What is a Casino Bonus?

In the increasingly competitive world of online casinos, each operator will want to stand out from the others by offering a bonus or promotion a potential player can’t ignore. When a casino bonus is offered, the player is given something extra in return for carrying out an action such as signing up, making a deposit, being active regularly or spending a certain amount of money.

They can be part of a welcome package, come in the form of spendable points, be offered as competitions or regular incentives or be included as part of a VIP club, encouraging people to use the casino more often in order to be allowed access to additional perks.

Welcome Bonus

A welcome bonus allows the player to develop a positive relationship with the online casino from the beginning, as they are rewarded simply for signing up, and in some cases just for making their first deposit, which is often only required to be a small amount. Often, welcome bonuses come in the form of a sum of virtual money, designed for use on casino games, which matches the deposit amount.

So if a player receives a welcome bonus of a 100% match and deposits £10, they will have £20 in total in their virtual wallet – £10 of their real cash and £10 of virtual casino money designed to encourage the player to stay active on the site for longer by playing more games.

No Deposit Bonus

These types of bonuses can either be provided to new players, as an incentive to keep them playing on the site, or to existing players, as a reward for continuing to use their games. A no deposit bonus is a reward offered without the need for a player to make a deposit of real money to be eligible. No deposit bonuses can be offered in many forms – for example, they could be an amount of virtual cash deposited in a player’s virtual wallet, which could be designed specifically for a game, type of game or for general use across the site.

Sometimes free spins will be offered on slots games to get new players involved in the offerings on site without needing to part with cash first, or as a reward for players who have already spun the reels a lot.

Deposit Bonus

The clue is in the name – a deposit bonus is a bonus offered when a player makes a deposit at an online casino. It is often also referred to as the welcome bonus, as they serve similar functions and have the same requirements in many cases. In other words, both a deposit bonus and a welcome bonus will usually require a player to sign up for an account, then make a deposit of real money into their virtual wallet. This will unlock the bonus, which will be either a match up to a certain amount, free spins or a fixed amount of virtual cash to be spent on casino games.

Deposit bonuses can often come in stages, with different rewards being offered for subsequent deposits. The most common patterns seen for deposit bonuses offered in stages go up to the third or fifth deposit, with many offering a match bonus for each deposit.

Daily Bonuses

Daily bonuses can make life at an online casino much more varied and interesting. The casino will create incentives for players to keep logging into the site and playing games on a regular basis by introducing bonuses, rewards and prizes based on them performing a particular action.

Sometimes this can be as simple as signing in on a particular day of the week, and receiving a benefit such as 10 free spins in return, or there could be clues that require unlocking in order to receive a mystery prize, a chance to win a grand prize or a special bonus game available for a limited time only.

Weekly Bonus

In some ways, the weekly bonus is similar to the daily deal. This offer involves a reward which is given on a weekly basis to players, often requiring certain actions on their part. Sometimes, this can be as simple as logging in a certain number of times or being active for a certain number of hours. On other occasions, you may have to meet particular requirements in order to be eligible for a reward.

These types of bonuses are regularly seen as part of a VIP club’s perks, and require players to wager a certain amount of money each week in order to receive their bonus.

Live Casino Bonus

Most casino bonuses will be focused on slots and table games, but if a site has a large selection of live dealer games, then bonuses and offers can be applied to this category too. These bonuses will often come in the form of competitions, such as being in the running to win a fixed amount of cash for playing live baccarat or blackjack, or being allowed free spins on live roulette.

If you want to be able to use live casino bonuses and plan on playing these games more regularly than other kinds, do your research to find a casino operator that will meet your needs.

Wagering Requirements

Should you opt to receive a casino bonus on top of one of your deposits, the likelihood is that it will also come with something known as wagering requirements. These basically also determine the amount of funds you need to have wagered on games before you’re able to make a withdrawal of any bonus funds. It sounds more complicated than what it actually is, but let’s try to make it a little simpler for you.

Let’s say that you take the deposit bonus mentioned earlier, 100% on top of £100. This sees you start your gaming journey with a total of £200. So that’s £100 of your own money and a further £100 in bonus money. Wagering requirements usually relate solely to the bonus funds, but can also incorporate the deposited funds as well. Terms and conditions will often state something like, “bonus funds need to be wagered a total of 35 times over”.

In order to figure out the sum of the wagering requirements for you, you simply need to multiply your casino deposit bonus by the requirements. In our example, you received a deposit bonus of £100, so essentially, 100 multiplied by 35 equates to a total of £3,500. This is not an amount that you need to win, or an amount that you need to lose either, it is simply the total amount in bets that you need to place before you can withdraw any bonus funds or winnings.

Every wager you place on a game will count towards this total, so you could place a wager of £50 on a game, win the round and receive a profit of £50 on top. You could then place a wager of the same amount and lose it, before going for a third game of the same amount, and win another £30 on top. Despite the fact that you’ve won £80 and lost £50, you’ve still placed three separate bets of £50, equalling £150 in total. Therefore, if your wagering requirements stand at £3,500, as in our example, a total of £150 will be deducted from this.

Why do Casinos have Wagering Requirements?

They are a way of protecting themselves financially and come on the back of every single bonus offered. From the free trial bonuses to free spins, wagering requirements will be mentioned within those specific terms. Imagine a casino offering all new players £100 for signing up with no hidden catches – they’d all be cashing out. Wagering requirements are in place to stop the loss of huge sums of money on the casinos part – they were brought in when bonus whoring began a few years back.

If you’re wondering what bonus whoring means, it’s a term to describe players signing up to casinos using multiple accounts, just to make ‘free money. It was a disaster for the online gambling industry. With tougher regulations on bonuses over the last couple of years, those loopholes used by those looking to gain and not spend have been closed. But, at the end of the day it means you could be spending a shedload of cash just try and make a withdrawal.
