The Best 300% Deposit Casino Bonuses

As the size of the casino industry grows, so does the size of online casino bonus offers. When online casinos first came about, they used to offer new players match deposit bonus offers that were usually around 100% up to $200. However, because the competition between online casinos is much tighter, the casino bonuses are becoming ever more competitive – which means that now some offer 200% casino bonuses and even 300% deposit bonus offers. However, the bigger the deposit bonus looks on paper, the more important it is to check the terms and conditions, as these can often prove to be as hefty as the casino bonus size.

Here, at CasinoReviews.net, we will look at the very best 300% deposit bonus offers to see which ones are worth taking up and which of these online casino bonuses are the best. We will also guide you so that you can understand for yourself what you need to look out for when choosing a 300% casino welcome bonus.

How We Rate the Best 300% Deposit Bonus Online Casinos

So, when you look at casino welcome bonuses that look very similar in terms of size, how do we rate one over the other? Well, here are the areas that we look at when rating the online casino and its 300% deposit bonus.

The Size of the 300% Deposit Bonus

Just because there are several 300% deposit bonus offers, it doesn’t mean that they are all equal in size. For example, one online casino could offer a 300% casino deposit bonus up to $300, whereas another online casino could offer 300% up to $1500 or higher. Some could also offer an additional free spins offer to play on selected real money online casino games.

Moreover, one 300% deposit bonus could be valid for just the first deposit, whereas another casino might offer a welcome package spread out over several different deposit bonuses. These are always popular as you can get rewarded for not just one deposit, but maybe even three or more.

Free Spins Offers

In addition to the 300% deposit bonus, we always look to see which top NZ online casinos offer additional free spins or bonus spins in addition to the bonus funds – even better if these are no deposit free spins. We always look for a 300% deposit casino bonus with free spins on top as this gives players the chance to enjoy casino games and slot machines as much as they like.

Terms and Conditions

The best casino bonuses will attach fair and transparent terms and conditions to their first deposit bonus. So, before we recommend any 300% match bonus offer, we will always read the small print, first of all, to look at the wagering requirement attached to the bonus amount and free spins bonuses. We will also look at the maximum cash winnings and max withdrawal, the minimum deposit required to claim the casino bonus, the expiry date etc. The best new customers welcome bonuses will be fair to New Zealand players. We will look at these terms and conditions in closer detail later on.

How Many Promotions The Casino Sites Offer

Aside from the 300% bonus for new customers, what other promotions does the casino offer for existing players? We look for such offers as free spins for new online slots, live casino bonuses that can be used on live dealer table games, bonus codes for existing customers that offer players reload bonuses, cashback offers and more. The best online casinos don’t just offer 300% welcome bonus offers, but casino bonuses for all of their players.

Variety of Slot Games and Table Games

300% casino bonus aside, we look for the quality of the casino site that is offering the welcome bonus. This includes the variety of online and table games in the casino room. We pay attention to casino operators that offer titles from a variety of casino and slot game providers. When players start gambling, it is vital that they open a new account with a casino that has an array of options. All of our recommended casinos will offer titles from providers such as NetEnt, Red Tiger, Microgaming and more so that your gambling journey isn’t just about whether you win big or not, but also so that you have fun every time you place bets on a whole host of different slots and games!

Fair and Trustworthy

When you make a real money deposit at an online casino, you want to make sure that you are playing on slots at a safe, fair and transparent casino. As such, we will only recommend 300% match bonuses that can be found on trusted casinos. All casinos we recommend on our site, whether they are UK casinos, European casinos or Australian casinos, will be regulated and licensed by regulatory bodies such as the UK Gambling Commission. This means that the casino is safe and fair not just for UK players but also for New Zealand players. Every new casino bonus we add to our list will be fair, trustworthy and transparent.

Banking and Customer Service

When you make your first deposit on a casino site, you want to be sure that it is being looked after, and that there is always someone there that can help you if needed. Most casinos will make sure that they have customer service available 24 hours a day, or at least for the majority of waking hours. Ideally, the customer service will also be available on the phone, live chat and email. We also look at the banking to make sure that the brand offers the best online casino payment methods. We also look for instant deposits and fast payout casinos.

Understanding 300% Welcome Bonus Terms

As we stated before, a 300% deposit bonus is only as good as the terms and conditions attached to it. So, before you claim your welcome bonus, here are some things to look out for.

