Real Money vs. Free Games

Having the free play option at your disposal is a fantastic way to get to know an online casino game; however, it never delivers the same thrills and exhilaration you get from playing for real cash. At all of our highly respected USA Online casinos, players have both options. They can enhance their skills and gameplay by practising for free on any of the best online slots and casino games, before transitioning to playing for slots for real money wins and jackpots. Here are the pros and cons for playing in either mode.

Real Money Slots

  • Players have the opportunity to play for real big wins, making the gameplay much more exciting overall - on desktop or mobile
  • Only real money slots players are eligible to play for huge progressive jackpots and bet multipliers in online slots
  • Players can expect the best and most lucrative bonus offers, plus free spins and additional rewards
  • Payouts aren’t always credited instantly, as processing times can take up to a few working days based on the casino
  • Players could be tempted to place large bets in some games, resulting in quick depletion of their bankroll

Free Slots Games

  • No signup or download of the casino software required - play immediately from your desktop or mobile
  • Practice your skills and get familiar with the games before spending any of your own real money
  • Play all the games anonymously with no requirement to enter any banking info or personal details
  • Players have no opportunities to win any prizes or play for progressive jackpots in online slot games
  • Players very rarely qualify for bonus offers or rewards when they only play for free at online casinos

The Different Types of Online Slot Machines

Slot machines have come a long way since the early days of the one-armed bandit. When slots went online initially, they were modeled on the classic 3-reel fruits and bars layout still seen in land-based casinos today. In the new internet age, however, online slots have evolved into several different varieties, with some even playing up to 7-reels at once. The latest ones sport even bigger prizes and a ton of paylines to wager on. You’ll discover the following most popular online slot machines at any of the online casinos we endorse. 


3-Reel Slots

These slot machines work with one singular payline and 3 reels for matching up winning combinations. Unlike other online slots, the 3-reel varieties do not feature any bonus rounds, and the lack of paylines means that the earning potential can be quite limited. They are, however, a grand reminder of the classic slot machine days and ideal for slot players looking for a play style that’s easy and familiar.


5-Reel Slots

5-reel slots are now the most popular type found in both land-based casinos and online. They tend to be much more exciting than 3-reels, with second-screen bonus rounds, wild and scatter symbols that help unlock winning combos, and free spins galore. 5-reel slots also work with more paylines, which gives players more chances to win and earn rewards in comparison to their 3-reel predecessors.


Progressive Slots

Progressive jackpots are highly prevalent in 5-reel slots. The value of the jackpot increases as more people play the game, which then deducts a percentage of each bet placed and adds it to the prize pot. Sometimes, this figure is capable of reaching into the millions, which makes these games so compelling and alluring to play. You must bet the maximum amount of coins to be eligible to win a progressive jackpot.


3D Slots

3D slots and i-slots are the latest innovations to hit online casinos and are particularly favored by those who play video games. These slots tend to feature their own individual storylines and 3D characters that interact with the player directly. While there are still plenty of rewards and cash prizes to be won, the real beauty is in the sharp graphics, audio, and cinematic animations with these online slots.

Different Types of Real Money Slots Bonuses

Welcome Bonus

Welcome Bonus

Welcome bonuses are used by online casinos to entice new players. These promotions typically include a number of free spins and are similar to deposit match bonuses. They also tend to include large bonus amounts and high withdrawal limits compared to most bonus offers. This is what makes them attractive.

Match Deposit Bonus

Deposit Match Bonus

Deposit match bonuses are just like welcome bonuses, apart from they typically come with a lower bonus amount. Casinos are always trying to compete for players when it comes to providing the best deposit bonuses, so expect plenty of variation between sites and some fantastic offers coming your way regularly!
Cashback Bonus

Cashback Bonus

Another popular promotion for players of real money slots casinos is the cashback bonus, otherwise known as getting a portion of your losses back. Online casinos aren’t quick to overlook loyalty, so it’s common for the casinos with VIP clubs to offer better cashback percentages to their VIP players.
No Deposit Bonus

No Deposit Bonus

No deposit bonuses are arguably the best promotion offered by online casinos. These bonuses don’t require players to make any deposit. You simply log in and claim your free chip bonus for a straight-up cash reward. The only drawback is these bonuses tend to come with stricter terms and conditions.

Slots Strategy

The outcomes in online slots are always random, but there are plenty of steps you can take to give yourself a highly promising chance at winning. Even the most seasoned of slot players still incorporate some kind of basic strategy into their gameplay to provide themselves with better odds. A solid strategy would include things like only playing slots with a high payout percentage, familiarizing yourself with the bonus rounds, rules of the game, paylines, and different combinations needed to win.

