Guide To Finding The Best Online Slot Bonuses

Other times, there is a decent bonus at an operator that has an insane number of slot game options – too many to resist at least trying it out.

Slots bonuses help you enjoy real money online gambling to the fullest. There are many different types of sign up casino bonuses that you might encounter. Below are the most popular ones for slots fans. 

The first offer when you register is a welcome offer of some sort. It’s activated with your first deposit and usually gives you an extra amount of cash to start your first session with. It can also include free spins, which makes it the ultimate online slots bonus, as long as the attached T&Cs are reasonable.

120 free spins used to be the best offers around - but competition has forced operators to raise the bar.

No Deposit Slot Bonus

Another popular bonus to spend in slots is the one you get for free when you register an account, also known as a No deposit bonus. As it’s usually a smaller bonus or spins tied to specific slots, the best way to spend it is on slot machines. Especially games where you can lower you bet amount per spin to stretch it out.

Deposit Bonus for Slots 

Following your first deposit, there are usually a bunch of ongoing offers available through the promotions-tab. This includes but isn’t limited to deposit bonuses like the welcome offer, which adds a certain % to your balance. You can often find cashback bonus casinos that give you back a bit of your losses, slot tournaments where you can get your hands on additional slot bonuses just for playing, much like extra perks offered in various loyalty- or VIP programs.

Which slot bonus is the best for you can depend on several things. Except for the value of the bonus, you want to make sure you can actually play the slots you like with it, and that you can cash out any potential winnings. Here are some things to keep in mind when looking for the best slots bonus:

Bonus Money Vs Free Spins

When picking a casino slots bonus, you can either go for bonus money added to your deposit, or free spins that will activate in a selected slot game (or a combination of both). If you see that the spins are activated in a slot you want to try, I’d say go for it. Otherwise, it would be better to opt for a deposit bonus for the simple reason that you can pick which game you want to play, as well as your bet per spin (within the limits stated in the offer). Free spins always have a set value.

Wagering Requirements & Eligible Slots

Wagering requirements will be attached to whichever offer you opt for, but they can vary a lot. If the number is higher than average, make sure it doesn’t include your deposit amount as well as the bonus money. When choosing free spins, they apply to any winnings. – Either way, check out the list of excluded game titles in the T&Cs of any chosen offer, as there are always slots that don’t contribute to meeting the playthrough requirements.

Possible Payment Hiccups

Not all payment methods activate bonus offers. Common examples are Skrill & Neteller at many sites. Some slots bonuses also come with a withdrawal cap, meaning you can’t cash out more than a set amount even if you were to win bigger with a bonus. Though this usually applies to freebies, make sure you know what to expect before you deposit and start playing.

Avoid disappointment by scrolling through the fine print for the max bet allowed and any time limits attached to the offer before you start playing.

Here’s one of the most discussed topics among gamblers. Bonus wagering requirements are the rules that define how a bonus works. And these rules are not always in your favor. The truth is that bonus money is given away by casino sites to encourage you to play at their site. Although at first glance it may look like the extra money you get is free, this is not entirely correct. Before you can cash out any winnings derived from your bonus, you’ll be required to meet a set of predefined wagering conditions.

Different types of slots bonuses can have different terms and conditions attached to them, so it’s crucial that you know what to expect once it’s time to cash out. A wagering requirement means that you must play the bonus amount a certain number of times before any remaining money is converted into cash.

When you claim a Welcome Bonus and agree to the terms and conditions, you’re agreeing to wager the bonus money (or in some cases, the bonus money plus your deposit) a number of times, usually between 30 and 40 times within a maximum number of days, before you can withdraw any remaining winnings. For example, if you deposit $20 and unlock an extra $20 that have a wagering requirement of 30 times that must be completed within 60 days, this means that you must wager $600 within 2 months, otherwise your bonus funds and any winnings generated from the offer will be removed from your account.

Another thing to look out for are game contributions towards the wagering requirements, so that you’ll know which games to play and which to avoid. While slots generally contribute 100% to the wagering requirements (meaning that every $1 you play counts as $1 towards the wagering), some other casino games only contribute 20% or less. The lower the percentage, the longer it will take you to fulfil the wagering requirements.

We encourage you to compare the wagering requirements of different slot bonuses before you decide to grab a bonus offer.

US online casinos make this process as smooth as possible, ensuring you can lay your hands on a slot bonus in as few steps as possible. This usually involves a series of actions that start with you opening an account at any of the established or new online casinos in the USA. Let's take you through it step by step:

Step 1 - Select a top casino

Your first move is to select a great online casino. Check recommendations at Casinos.com to explore sites that not only offer the best slots bonuses but where you’ll also be able to play the best real money online slots, while benefitting from fast and secure payments.

Step 2 - Open a new account

Registration is an easy process. You will need to supply your home address, phone number, email address and a few other details, depending on the State regulations. The Federal Government takes identity verification seriously, but it’s all for your own safety.

Step 3 - Claim your slots welcome bonus

On the majority of slots sites, you just need to opt in to the welcome bonus to claim it, while at other online casinos you may need to enter a special casino promo code to activate a new customer bonus. Either way, you’ll be guided on how to grab your welcome offer.

Step 4 - Make the first deposit

Your first deposit is the key that unlocks the Welcome Bonus. Adding funds to your account is another smooth process that many online casinos get right. Make sure you use trusted, reliable, and fast payment methods, like Play+ or PayPal. 

Step 5 - Hit the reels and start playing

You've registered, claimed your online casino bonus, and made your 1st deposit; now it's time to start playing. Head to the lobby and look for the slots you would like to play. If you don’t have a favorite, many slots sites will offer you their recommendations on the top rated and hottest slots. Good luck!
