One thing to look for as you play free slot machine games online is the RTP of those titles. Online casinos will use independent companies to routinely audit games for fairness, and the RTP is confirmed during these audits. When comparing free slots, watch for those that have the highest RTP. This will indicate you have better chances of winning over time. Most online slot games have an RTP of between 93% and 97%. Choosing those with a higher percentage means you will have more payouts when you place real money wagers.

Online Slots vs. Free Slots Machines?

You will find a massive collection of slot games when you access any online casino. These games make up the most considerable portion of any gaming portfolio. You will find that most of the games can be played for free and provide a way to preview different titles. The difference between playing free games and playing for free using bonus funds is winning money. Playing with bonuses or using deposited funds will allow you to collect payouts. No payouts will be awarded if you preview slots in a free play demo mode. Free slots can only be played at online casinos. If you visit a land casino, be prepared to place wagers on these games.

Free Online Slot Bonuses and Features

As a slot player, you will find many added ways to collect payouts. Many of the online video slots will come with exciting bonus features that can boost overall payouts. You will also find great casino bonuses that can award free spins and free cash, so you have more ways to wager and benefit from in-game bonus features. Want to learn more about these special features? We have the details right here!

Wild symbols

Wild symbols are common with online slots, and you will find these on classic games and video slots. When a wild appears, it takes the place of standard game icons to help you create more winning combinations. Some wilds will also be multipliers, so you can enjoy larger returns when these are used. Based on the game, wilds may not substitute for scatters or bonus symbols on the reels.

Free spins

Free spins are the most popular feature found with the latest and greatest video slots. You must get specific icons on the reels to trigger a free spins bonus round. When this happens, you are awarded a number of spins that will be played with no additional cost. These bonuses offer great payouts and are often the main attraction for players when comparing different game titles.

No deposit slots

No deposit bonus slots are great options for new players who are just getting started with online gambling. These bonuses are provided to new players who create a new member account. You must register to become a member, and the casino will credit the no deposit bonus to the account. This can be money or free spins and can be used to play some of the most popular slot games.

Slots no wagering

One of the best ways to play slots online and benefit from payouts is to find wager-free slot bonuses. Slots no wagering offers will allow you to play using provided bonus funds, but you will not have to wager additional money to clear any wagering requirements. This means you can keep everything you win when playing games!

Wheel spin bonuses

A wheel spin bonus can be an in-game feature or a casino bonus. If it is triggered during a game, you will spin a wheel to receive a cash payout, multipliers, or free spins. If the casino offers a wheel bonus, players can spin the wheel when making a qualifying deposit to earn a match bonus or free spins.

Pick style bonuses

Pick style bonuses are a form of a second screen bonus, and they are offered with many of the newer video slots. You will have to get triggering icons to start the bonus and select icons displayed on the screen. These can offer multipliers, free spins, or an instant cash payout.

Hold and spin bonuses

A hold and spin bonus is a feature offered with newer slot games. This is also referred to as a respin feature. When this happens, specific icons will be frozen in place on the reels as the remaining reels spin again. This provides players with an extra chance to create winning combinations. Most of these features will continue for multiple spins, so there are great chances to earn returns.

Promotions & Competitions

Each online casino will have different offers for registered members. You will find ongoing bonus deals that can be used to play more of the supported slot games, and some competitions can be entered. With many great promos provided, slot fans always have ways to increase their chances of being a winner.

Loyalty rewards

The best casinos in the US will have a loyalty program in place, so as you place wagers, you will earn points. These points can be redeemed for casino cash or exclusive bonus deals. Most programs have tiers, and each level will provide added benefits, such as cashback deals, weekly free spins, or special match bonuses.

Scatter Symbol

A scatter symbol is a common icon used with many video slot games, and when you get multiple scatters, you can win an instant payout. These icons are also used to trigger the main bonus features in the game.


Slot games that feature multipliers are the best choices. Multipliers can be wild symbols that can double or triple payouts, or you can receive a multiplier in a free spin bonus round. Any game that uses a multiplier will provide more payouts and offer players a better chance of earning maximum returns on wagers.

Free Credits

US online casinos often provide bonuses that award free credits to attract players and keep them coming back for more slot action. These can be deposit or no deposit bonuses, and the credits earned can be used to place wagers on some of the most popular slot games for the chance to generate real money payouts.

Terms & Conditions of Free Online Slot Bonuses

Free slot bonuses at casino sites will always have terms and conditions. When you redeem a bonus, you must meet all terms. These will include wagering requirements, the maximum bonus amount, a max payout amount, and any restrictions on games that can be played or how much players can bet using bonus funds or spins. Always check the terms before redeeming a bonus and check the expiry date since some free slot offers are only valid for a short time.


In addition to checking the RTP of a slot game, always check the volatility. The RTP assesses the risk involved when playing. It will let you know how often you will win or how large or small payouts will be. Games with low volatility will offer frequent payouts, but the amounts will be low. High volatility games pay out less often but for higher stakes.
