How first deposit bonuses work at UK casinos

We don’t pull punches at Slotsquad. Too many slot review sites say that deposit bonuses are incredible, amazing and “incredibly amazing”. Do you want us to say that too? Or would you rather we told you how casino deposit bonuses work, and more importantly, why they work.

If a player deposits £100, they play with £200! But remember, £100 is bonus money subject to wagering requirements!

There is nothing free in this world, and that couldn’t be truer than with online casinos.

The Welcome Bonus

The welcome bonus is an important stage of your online casino membership. It’s the first impression that players have of the brand, and also the first hurdle they take when trying to withdraw any future winnings. We’re talking about the first deposit bonus, the multiple deposit bonuses and any other bonus associated with joining an online casino.

So how do casino deposit bonuses work? They work by offering an incentive in return for action, normally adding bonus funds to the players account on their first deposit. The first deposit bonus at 100% match is the industries standard and most popular. If you deposit £20, you get £40, with £20 subject to wagering requirements.

Deposit bonuses come in many forms, but some are like the Devil himself. Charming, seductive and completely evil. At Slotsquad, we avoid these like the plague. But whether you’re getting £100 free, 20 free spins no deposit, five deposit bonuses, 300% match, deposit £10 get £60, etc. They all carry wagering requirements.

The Wagering Requirements

What are wagering requirements and why do deposit bonuses have them? If you go up a couple of paragraphs, I wrote nothing is free in this world, remember. Here is the reason things are not free in online casinos, bonuses are not really free. Because bonuses are subject to wagering requirements. The withdrawal hurdle that lies buried within the terms and conditions.

The terms are conditions for any online casino are boring, they’re cleverly small, tactically spaced and difficult to read. Strange when you about it, as the terms and conditions contain the casino’s most important stuff. Still, who reads the terms and conditions anyway? Someone who wants to know if they’ll ever get their casino winnings perhaps?

So how do deposit bonus wagering requirements work? Example: If you deposit £40 and play with £80 (using a standard 100% deposit match bonus), £40 of that £80 (the bonus) will need to be wagered a number of times. Wagering amounts vary from 5 x your bonus up to 50 x your bonus, perhaps more. But we’ll use 35 x wagering in our example.

Still with me? So if you deposit £40 and get £40 free, you’ll have to wager that bonus 35 x before you can withdraw any winnings associated with that bonus. You would have to wager through £1400 of slots and casino games. But wait, not all casino games are equal when it comes to wagering.

Not all slots and casino game wagering is equal

In our casino deposit bonus example above, you’ll have to wager through £1400 (your £40 bonus at 35 x wagering) before you can win to your wallet so to speak! That means withdraw winnings to your bank account. So how do you wager through that £1400 and which games do it more quickly? It’s important to note that not all games contribute to your wager equally. In fact, some are worse than others.

To get the information for you, I’m wading waste deep in the terms and conditions. It’s painfully boring, my eyes are squinting, and it hurts trying to understand, but I need to read on. It’s in here where we find out which slots or casino games contribute best to bonus wagering amounts.

In the UK slots site that we looked at, slot games contributed to 100% of the wagering amount, whilst classic slots contributed 75%. On the other hand, live dealer games such as Roulette and Blackjack offered just 5% towards the wagering of that bonus. Top tip, play online slots whilst you still have deposit bonus money. You’ll work through that wager much quicker. But check the terms and conditions of the online casino you intend to deposit with first.

Why casino first deposit bonuses work

Look at this logically, we said in our example that if you deposit £40, you play with £40. But to withdraw winnings you must play through £40 35 times, that’s £1400. It’s not a simple or quick process to do, nor is it meant to be. It’s why casino first deposit bonuses work, to keep us playing.

We get excited, play longer, get into games and find slots that we like playing. We see jackpots and winner leaderboards; winners, and we see potential wins for ourselves. All whilst trying to wager through £1400 of that £40 deposit bonus money.

That’s why deposit bonuses work? It’s not entirely in our interest, but here’s the good news. Once the bonus wagering amounts are met, we’re in a position to get on with business. Actually winning when we do win.

The best way to approach casino and slot bonuses

UK slot bonuses and casino deposit bonuses might offer the earth, but players should look more closely. See any bonus as a free look at the slots site or brand, a free demo if you like. Too many people get upset and misled by welcome bonuses because they jump without looking down first. Often left wondering why they can’t withdraw their winnings from the bonus money.

At Slotsquad, we’re not against welcome bonuses of any kind. We just want players to understand them. After all, the real fun starts when the welcome bonus and any wagering requirements are gone.
