What Is A Bonus On Slots?

A slots bonus is a casino bonus that you can use on online slots . However, this is not limited to the casino bonuses that are especially for slots, but covers all big bonuses that can be used on slots . These are almost all of them. It occasionally happens that a casino has a special promotion with a bonus that is only valid in the live casino , for example. But if this is the case, then it is very clearly marked.

Most Popular Slots with Bonus

We have already indicated that there are various bonuses for those who like to play slots and we would like to explain the most common bonuses for you. These bonuses can be divided into two categories; namely specific slots bonus and general casino deposit bonus . Of course, specific slots bonus means that the bonus is especially for slots and the general bonus can also be used on other games.

Free Bonus

  • No Deposit Bonus : Despite the fact that you may come across the no deposit bonus as a small credit, we still see it as a specific online slots bonus. This is because you almost always receive a number of free spins as no deposit. An advantage of this bonus is that you do not have to pay for it, but you can win real money with it. All you have to do to win such a slots bonus is to create an online casino account.
  • Free Spins : This is a very common slots bonus. This is often already part of a welcome package and otherwise you can expect a number of free spins after your welcome. This also makes players very happy; even though each set of free spins is only available on one slot, it offers them the chance to play one of the favorites or discover a new slot .

General Bonuses

Pros and cons


  • You know for sure that you can play slots with a slot bonus.
  • The online slots bonus offers the chance to try new slots free of charge.
  • There is always a chance that you will win a nice cash prize.
  • The online casino that offers slots bonus is appreciated by the lovers of these casino games .
  • You will often find the very latest slots in a slots with bonus casino.


  • If you go for the online slots bonus, you cannot play other casino games with it.

Terms of Bonuses

Of course there are conditions to the bonus slots. The most famous of these will be the wagering requirement. This means that you have to wager the amount of the registration bonus and the winnings a number of times. Normally this condition is related to the size of the bonus. This means that you have to wager the amount more often and get more time for this if the bonus is larger.

But before you accept the slots bonus, there is also an important condition that you must take into account. This is the fact that you have to activate the sign up bonus within 30 days because it expires otherwise. If this happens, you will really lose the bonus. Another condition that you should be aware of is that some casinos have a maximum profit per bonus.

This means that no matter how much you have left after clearing the bonus, you can only withdraw the maximum amount indicated. Not all casinos have these rules, so be sure to check. We think that you now know the most important slots bonus conditions, you can always contact the casino for more.

RTP And Variance

If you can choose which slot machine you will play on with your online slots bonus, we advise you to go for the games with the highest RTP. This is the opposite of the house edge and shows the portion of all bets that goes back to the players. A logical conclusion is therefore that with a higher RTP more money is paid out to the players and your chances of winning are therefore higher.

Another thing that also has to do with online casino odds is the variance. If you play on a slot with a low variance, you have a better chance of winning, but the prizes are usually lower. The opposite is true for slots with a high RTP variance . So if you want to go for the jackpot , it is wise to choose a slot machine with a low variance. In case you really want to have the utmost control over your bonus slots, go for the slot with the highest hit frequency. This is also a percentage and indicates how many of the possible combinations yield a win.

Tips for bonuses

  • Before you choose one of the slots with bonus, first determine your goal and choose accordingly.
  • Be careful with your online slots bonus, if it doesn't work, stop for a while and don't use up the bonus in one go.
  • Before you start unlocking, check carefully which casino games really count towards this to avoid disappointment.
  • If things don't go well, you can also choose to play on a slot with a lower variance; so you may be able to extend your playing time.
  • With a slots bonus you usually cannot play jackpot games.
