What is an online casino free spins bonus

Online casinos offer a variety of bonuses such as first deposit bonuses and no deposit bonuses. The free spins bonus is one of the bonuses available in video slots.

In this article, we will introduce you to the free spins bonuses offered by numerous online casinos. Free spins bonuses also have some caveats, so read this article to make sure you understand them.

Online casino free spins bonus overview

A free spins bonus is a bonus that allows you to spin for free on video slots designated by online casinos.

The number of free spins you can spin depends on the bonus, but most of them are set between 10 and 200 spins. With the free spins bonus you can play video slots just like you would with regular real money.

The free spins bonus does not mean that some video slot features are not available. Many players have won big payouts with free spins bonuses in the past.

Features of the Free Spins Bonus

Here are the features of the free spins bonus features.

Specified available video slots

Just because you received a free spins bonus doesn't mean it's available on all video slots.

Free spins bonuses are available on a limited number of video slots and are usually only available on 1-3 video slots.

Video slots with free spins bonuses are set by each online casino's popular video slots and latest video slots.

Also available on mobile

The free spins bonus can be used not only on your computer, but also when playing the eligible video slots on your mobile device. There is no difference between desktop and mobile when it comes to handling free spins bonuses.

However, not all free spins bonus video slots are mobile compatible. In this case, the free spins bonus can only be used on a computer.

you can play video slots for free

Free spins bonuses allow you to play video slots without spending real money.

So, for example, when you register at a new online casino, you can play video slots for free to find out what kind of games they are.

You can also take advantage of the free spins bonus and aim for cash prizes. However, when you win a free spins bonus, such as a welcome bonus, you may want to use the free spins bonus as a practice exercise to learn how video slots work, rather than for winnings.

Sometimes there are no withdrawal conditions

Most online casino bonuses have wagering requirements. However, in rare cases, free spins bonuses have no wagering requirements. In this case, you can withdraw your winnings from the free spins bonus immediately.

When to get the free spins bonus

Here are the times when you can claim the free spins bonus:

Registration bonus (no deposit bonus)

When you open a new account at an online casino, you can get a registration bonus as one of the welcome bonuses.

You can get this registration bonus without opening an account and making a deposit. Registration bonuses may award bonus money or free spins bonuses or both.

This registration bonus is automatically granted when you open an account. Alternatively, a bonus code may be required.

First Deposit Bonus

One of the welcome bonuses at online casinos is the first deposit bonus in addition to the registration bonus. This first deposit bonus is a bonus that you get when you make a deposit after opening a new account.

As with registration bonuses, bonus money or free spins bonuses or both may be awarded.

This first deposit bonus can be obtained by claiming the bonus when making the first deposit after opening an account. On the deposit procedure screen, there is an item "Apply for a bonus", so be sure to check it there.


Some online casinos have promotions depending on the day of the week. Such promotions give you unconditional free spins bonuses and bonus money.

These promotions can be found on each online casino site's "Promotions" page. You may also receive promotional offers by e-mail.

You can get free spins bonuses and more by activating the bonus from the promotion page or the invitation email you received.

Also, when new video slots are introduced in online casinos, free spins bonuses are sometimes granted unconditionally to registered users for promotional purposes.


Some online casinos regularly host events and tournaments. Top finishers in these events and tournaments may award free spins bonuses as prizes.

deposit bonus

Online casinos offer deposit bonuses not only to new users, but also to existing users. A deposit bonus, as the name suggests, is a bonus that you get when you make a deposit.

These deposit bonuses are often offered for a limited time and have a minimum deposit amount. And by fulfilling the conditions, you can get the free spins bonus.

Free spins bonus wagering requirements

The free spins bonus has wagering requirements just like any other bonus.

The free spins bonus has a wagering requirement that you have to play x times the free spins you got with the bonus.

For example, get 10 free spins with the free spins bonus. And let's say that the withdrawal condition is set at 30x. In this case, you will have to spin 10 times x 30 times = 300 times to withdraw your winnings from the free spins bonus.

Also, instead of setting the number of spins as a wagering requirement, they may set a wagering requirement on the winnings earned from the free spins bonus. In this case, you have to bet x times the winnings from the free spins bonus.

Let's say you win 5000 Yen with the free spins bonus. And let's say you have a 30x wagering requirement. In this case, 5000 yen x 30 times = 150,000 yen must be used for casino games.

Please note that if you make a withdrawal request before this wagering requirement is met, the free spins bonus and all winnings from the free spins bonus may be forfeited.

Be sure to check the terms and conditions of the online casino, as the terms and conditions for bonus withdrawals vary from one online casino to another.

Free Spins Bonus Notes

Here are some things to keep in mind regarding free spins bonuses. These caveats are listed in our Terms of Use, but it's easy to miss them. So be sure to check the notes here carefully.

Beware of exclusion games

Sometimes winnings must be used in casino games in order to meet the wagering requirements of the free spins bonus.

At that time, you have to be careful about exclusion games. Some online casinos have set games where you cannot use the winnings from the free spins bonus. Generally, live casino games are often set as excluded games.

Using bonus money on this excluded game is against the rules and may result in the forfeiture of all bonus money and free spins.

Conversion rate for withdrawal conditions

Let's say you have to spend $300 to meet the free spins bonus wagering requirements. In this case, 100% of the amount used in all games will not be subject to withdrawal conditions.

Depending on the type of game, the rate of withdrawal conditions is set, and it ranges from 0% to 100%. For example, let's say the poker fill rate was 50%. And let's say you spend $100 in poker. In this case, only half of $100, or $50, can be used as a withdrawal requirement.

If you play only games with a low digestion rate, you will not be able to meet the withdrawal conditions. Therefore, in order to quickly meet the withdrawal conditions, it is necessary to concentrate on betting on games with a high consumption rate. Video slots are generally recommended as they often have a 100% fill rate.

Excluded games and withdrawal requirements vary depending on the online casino. Please be sure to check the terms of use.
