What is a slots bonus?

When a slot site offers a bonus, this is like money that can only be used on the site. The idea is that you can make your deposit stretch a little longer by playing with bonus as well as your own money.

Bonus money can’t be withdrawn, but if you play with it and meet the wagering requirement, you’ll be able to convert it to real cash, which you can choose to withdraw.

Not all players like to take bonuses, but for other players, good bonus offers are a must when choosing a site.

Which sites offer slots bonuses?

Most sites offer a bonus of some kind, and many of them offer slots bonuses.

  • Often, sites offering both bingo and slot games will offer more bingo bonus than slots bonus
  • Slot-only sites won’t offer any bingo bonus
  • Some sites are cash-only (sometimes called no wagering) and these do not ever offer bonus money
  • Some sites will let you use slots bonus on both slot games and casino games, others will not
  • Look out for both welcome bonuses and bonuses for current players

Check the Promotions section of BingoPort’s reviews to see what kind of offers your chosen site tends to run. This will give you a rough idea if they are more focussed on bingo, slots, or casino.

Why is a slots bonus good?

Slots bonuses can be like gold dust, but why do players love them so much?

  • You can play without dipping into your own deposit money
  • Play for longer before depositing again
  • Try a game you aren’t sure if you’ll like without wasting your own money

Many players choose a slots site to play on based on its welcome bonus and the deposit offers the site gives once they are a member.

What should I consider when taking a slots bonus?

Although slot bonuses can be super fun, you should always read T&Cs before claiming any offer, to make sure it’s right for you. Here are some things to bear in mind when considering a slot bonus offer:

  • The winnings from a slot bonus will likely be in bonus too, and must be wagered before you can withdraw them
  • Winnings from a bonus may be capped at a maximum amount
  • Withdrawing before you have completed your wagering requirement will mean that you lose your bonus and any winnings gained from it

What is a wagering requirement?

A wagering requirement will come attached to a bonus. It is the amount that you must bet in order for your bonus (and any winnings from it) to turn into cash you can withdraw.

It is usually a multiple of the bonus amount, for example 5x, 25x, or 60x, and can be found in the T&Cs of any offer you see.

If you took a £10 bonus with a 5x wager requirement, you would need to wager (or bet) £50, and then your remaining bonus and winnings would convert into cash.

Can I win cash from slots bonus?

It is possible to win cash from a slots bonus:

  • Meet the wagering requirement on the bonus
  • Any remaining bonus and winnings will convert to cash
  • This can be played or withdrawn as you choose

As with all gambling, whether or not you are able to win cash from your bonus will be a game of luck, but it does happen.

Can I get a slots bonus for free?

Most slots bonuses you will see are deposit bonuses. That means, you deposit, and the site will give you some bonus as a treat on top of your deposit.

No-deposit bonuses do exist, though they are rare. For these, you won’t need to deposit a penny to claim the bonus, although it is likely to just be a one-time offer for new players. Keep an eye out for regular bonus code promotions on slots sites.

Is a free slot bonus the same as a no deposit slots bonus?

For a no deposit slots bonus, you don’t have to deposit a penny of your own money to get the bonus. ‘Free bonus’ is a little more complicated.

The word ‘free’ might not necessarily mean that you don’t have to deposit, so make sure to check the offer carefully.

Think about it, when you get a free gift in a shop, it’s usually with a qualifying purchase. The bonus is still free- you’re not buying it- but to get it, you need to make a deposit. You end up with your deposit and the bonus both.

What is a free spin?

Rather than a bonus, you may be offered some free spins as part of a deposit offer. These work a lot like bonus, except they will be for a specific slot game only. You’ll get some spins on that slot, and whatever you win is yours.

It’s worth noting that there may be restrictions on this. Free spins may have a win cap, so you can’t win more than this amount on your free spins. They may also have wagering requirements attached to their winnings.

Do free spins pay out in slots bonus?

Free spins often do pay out in slots bonus, but sometimes, you’ll find they pay out in cash.

Most free spins will have a win cap, which is the maximum amount you can win on the free spins, and many will have a wagering requirement. This means anything you win on the spins will be in bonus that must be wagered.

However, free spins are very common on cash-only sites, where winnings will be in cash with no wagering requirements.
