What Are 3rd Deposit Bonuses and How They Work

Keeping players entertained is vital for any casino. Fortunately, that’s where a third casino deposit bonus comes in and helps. Such a reward is often paired with free spins for the casino’s most popular slot games, but it may also include additional funds or cashback rewards.

While GB casinos have different third deposit bonuses, most follow the same principle regarding how it works. They only apply to new players who’ve deposited at least twice and claimed their first two deposit bonuses. Once these users make their third deposit, they can claim the rewards and check qualified casino games.

It should be noted that there are often specific terms and conditions regarding third deposit bonuses. For example, there are particular wagering requirements for withdrawing cash. Therefore, players must pay close attention to these to be eligible.

Pros and Cons of These Promotions

While it’s often a good idea, a third deposit bonus also has flaws. Let’s break these down so you’ll know what you’re dealing with:

Pros
Extended Gameplay: A third deposit bonus lets you continue the fun longer. Even if you run out of your primary funds, you can continue playing thanks to the funds and spins from the bonus.
Rewarded Loyalty: While they often exist as part of a welcome bonus, they’re beneficial for players who keep depositing. Thus, it can also be said that they reward loyalty.
Additional Rewards: Third deposit bonuses are typically paired with free spins for popular slots. However, they might sometimes return a portion of the deposited money.

Cons
High Wagering Requirements: One of the most common requirements associated with a third deposit bonus is that players must wager a specific amount before withdrawing. This amount is often a multiple of the bonus, making betting more challenging.
High Deposit Requirements: Only players who deposit considerable sums of money are eligible for the third deposit bonus. That makes this bonus less than ideal for players with smaller budgets.
Restricted Usability: A third deposit bonus is sometimes limited to particular games. Here, specific slot games represent the most common type.

As you can see, both benefits and flaws are present in these casino bonuses. However, if you’ve already started playing on a particular website, there’s no reason not to claim one. With that said, let’s see the types of bonuses you can claim.

Exploring the Kinds of 3rd Deposit Bonuses You Can Expect

If you’re into online gambling and a frequent visitor of UK casino sites, you’re likely already aware that the casino’s third deposit bonus can come in all shapes and sizes. They typically include the following:

Welcome Offer

Usually, the 3rd deposit cash bonus is part of a casino’s welcome package. Such a package covers the first three deposits a player makes, and its goal is to get players to keep playing and depositing.

No Deposit Deals

While they don’t require a deposit, these no deposit bonuses include free spins or small cash rewards. They allow freshly registered players to test the casino’s games and features without investing more money.

First Deposit Promotions

As its name implies, the first deposit bonus is the first offer in a welcome package that requires a deposit. It typically includes a 100% bonus match or free spins to keep the players entertained longer.

Second Deposit Bonuses

Although the bonus match here is smaller and there are fewer free spins, the goal of the second deposit offer is to carry the momentum of the first one. As such, it incentivises players to continue playing and depositing by rewarding their devotion to the site.

Third Deposit Deals

As the interest starts fading, casinos up the ante again, making the third deposit bonus as good as the first one or even better. These bonuses typically provide more free spins and a better bonus match percentage but can also include access to exclusive games.

Deposit Match Bonuses

While welcome packages are an excellent deal for fresh players, other third deposit bonus options, like the standalone third deposit match bonus type, are often better. Here, the casino matches a portion of your deposit. For example, a 50% match bonus can make a £50 third deposit worth £75.

Reload Bonus on 3rd Deposit

Unlike the aforementioned welcome package bonuses, reload bonuses target existing users and incentivise them to return and continue playing. They combine a deposit and a loyalty reward, often including additional funds and free spins.

Bonus for Existing Players

Although being a welcoming casino for new players is vital, casinos also know the importance of rewarding their existing players. As such, they also reward these users with lower wagering requirements and other similar conditions.

Free Spins

While many of the abovementioned bonuses include free spins, some casinos in the United Kingdom have third deposit bonuses that specifically focus on these offers. They allow users to spin the wheel and try specific slots without investing a cent more, making them well-liked as standalone promotions.

Overall, it’s evident that there are multiple types of third deposit bonuses, and the ones you encounter will depend on the GB casino you join.
