What You Need to Know About Slot Machines


A slot machine is a popular form of gaming that accepts coins, barcoded paper tickets, or cash. To activate the machine, players press a lever or button, which then spins the reels and awards credits based on the paytable. While symbols vary by theme and type, they usually include fruits, bells, and stylized lucky sevens. Each slot has a theme and bonus features that are aligned with that theme.

Payback percentage

There are two basic types of slot machine payback percentages: theoretical and actual. The former refers to how many coins the machine is likely to pay back. The latter describes how many times you can win one coin by playing a certain game. The highest payback percentages are most profitable for gamblers. But, they’re not always representative of the actual payback percentage. In many cases, they’re not at all indicative of the expected return.


Theme for slot games can vary greatly, from the common to the bizarre. Some players are drawn to games with specific jackpot levels or features, such as Gonzo’s Quest 2, which requires players to line up Mayan faces to unlock doors. Other players enjoy games based on a unique theme, such as horror, adventure, or ancient civilizations. The theme is just as important as the features or bonus rounds in slot games, so developers must choose themes that stand out from one another.


There are various types of symbols found in slots. The standard symbol represents the most basic of these. Another type of symbol is the wild symbol, which can replace any other symbol. There are also scatter symbols, which trigger free spin modes, and bonus symbols, which trigger extra games. These games are generally the most rewarding. Bonus symbols are often linked to the game’s theme. You may be surprised to discover that there are many types of bonus symbols. But how do you tell which ones pay out the most?

Weight count

A weight count for slot machines refers to the total weight of coins or tokens removed from a machine. The casino will typically assign a hard count team to do this. Wild symbols, which can appear on a single reel or all of them, will also count as part of the weight count, although they offer a lower prize than the jackpot and scatter symbols. Stacking wild symbols is also common, as they can take up an entire reel and make a winning combination more likely.
