Slot Bonuses FAQ

What is a Slots Bonus?

Online slot players enjoy the best bonus deals at online casinos. This type of bonus requires that you play only online slots which count 100% towards the wagering requirement, and it makes it much easier to wager.

Where can I find the best Slots Bonuses?

At CasinoWow you can find the hottest and latest slot bonuses. For the best online casino experience with this type of bonus head over to Bitstarz Casino today!

Are Slots Bonuses only offering free spins?

No, though free spins are popular and very often included with most slot bonuses there are other forms that can be found. Deposit match percentage, cashback and free play bonus on a particular slot or set of slots.

Types of Slots Casino Bonuses

Slots bonuses don’t just come in one select package but can actually be offered in several different forms. These include:

1. Deposit Match Bonuses

Here, you will be required to make a minimum deposit before the casino adds the bonus to your account. The casino will often match a percentage of your deposit up to a specific limit. For example, you may find a deposit match bonus in the following form: 100% up to €400 VIP Slots Bonus. Here the casino promises to match any deposit you make up to the amount of €400. So, if you opt to deposit €300, the casino will apply an extra €300 to your account, giving you €600 to play with. Be aware that in most cases you will have to wager the amount several times before you can withdraw wins from the casino.

2. No Deposit Free Spins

The No Deposit Free Spins bonus allows you to collect a set number of free spins on one or more specified slots after you have created a player account. No deposit is required but any wins made off of these spins will carry a withdrawal limit in most cases.

3. Combined Match Deposit Bonus + Free Spins

This is a common form of a first-time welcome package bonus, which offers you a specific percentage of your first deposit as a match with added free spins to boot. This certainly gives you an advantage at the casino, but wagering requirements are usually high.

4. No Deposit Bonus

As stated in the name, this type of free money bonus is awarded without the need to make a deposit. You are usually offered an amount of cash for merely registering a profile at the casino. The wagering requirements on such bonuses are a bit higher than on other match deposit bonuses, and the withdrawal amounts come with strict limits.

5. Payment Method Casino Bonuses

There are always new payment methods being adopted by online casinos. Often, casinos will offer special exclusive bonuses to players who choose to make use of specified payment methods. This can come in the form of any of the above-mentioned casino bonuses.

Slots Bonus Wagering Requirements

All bonuses come with wagering requirements or playthrough procedures of some kind. A wagering requirement is the number of times that the casino bonus must be wagered before you can draw on any wins.

If the casino stipulated the wagering requirement of 20, it means that you must wager 20 times the bonus amount before you can claim any wins.

As an example:

A deposit match of 100% on a €200 deposit is €200. With a wagering requirement of 20 (20 x €200), you will have to wager an amount of at least €4,000 before drawing on any wins. Some casinos may even require you to wager the combined deposit total (€400 x 20 = €8,000). For this reason, we implore you to familiarise yourself with all the terms and conditions for bonuses at an online casino, before claiming any promotions.
