What Are Bonus Spins?

Bonus or extra spins are awarded to players as part of a casino promotion to give players the chance to spin the reels of some of the best slot games.

Why do online casinos offer bonus spins?

For starters, online casinos are trying to convince players to try some the slot games they have stocked in their depository because once they’re in, players will feel more inclined to stick with their casino.

Bonus or extra spins are highly sought after by slot enthusiasts because they get to spin the reels on the house but although you’ll of course keep what you win, one should note that bonus spins come with wagering requirements and any winnings made from bonus spins will need to be played a couple of times over before a withdrawal can be made.

Is there a catch?

Keep in mind that the wagering requirements are not ‘the catch’ in bonus spins offers and they’re set because of the fact that if all players would strike gold when spinning the reels for free, online casinos won’t be operational for much longer. For instance, if an online casino is offering 100 bonus or extra spins as part of their welcome offer and 1000 players make €100 from them, it would send the online casino back €100,000, deeming the bonus spins offer unsustainable. So for this reason, wagering requirements are put in place to ensure everyone gets a piece of the pie.

Pros and Cons


  • Opportunity to play online slots for free
  • You’ll keep what you win
  • Awarded for simply making a deposit
  • Usually come in high numbers when part of a welcome bonus
  • Potential to play for long periods of times for free
  • Profits can be withdrawn after wagering requirements are met


  • Usually limited to a few games
  • Bonus Spins are of a low value
  • Bonus spins offers come with wagering requirements

Don’t let the wagering requirements discourage you from claiming bonus spins offers. Yes, the value of each spin is low, but with lady luck on your side, you can make some big wins which can quickly meet the wagering requirements and transform bonus money in real money, which qualifies for a withdrawal.

No Deposit Bonus Spins

Without a shadow of a doubt, no deposit bonus spins are what every casino player is after and considered as a real treat when choosing the join an online casino.

No deposit bonus spins are usually awarded as soon as the registration process is completed but since no deposit is necessary for the spins to be claimed, they usually come in smaller numbers. If you’re familiar with slots, you’re aware that the value of each spin varies, ranging from a couple of cents per spin up to the hundreds. No deposit bonus spins’ value is on the lower end of the spectrum and usually have capped winnings, meaning that there is a limited amount of winnings that can be claimed.

How to claim winnings from no deposit bonus spins?

All the information about the no deposit bonus spins offer is listed in the terms and conditions and will always include the number of bonus spins awarded, the time frame of when they should be used, the value of each spin, the wagering requirements and the maximum amount of winnings that are eligible from the no deposit bonus spins offer. Once these terms have been honoured players can head over to the casino’s banking section and claim their winnings.

Are there wagering requirements on no deposit bonus spins?

These days, many online casinos are offering no deposit bonus spins offer without wagering requirements, which means that all proceeds from spinning the reels are yours to keep. This is the pinnacle of no deposit bonus spins offers and if you ever come across such a promotion, don’t hesitate to claim it. You literally have nothing to lose and any profits that are made from the bonus spins can be used on any game since it will be all real money.

Slots With The Highest Number Of Extra Spins

Another way to claim extra spins is by playing online slots, with many game providers including bonus rounds which reward extra spins to make the games more appealing and these days, many players are looking for games with the highest number of bonus spins before choosing to play a particular game.


Jumanji is one of the best slots ever released by NetEnt and it comes as no surprise that the number of extra spins awarded in this slot is massive. Jumanji is full of special symbols and bonus rounds which can trigger the free spins, which include ‘vine extra spins’, ‘monsoon extra spins’, ‘monkey extra spins’ and ‘stampede extra spins’. The best part of the bonus rounds is that each bonus round can trigger even more extra spins.

Mega Moolah

Mega Moolah is widely known for its huge jackpot prizes but one element which is overlooked is the random extra spins feature which requires no bonus round to trigger the extra spins. The free spins round comes in batches of 15 and once again, each extra spin can trigger more extra spins, making the game incredibly appealing to slot enthusiasts.

Super Bonus Spins

These type of bonus spins are very hard to come by and it’s very rare to find online casinos offering super spins as part of a casino promotion due to the fact that the value of these spins is usually worth €1 or more. Usually aimed at high rollers, super bonus spins make winning combinations sweeter, since their value is on the upper end of the scale, however, just like any other bonus spins, they do have wagering requirements and more often than not, capped winnings too.

Wagering Requirements For Bonus Spins

Almost all UK casino bonuses come with wagering requirements, which essentially means that for the bonus funds to be withdrawn, they need to be played over a number of times. If the total winnings from bonus spin amount to £5 with wagering requirements of 30, you’ll need to make £150 for the funds to become available for withdrawal.

Bonus Spins Earned Through Competitions

From time to time, online casinos run competitions for extravagant prizes and the runners up are usually awarded a huge number of bonus spins for coming up short of the big prize. These type of bonus spins are aimed at existing casino players and usually have lower wagering requirements. This is because of the fact that these type of bonus spins are for players who would have already spent a significant amount to participate in the competition and having high wagering requirements would defeat the purpose of rewarding players for failing to win the big prize.

Extra Spins By Game Provider

When an online casino has a high number of games available to play from a particular game provider, they choose to have extra spins by the game provider in question because they get a better deal, which is then relayed to new players as part of the welcome bonus. In these cases, the number of extra spins will be higher and the selection of games to use the extra spins on will be far greater, making the welcome bonus, in general, more appealing.