Wagering Requirements

The most important of all the terms and conditions attached to any welcome bonus, free spins or match bonus offer is the wagering requirements. This determines how easily you can withdraw your bonus funds or free spins winnings – and how much of your own real cash funds you have to spend in order to do so. Ultimately, the wagering requirements determine whether or not you can claim your winnings.

Example 1: You deposit $50 and claim your 300% casino bonus of $150. Your welcome bonus terms and conditions say that the deposit and bonus funds are subject to 30-times wagering requirements. This means that in order to withdraw your bonus funds and casino bonus winnings you will need to wager 30 x ($50+$150) = $6000 of your own money.

Example 2: You deposit $5o and claim your 300% casino bonus of $150. Your welcome bonus terms and conditions say that bonus funds ONLY are subject to 30-times wagering requirements. This means that in order to withdraw your bonus funds and welcome bonus winnings you will need to wager 30 x $150 = $4500 of your own money.

Example 3: You make a minimum deposit at a casino of $10 to claim 300 free spins. The 300 free spins welcome bonus terms and conditions state that free spins winnings are subject to 30-times wagering requirement. This means that if you win $50 on your free spins then in order to withdraw these free spins first deposit bonus winnings you will need to wager 30-times $50 winnings = $1500 of your own money first.

This means that when you look at the wagering requirements, you need to see whether you need to wager your first deposit bonus funds only, or the bonus funds plus your first deposit. This makes a big difference.

Bonus Code

You need to see whether your first deposit bonus needs a bonus code first. If you don’t enter the required bonus code before completing the qualifying deposit, then you won’t be able to claim the offer at all.

Max Withdrawal

This is the maximum amount of money you can win from the bonus or free spins. The best bonuses will not cap the winnings. This is usually found on no deposit casino bonuses or no deposit free spins. The maximum cash winnings will be specified in the terms.

Minimum Deposit

This is the minimum amount of money you have to deposit into your account in order to claim your 300% bonus offer. This is usually between $10 and $20.

Selected Games

This is generally for free spins offers, which are only valid on selected online pokies. However, there may be cases when your 300% bonus is only valid for certain slots and table games. These generally won’t include live casino games. Moreover, it’s worth noting that you can usually only fulfil your wagering requirements on selected slots – as card games and casino games often have a lesser weighting, which means you have to play even more of your own money.

Validity

Welcome bonuses, deposit bonuses and free spins will all come with an expiry date. Usually match bonus offers come with a longer expiry date of around 30 days, whereas deposit and no deposit free spins usually have either a 24 hour or 7-day expiry date. In this time, not only do you need to use your match bonus or free spins, but you also need to fulfil the wagering requirement in this time as well.

Other Types of Deposit Bonuses

So, aside from 300% match bonus offers, what other offers should you be looking out for? Here are some of the other deposit bonuses to look for.

500% Casino Bonus

This one is rare – giving punters 5-times their first deposit value in bonus funds. However, they do exist and they are always worth looking out for.

Neonvegas Review

Neon Casino

The best example we have of a 500% deposit bonus is Neon Casino, which currently offers new customers 500% up to $500. However, this is structured and works in a different way than the standard casino bonus as you have to fulfil the wagering requirements of the bonus before you can use the bonus. So, how does this work?

Well, the 500% casino bonus comes with a 20-times wagering requirement, which is pretty decent. Normally, you make a qualifying deposit, claim your bonus and then fulfil the wagering requirements before withdrawing winnings but this is different as you make your deposit, and your deposit bonus is locked until you fulfil the wagering requirements.

So, if you deposit $50 you will get a $250 casino bonus. However, this $250 bonus remains locked until you have wagered this $250 20 times. You have two days to do this. So, after registration, in two days you need to wager 20 x $250 = $5000 of your own money. When you have done this, your $250 bonus will be released and you can then claim the bonus funds and any winnings from it straight away. To claim the deposit bonus, you will need to enter the bonus code NEON on registration.

100% Casino Bonus

This is the standard casino bonus that many online casinos offer. You simply make a minimum deposit and the casino will double your deposit with casino bonus funds.

VoodooDreams Casino Review

Voodoo Dreams

A good example of this 100% deposit bonus offer is Voodoo Dreams, which offers new customers a 100% deposit bonus of up to $100 plus 200 free spins on Book of Dead.