Low Stakes Slots

For players looking to be mindful of their budget can play some of the best online slots for as little as $0.01 at our recommended casinos. If you are setting yourself a limit between $10 and $20 to play within one session, that’s plenty of spins to enjoy for a while before your bankroll needs a little top-up, and you’ll likely hit a feature or bonus once.

Top Casino For Low Stakes:

220% UP TO $12000

High Stakes Slots

For players looking to get a bit more adventurous with their betting amounts, you’ll discover an array of fantastic high volatility slots with betting options ranging from $5 to $150 per spin. These games also contain some of the biggest progressive jackpots, and generally have some of the highest payout percentages compared to other online slot machines.

Top Casino For High Stakes:

200% UP TO $2000

What is Payout Percentage

Payout percentage, or Return to Player (RTP), is defined as the percentage of the total amount of cash that a slot takes from players over a period. Once it hits a certain point, it pays out that percentage in winnings to a player or multiple players depending on the type of game. In most slots, the payout percentage ranges from 75-98%, but this varies on the type of slot, along with the casino. While this can help you build some idea of your expected payout on a game, the payout percentage doesn’t mean you’ll always win back 98% of your winnings for every $100 wagered -- it’s merely what the machine is likely to pay out on average, over time.

The Best Real Money Slot Payouts in 2020

  • Jackpot Jester 99.90%
  • Ocean Princess 99.10%
  • 1429 Uncharted Seas 98.60%
  • Blood Suckers 98%
  • Kings of Chicago 97.80%
  • Caesars Empire 97%
  • Guns’ n’ Roses 96.98%
  • Wheel of Fortune 96.60%
  • Mega Fortune 96.04%

How to Play Online Slots

There is an abundance of different and exciting real money slots to choose from at our online casinos. Whether you’re looking to play slots with multiple paylines, or slots with big bet multipliers and bonus rounds – the style and methods for playing are similar for all types of slots, but you’ll want to understand what these extra functions do and how to use them in order to maximize your chances at winning.


What are Paylines

These are the lines containing symbols players must match up to win. The very first slots only worked with one singular payline; whereas today, online slots can feature hundreds of fixed and variable paylines, which give players multiple chances to hit a winning spin. Slot games usually require you to spin combinations of scatter and wild symbols on a payline in order for the machine to pay out.


What are Scatter Symbols

Scatters are the symbols in online slots that help players unlock winning combinations. These are the key to opening up a portal of prizes and free spins if they trigger a bonus feature. They can also result in smaller jackpot wins and assist in combinations that can trigger a progressive jackpot. Scatter symbols can appear at any given time in the game and cannot be replaced by any other symbols.


What are Wild Symbols

Wilds are another symbol in online slots that are capable of helping players achieve winning combos. These are the symbols that act as a substitute for less desirable symbols in the game, such as the game’s low-paying symbols. Wilds can also unlock free spins and trigger exciting bonus features that give players the chance to earn more cash and prizes.


What are Multipilers

Multipliers can usually be triggered during the bonus rounds in slots games. They activate once the player has matched up a certain winning combination on the reels, which then results in their stakes multiplying by a specific figure. With some slots, this can be as much as 100x the bet per line or the total bet placed. Multipliers are especially profitable when a player bets the maximum coins (BET MAX button).

Slot Machines: Fun Facts

There are many unanswered questions when it comes to slot machines and their non-physical nature. Even now, experts are still wondering what makes them so categorically addictive, where the first one really originated from, and how slots will evolve in line with the technology world over the next few decades. Though these are facts we’re yet to establish, here are some interesting truths behind slot machines that we do know.

Number Icons1

Slots Aren’t Always Called Slots

In the UK, slots are known as “fruities” or fruit machines, while the Scotts refer to them as Puggys, and the Australians refer to them as “pokies”. Some non-English speaking countries are known to have different names for slots as well.

Number Icons2

All Online Slots Are Unique

Though online slots may look similar, no two are the same. Every individual slot features its own custom theme and layout, along with unique symbols, bonus rounds, and jackpot amounts.

Number Icons3

The First Slot Machine

The Liberty Bell is recorded as the first-ever working slot machine. It was developed in 1898 by a mechanic named Charles Fey, and it initially worked with 3 drums and 5 different symbols. When 3 bells appeared, the machine would pay out 50 cents as the top prize.

