How can you benefit from an Online Slot Bonus?

To top it up, you can choose from any Classic, Video, 3D or Progressive Slots and grab your sweet Bonus treats to enjoy your favorite Slots even more!

Since Slots are the most popular casino games, many online casinos go out of their way to lure players from all over the world with a scrumptious package of Casino Slot Games with Bonuses.

When you go through various casino offers, you will normally find either a number of Free Spins plus an amount of Bonus Cash allowance or a number of standalone Bonus Spins that are linked to your First Deposit Bonuses.

Here are some common Slot Bonuses you should go for when you play Slots online:

  • Deposit Bonus – this Bonus is based on the amount of money you deposit every time you play. The highest percentage is 100%. In other words, every $10-dollar deposit is doubled, and you get to spend $20 instead while spinning your favorite reels.
  • No Deposit Bonus – this is a spicy cash offer that gets credited straight into your player account; in some cases, you are not even required to make a real money deposit!
  • Reload Bonus – this works exactly like the First Deposit Bonus, but it’s offered to existing players.
  • Free Spins – the most dazzling Casino Bonus offered to new and existing players. With this free offer, you get more spins than you actually pay for!

TIP: Keep in mind that these awesome freebies can land a mighty real money jackpot! Be wise and collect all your freebies before spending real cash.

As a new player, you are entitled to great online offers that will help you increase your bankroll from the very first day.

You can choose from a vast range of Online Slots that cater to your gambling appetite and gaming preferences. Go for the Classic 3-Reel Slots if you have that nostalgic feeling that is sending goosebumps down your spine when you see those gentle one-armed bandits and colorful fruity symbols. These are lower variance Slots, which means that your cash flow will not fluctuate much throughout the games.

Modern Video, 3D and Progressive Slots are typically 5-Reel Slots that offer higher variance and some other exciting features like skyrocketing Bonus Rounds and fascinating Free Spins.

Take a note:

Do you know the difference between cashable and none-cashable Slots Bonuses? Here is a basic overview of the key differences:

  • Cashable: meet the wagering requirements and keep them.
  • Non-cashable: bonuses cannot be kept but wager your Sticky Bonus and pocket the winnings.

Do all casinos offer Bonus Slot Machines?

If you are looking for freebies, then head straight to a reputable online casino and check what wagering requirements apply to the offer you wish to use. Also, be sure to go through the T&C page carefully to ensure you understand how the Bonus Scheme works.

As a rule of thumb, it’s a good idea to choose a casino that offers high Return-to-Player or, also known as, RTP rates. They typically range between 93 and 98%.

Land-based casinos do not offer any Free Bonuses and you would need to spend your own cash to make any bets. When you play online and choose Slots with Bonus freebies, you get access to world-class casino entertainment that will not cost an arm and a leg!

Good to know!

Don’t be surprised when you find some Slot Games with Bonus rates that range between 300% and 500% of the initial deposit - these are totally legitimate offers that are available exclusively on the reels of various Online Slots. Some casinos require customers to use a Bonus Code that will apply to specific Casino Slots so that you can claim your Free Bonus Spins.
