now have apps and responsive websites that allow players to play slot machines from their smartphones. These apps are easy to download and can be played for free or for real money.
