300% Matched Deposit Bonus Explained

A matched deposit is a common bonus type offered to casino players. Often used as the main part of a welcome bonus offer, matched deposits boost a player’s account funds by having the casino equal a portion of the player’s deposit. 

Standard matched deposit welcome offers are around about 100% up to £100 – a bonus of this kind gives players the chance to double their deposit value at no extra cost, since the casino is agreeing to front 100% of the deposit on top of the player’s contribution. So, if a player were to make full use of this deal, they’d land £200 in their casino account from a £100 deposit.

Although 100% up to £100 is about par for matched deposit offers to new players, they’ll be smaller for existing players, possibly around 100% up to £25. However, some welcome bonuses far exceed this amount, rising to 200% and even 300%. The way the bonus works remains the same, but if the offer is 300% up to £100, players would see their casino balance reach a grand total of £400 from a £100 deposit.

Before you start licking your lips in search of the best 300% matched deposit bonuses, it’s important to know that bigger doesn’t necessarily mean better. All casino bonuses must always be considered in conjunction with their terms and conditions; if wagering requirements are a factor, then players are likely to find that larger offers will rule them out of converting the bonus into withdrawable cash.

With this in mind, it sometimes pays to access only a portion of the bonus as opposed to the full amount – indeed, one of the best things about matched deposits is that they give casino players this freedom to choose.

How to Claim Your 300% Matched Deposit Bonus

At TopRatedCasinos, our mission is to provide the necessary information for online gamblers to find exactly what they’re looking for with minimal stress. That’s why we make it as easy as we can to point our users in the right direction. So, if you want to find the best 300% matched deposit bonuses, all you have to do is follow these simple steps:

  1. Take a look at our recommendations of the best sites and offers, consult leaderboards, read our expert reviews, and compare offers;
  2. Once you’ve found a site you like, click through to the casino using our links;
  3. We’ll take you straight to the sign-up page, where you’ll need to enter your details;
  4. Wait for the casino to complete its identification checks, submitting official documents – such as a passport or driver’s licence – when prompted;
  5. When these checks are complete, you’ll be able to make your first deposit;
  6. Select your payment method and key in the amount, making sure your deposit qualifies you for the bonus offer;
  7. Enjoy your bonus funds!

Benefits of a 300% Matched Deposit

Here are the main reasons for making use of a 300% casino welcome bonus. 

Opportunity to Try New Games

It’s a new site, which means it’s also a new games library. You’ll want to know if the games in the casino’s arsenal are suitable to your paying tastes, and matched deposits give players the opportunity to find out without staking too much of their own cash. Although it might prove difficult to walk away with any bonus winnings, players can use the bonus funds in their account to play and practice new games, find the titles they like, and be in with a better chance of winning cash prizes when it comes to playing with their own money. 

Test a Casino for User Experience

As well as testing out the casino’s games, you’ll also want to know how the site looks, feels and plays once you’re a registered member. Without matched deposit funds at your disposal, you might not be afforded the time to realise whether the site’s aesthetics and user experience features are awkward, ugly, or complicated. Large matched deposit bonuses give you the space to work this out for yourself without having to spend your own cash..

Additional Playing Funds

And of course, accessing a 300% matched deposit bonus means you’ll triple your playing funds at no extra cost. There are very few opportunities in life to immediately triple your investment, but playing at a 300% welcome bonus casino is one of them. 

300% Matched Deposit Terms and Conditions

As we alluded to above, you’ll need to pay close attention to any terms and conditions associated with the bonus. These conditions often present significant barriers to those looking to convert bonuses into withdrawable winnings, and players will need to read all the details in the small print to avoid any nasty surprises. Here are the T&Cs you’re likely to run into with this kind of bonus. 

Wagering Requirements

The biggest obstacle to matched deposit bonus success is the wagering requirements – a condition that commits players into wagering their bonus a certain number of times. If players don’t fulfil the wagering requirements, they won’t be able to request a withdrawal of any winnings connected to the bonus. 

The value of the wagering requirements will depend on the generosity of the casino, but are usually set anywhere between 25-50x the bonus. The 40-50x mark is considered steep, 30-40x is about industry average, and anything set at 25x and below is pretty good value. 

Here’s how these requirements work: let’s say the 300% matched deposit bonus is applicable up to a value of £50 and comes with a wagering requirement of 30x. If players made full use of this offer, they’d be required to wager a total of £1,500 (50 x 30) before they could make a withdrawal request. With this example, it’s clear to see how wagering requirements can easily scupper plans to convert bonus money into winnings. 

Game Weightings

The influence of wagering requirements doesn’t stop there, either. With game weighting restrictions, games are split into different wagering categories: some games are weighted at 100%, meaning that the full weight of any wagers on that game will contribute 100% towards the requirements, but others can be as low as 10, 5, or even 0%. 

Online casinos will publish the full list of their game weightings structure in the bonus’s terms, but as a general rule, wagers on most slots are weighted at 100%, while table games such as roulette and blackjack tend to have smaller weighting percentages to their name. If you have ambitions of completing the requirements, make sure you only wager on games weighted at 100%!

Time Limits

Time limits are fairly self-explanatory: if the clock runs out, your bonus funds will expire. The important distinction to make with time limits is whether they apply to the bonus as a whole, or to the time it takes to fulfil the wagering requirements. Make sure you keep one eye on the clock if you’re attempting to complete those pesky requirements. 

Game Exclusions

You may also find that you don’t have free rein to play whichever game you like with bonus funds. This is due to game exclusions, where casinos only make certain games eligible to play with the bonus. Before you commit to a bonus – particularly one as large as a 300% matched deposit – make sure at least some of your favourite titles are available. 

Payment Exclusions

There may be restrictions on the type of payment method that’s allowed to access bonus offers. Deposits from debit cards will always be safe in terms of bonus eligibility, but newer banking technologies, such as e-wallets like PayPal, are often excluded by gambling sites

Winnings Caps

To prevent players from bankrupting the site with incredibly successful bonuses, online casinos will usually always include a clause that limits how much stands to be won. Winning caps may seem like an unjust restriction on gambling freedoms, but really they ought to be seen as useful on-site limiters.

Bonus Calculator

Our bonus calculator tool makes it easy to find out the amount you’ll need to wager in order to meet your bonus’s wagering requirements. Enter the deposit value and percentage, the wagering requirements, the contribution percentage of your favourite game, and whether your casino includes your deposit in the calculation. All of the details you’ll need can be found in your casino’s bonus terms and conditions. Once that’s done, click ‘Calculate’!

Other Welcome Bonuses

Casino welcome bonuses come in all shapes and sizes. Matched deposits are a common option, but here are some other bonus types to look out for.

Free Spins Bonuses

Often offered as part of a welcome package alongside matched deposits are free spins bonuses. These can only be used on the site’s collection of slots, where players can use the spins to earn as much cash as possible. When free spins are offered to existing members, players will usually need to make a minimum deposit.

No Wagering Bonuses

No wagering bonuses remove wagering requirements from the equation. This means that any time this bonus is offered, whatever players win is rightfully theirs, and they’ll be able to make a withdrawal as soon as they wish. 

No Deposit Bonuses

No deposit bonuses function in exactly the same way as matched deposits, except there’s one key difference: no deposit! When these welcome bonuses are on offer, players’ accounts will be credited with funds as soon as they’ve signed up to the site, although the value of these bonuses will be significantly less than their matched deposit cousins.

Our links, leaderboards, and expert reviews make it easy for users to compare sites and bonuses, and to pick the one that’s right for them.