Number Icons4

The Largest Slot Win

The record for the largest payout on a slot machine went to an LA-based engineer in 2003. The man won $39.7m after wagering $100 on the Excalibur slot game, but due to the sheer size of the jackpot, the winnings had to be paid out in increments of $1.5m a year for 25 years.

Number Icons5

All Slots Are Random

Both online and land-based slot machines all work with Random Number Generators (RNGs) to make sure every result in a game is completely unique. This makes slots impossible to predict or manipulate in any way.

Number Icons6

Two Kinds of Jackpots

There are two types of jackpots available to win in online slots; a progressive jackpot that increases in value as more people play the game, and a fixed jackpot that pays out a maximum set amount.

Number Icons7

Vegas is the Slots Capital

It may not come as much of a surprise, but Las Vegas is the epicenter of slot machine games. There are over 200,000 slots in Vegas alone, which equates to roughly 1 slot machine per 8 people residing in the city.

Number Icons8

The One-Armed Bandit

The notorious slang term “one-armed bandit” was the first expression for the crafty criminals who could rig the outcomes of slot machines to get free money. As time progressed, it eventually became an official term to describe the slot machines themselves.

Meet the Games Makers

Online casinos offer an expansive range of video slot titles, many of which come from a handful of industry-leading software developers. When it comes to video slots, these guys really know their stuff. Here are some of our favorites to look out for.

Online Slots Frequently Asked Questions

Online slots work with the same dynamics as the machines found in land-based casinos. The only difference is: online casino players get more bang for their buck. The concept is the same for spinning the reels and matching symbols to achieve big wins, but online slots provide players with additional bonus rounds, bet multipliers, and free spins. This gives them the opportunity to earn much more compared to land-based casino gaming.

A progressive jackpot is the top prize money in a game that continues to increase over time. As more people play, the game deducts a portion of every bet placed; contributing to the jackpot until it pays out to a winner or multiple winners. Progressive jackpots are increasingly common in today’s online slots. These amounts can get exceptionally high and can trigger at any given moment.

Make sure that you check out the Return to Player (RTP) percentage for the game, as well as any special bonus features within the game itself, the level of volatility, plus the ratings. While some slots pay out more than others, we recommend focusing on playing a slot machine that you enjoy, and which isn’t too demanding on your bankroll.
It’s not possible to play rigged slots if you’ve chosen to play at a reputable online casino. All online gambling sites are strictly regulated to ensure fairness and randomness throughout all their casino games. When it comes to slots, these work with complex Random Number Generators (RNGs) to ensure the outcomes are unique with every spin.

There are no single best-paying online slots, as each game has its own RTP percentage and individual jackpot amounts. It’s always advised to look for a slot with a minimum payout percentage of at least 95%. Anything less than that is more or less a waste of time. Progressive jackpots will give you the biggest wins, with Mega Moolah holding the record for a $21,067,477.68 jackpot, triggered in September 2018.

Many reputable online casinos offer players the ability to play online slots for free. The process is simple and follows the same method as playing with real money games. Find the title that you would like to play; you’ll then find an option to start free play mode or real money mode at the game’s home screen.
For mobile slots, the available currencies will depend on the casino itself, along with your place of residency, as not all banking options are available in all countries. Most online casinos accept USD, AUD, EUR, GBP as the most popular currencies, with some also offering cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and Litecoin (LTC).
The U.S. has a candid history with slots and gambling, with online gaming banned in the USA through the Unlawful Internet Gambling Enforcement Act 2006. All is not lost though, America is slowly releasing the grip on gambling legislation, and many online casinos are providing real money slots to U.S. players.

Several reliable software providers are creating innovative and enjoyable slot games in 2020. Each of the gambling sites we recommend will feature some of the best software providers, including big names like NetEnt, Microgaming, Evolution, Realtime Gaming, Yggdrasil Gaming, Elk Studios, and Playtech.

Yes, winning real money playing online slots is very possible. However, remember that gambling games are random and winning is entirely up to chance. Big wins are still possible, though, and we recommend you focus on playing progressive jackpot slots if winning is your main reason for playing.

Welcome bonuses are provided to players upon signing up to an online casino. Once you’ve created your brand new player account by entering a few personal details, you’ll then receive a unique bonus to redeem at the Cashier and use on all your favorite online slot games.
3-reel slots are great if you want a game that is simplistic and easy to grasp, but they don’t always provide the best payout potential. 5-reel slots, on the other hand, feature multiple ways to win more prizes through exciting bonus rounds, free spins, and the opportunity to multiply your stakes.
