Best Online Slots in America 2021

Every online casino player knows the excitement of playing slots. It’s no surprise that slots are the most popular casino game at online casinos in America.

The simplicity of the rules, the variety of games, and the flexibility of playing on any type of budget are what make it a game for every type of casino player. 

Whether you're looking for free spins, bonuses, jackpots, free games, or just want to know how slots work, you’re about to learn all you need to know about playing online slots to win.

Why Play Online Slots and Is It Safe to Play Them? 

Are Online Slots Safe to Play in America?

Online slots are legal and regulated at a federal level in the United States. Right now you can play at an online casino legally in either New Jersey, Pennsylvania, and West Virginia. 

Random Number Generators

Modern-day slots are controlled by a random number generator (RNG) which is used to generate completely random number combinations. This controls the payback percentage for each slot machine. 

The RNG is programmed to have a specific payback percentage for its respective slot game. Usually, the more money the machine requires per bet, the higher the payback percentage will be. 

What Are Online Slots? 

Online slots are the virtual version of your typical slot machine and are the most popular online casino game on the web. These gambling machines have three or more spinning reels that display symbols.

The goal is to spin the reels and have the symbols match up to form winning combinations. In order to play, you would place a bet, spin the reels, and hope for the best possible winning combination.

Why Play Them? 

85% of online casino gamblers play slots nearly exclusively. Slots players are in luck when it comes to online slots. This is because:

  • Much better RTP on online slots (with many games at 98%!)
  • Generally higher jackpot payouts
  • Big bonuses available to claim
  • No need to wait for a machine
  • Huge variety of games 

Now with new casino technology, slots can provide even more entertainment for players and a much greater abundance of games with exciting graphics and special features.

Modern slots are the biggest draw toward US online casinos. 

Did you know?

RNG payback percentages are rarely ever changed due to the amount of work it requires to make these revisions. 

Slot Games that Fit Your Style

What to pay attention to when choosing a Slot game?

1. Theme 

You can find a number of slots to play just based on the theme of the game. For example, some slots will be based on a certain type of animal, like Cats, or maybe a rock band, like Guns N' Roses. There are even slots based on classic movies, like Baywatch! 

There are so many different themed slot games, it would be difficult for a player to not be able to find a slot that fits their style. 

2. Lookout for volatility

Learning about the volatility of the particular slots titles will show you how frequently you can expect the slot to payout.

A game's volatility refers to how much risk is involved with that game title. 

If you are aware of the volatility of the particular slots you wish to play, you will have an idea of ​​how frequently you can expect the slot to pay out and how to win on slot machines. 

Low volatility slots will hit frequently but have lower payouts, while high volatility slots will hit less frequently, however, will payout in much higher amounts. 

Right in the middle are medium volatility slots. These will pay out more often than low volatility slots but with smaller amounts compared to high volatility slots.  

3. Pay attention to RTP

RTP refers to the funds a player is expected to win back from a certain game over a predetermined amount of time. 

This percentage is a theoretical number usually used as a reference. The average RTP rate for online slots is 96% however, some online slots have extremely high RTP rates.

Types of Online Slots

You're going to find a huge selection of slots at any online casino you visit in America. These most commonly range from 3-reel classic slots, 5-reel video slots, and jackpot titles. 

Let's take a look at each one below. 

Number of Reels

Most online slots feature 5-reels, however, there is still a great selection of 3-reel slots as well. 

3-reel slots tend to be the most simplistic out of the bunch and will feature one to three paylines. 5-reel slots tend to be much more animated with numerous paylines available.

  4. When you're finished, you can choose to withdrawal or exit the game instantly. You will not lose your winnings if you leave the game.  

Now, every online slot will feature paylines, symbols, and reels. However, a lot of slots even go the extra step and add features like wild symbols, scatters, and bonus rounds, to make the game more fun for users.

Let's take a look at what some of this stuff means:

Paylines

In order to win, the player must match the symbols along an active pay line.

Wilds

These symbols are found in slots games. They can be used in order to create winning combinations. Wilds come in different forms including:

  • Expanded wilds, which cover an entire reel.
  • Walking wilds that move around from reel to reel while the player spins.
  • Sticky wilds, which stay still and remain on the reels for a certain number of spins.

Scatters

Normally, landing scatter symbols are what unlock the slots bonus game or it's going to pay out a large amount of cash. You'll need to hit at least a couple on the same payline, or it just acts as another normal symbol. 

Bonus Rounds 

Bonus rounds are an exciting feature offered by slots that allow players to increase their winnings substantially. You'll need to land certain symbols on the payline (depending on the slot) to unlock the bonus game and then will usually get a select amount of free spins to use.