This deposit bonus comes with a minimum deposit of $20 or more and then you will have your 100% casino bonus credited into your account straight away. You will also get 20 free spins on Book of Dead every day for ten days. The 100% deposit bonus is subject to 30-times wagering requirements of both bonus funds plus deposit, and the free spins winnings are subject to 40-times wagering requirements.

200% Casino Bonus

The 200% bonus is becoming more popular than ever and more and more casino sites are offering this now. This is a bonus that triples your first deposit.

Casimba Review NZ

Casimba

Casimba is a great example of this, currently offering new players a 200% bonus up to $5000 plus 50 free spins on any NetEnt slot, plus 500 loyalty points. This is just the first part of the welcome package. In total, over three deposits, new customers can claim up to $6,500 in bonuses and 125 free spins. To claim the first 200% bonus, simply make a qualifying deposit of $20 or more and you will instantly get your bonus money and 50 free spins.

The 200% bonus funds come with a 35-times wagering requirement of both bonus and deposit. The bonus also has a maximum bet of $5 allowed.

Free Spins

There are also a number of free spins bonuses available, which could be 20 free spins, 100 free spins, 300 free spins or more. Free spins bonuses give you the chance to play on selected slots as chosen by the casino.

PlayOJO Casino Review

PlayOJO

The reason that this one stands out from the rest of the free spins bonuses is because it is not attached to a deposit match bonus and is a standalone bonus and is completely wager free.

On sign up, new customers can claim 80 free spins no wagering on Book of Dead. In order to claim this bonus, you simply need to register a new account at PlayOJO and make a minimum deposit of $10 or more. You will then get 80 free spins credited into your account within 24 hours of making the qualifying deposit.

The beauty of these wager-free free spins bonuses is the fact that terms and conditions are few and far between. Simply use your free spins within 24 hours of receipt and you can claim any winnings you have.

300% Welcome Bonus FAQs

๐Ÿฅ‡ What Are 300% Casino Bonuses and Why Do Casinos Offer Them?

Well, 300% casino bonuses are exactly what they purport to be – bonuses that reward players with 300% of their initial deposit. So, for example, if you deposit $100 then you will get $300 in bonus funds, giving you $400 to play with (remember to look for bonus codes). The reason online casinos offer bonuses such as these is to attract new players to their casino site. Because there is a lot of competition between casinos now, casino sites must do everything they can to attract new players. So, the bigger the bonus, the better – and 300% bonuses are pretty big!

๐ŸŽฐ Are 300% Casino Bonuses Free to Play?

No. They are not free. Firstly, to claim your bonus, you need to make your initial deposit. The minimum first deposit is usually $10 or $20. Then, after you have claimed the bonus, you need to fulfil the wagering requirements, which also involves you having to spend your own cash funds. Yes, 300% bonuses are generous, but they are certainly not free to play!

โ“ What Are No Deposit Bonuses?

No deposit bonuses are those that you can claim on registration without the need to deposit your own money. You simply need to open a new account, check whether any bonus codes are required and your bonus will be credited instantly. There will be terms and conditions attached, however, including wagering requirements, max winnings and validity.

โญ Are 300% Casino Bonuses Better than 100 Free Spins Bonuses?

Well, this very much depends on what kind of player you are and what terms and conditions are attached. 300% casino offers are generous and more flexible, so you can play them on a wider variety of games, whereas free spins offers are for selected slots only. However, if the wagering requirements are too high on the 300% casino bonus, you may well be better off opting for the free spins offer.

๐Ÿ’Ž Can I Withdraw My Winnings?

Yes, you can withdraw your winnings from any bonus as long as you fulfil the wagering requirements first within the time limit. So, if you claim a $150 bonus with 30-times wagering requirements then you will need to wager $4500 first before withdrawing your winnings. There may also be a max winning cap attached to the bonus that you need to be aware of.

๐Ÿ‘‰ How Can I Claim a 300% Casino Welcome Bonus?

Claiming your bonus is simple. Just click on the link from our recommended casino bonuses above and head over to the registration page. Sign up for a new customer account and enter your details plus any bonus codes required. Then simply make your initial qualifying deposit and your bonus will be credited directly into your account.
