What is a 300 Deposit Bonus?

Having provided great detail as to where you can acquire this incredible first deposit casino bonus, let us now explain what it is and why it is one of the best deposit casino bonus promos you can claim. The 300% deposit bonus is often known as a reload bonus, matched deposit bonus, or a matched deposit welcome bonus. Despite the different names, the role of the bonus is the same. What you pay as a deposit, the casino will add 300% on top of the value. So, if you were, for example, to deposit 100 dollars, you would get 300 added to this. It is a huge upgrade in a player’s balance, providing more security to your own funding, and allowing for more game time. T&Cs apply to such a bonus which is why players that are interested in receiving this reward should always refer to the terms to understand the rules of use.

What are the conditions required to be eligible for a 300 Deposit Bonus?

Because the 300 welcome bonus is a different promotion to say a standard 300 deposit bonus reload offer, there are subtle differences in the T&Cs. The expiry date will be different, and the initial deposit amount will be different, as is the method of banking that will be allowed to claim the welcome bonus from the reload bonus. You must also bear in mind that the rules and the terms are all going to be different across all the casinos. Now, while it is impossible to log all T&Cs for all casinos that do and have provided the 300 deposit bonus, we are going to give a brief reveal of the basics that should be within all T&CS when it comes to this reward.

Bonus expiry time limit

All promotional bonuses have a shelf-life, which is why all rewards are subject to change. Some bonuses, mainly welcome bonuses come with reduced use-by dates which are traditionally 7 days. When it comes to long-standing promotions, they can be around for months and even years in some cases. Always make sure that you note the date of expiry before you commit, and watch out for the casinos that still advertise old promotions on their news and blog pages.

Minimum Deposit

To trigger any bonus offer requires a deposit to be paid unless it specifically advertises with no deposit required. The deposits that are asked all have a minimum value that needs to be matched. Players can pay above the minimum amount if they want a greater return. To help players that might be wanting to budget their funds, there are a series of minimum deposit casinos. Examples of these include the $1 deposit casino NZ service, and the $2 deposit casino NZ service. These platforms will help those that are unable to pay in $10 and $20 deposits at a time to play the games they love.

Payment Methods

Casino bonus promotions can have terms that are relative to specific online casino payment options. The most common example of this is the 300 deposit welcome bonuses. Many casinos will not allow first deposits to be made via e-wallet methods because they provide anonymous transactions. In such instances, new players would need to make a first deposit payment via Visa, MasterCard, or Bank Transfer to claim the welcome bonus. Once this is done, then the player can revert to an e-wallet service for future banking. Another example is Bitcoin bonuses. Clearly, you need to be paying in crypto to be able to reclaim a Bitcoin bonus.

Wagering terms

The wagering terms are also known as wagering requirements, which are actually withdrawal policies. Now, we do not believe that they are at all fair, but because the casinos refer to them and discuss them in the T&Cs regulators have approved the withdrawal conditions despite the massive costs involved. The approval comes from regulators because players are given a clear choice, so the terms are deemed fair. Essentially, nearly all promotions have a wagering requirement. This is the requirement to pay in more deposits before winnings made from a bonus can be released. Now, an example of this would be the more common 35x wagering requirement cost. If you receive a $100 bonus, then you would have to further pay in $3,500 before the wins from your bonus can be withdrawn. It also doesn’t matter how much you win. If you won $5, you can withdraw until the wagering cost is met. But paying the wagering is optional, as you can always forfeit your winnings if the overall payment surpasses the bonus winnings. The wagering only becomes beneficial to pay should the value of what you win be greater than the cost of the wagering requirement.

Winning Limitations

Winnings can be capped by the bonus terms and conditions. It is rare for this to happen but this is a reality. Now, it is even rarer with a 300 deposit bonus, but do check the T&Cs to make sure as the casino is giving big money out, they may wish to reduce the opportunity to further take more money from them. Also, note that winnings are also limited by way of withdrawals. Not all casinos will let you cash out a million dollars. Commonly, a casino will have a $30,000 withdrawal limit per day, however, not all fall into this way of banking. Some casinos are limited to $4,000 per day, so be aware that cashing out a big win, might take a while to land in your bank account.

Player Type

There are three distinct player types: Casino Members, VIP Members, and New Members. There are 300 deposit bonuses out there that are specific to each group relative to the promotion being offered. With welcome bonuses, they can only ever be claimed by new members. Any 300 deposit reload bonus can be scooped by existing casino members and VIP members. Should there be a 300 deposit bonus offered in a VIP service, then only VIPs can claim the reward.

Games Limitations

The credit from a 300% matched deposit bonus may be restricted. The T&Cs will identify what games can and cannot be played with the credit. It may generally be for slot games and not live games, in some cases, the money could be used for all types of casino games. With some 300% bonuses, the offer may also include bonus spins. These additional spins may also be limited to certain games, often they will be noted on the promotion.

How to Claim a 300 Deposit Bonus

If you by now have 300% deposit bonuses on the brain, then you’re probably wondering how to get your hands on them. Well, the process is simple. Just follow these steps that take you from the registration process to the receiving of the reward.

  • Register with a casino.
  • Find a 300 deposit bonus and read the T&Cs.
  • Make your first deposit and apply any promo or bonus code if required.
  • You will instantly receive your 300% addition to your balance.
  • Load an eligible game and begin playing.

Bonus codes are found within the T&Cs. They aren’t overly common and are only handed out by the casinos that have multiple bonus offers throughout their site.

Reasons to Choose a 300 Casino Deposit Bonus

Bonuses are optional aids, and when presented with a chance to gain 300% more on top of your balance it kind of makes sense. There are benefits, especially for players that are limited to a smaller budget. However, you should only be choosing all bonuses based on their fairness. If the T&Cs are not right for you, then you can wait for one to come along that is just right. It’s always important to read the terms before making any financial commitment. The terms let you know about the deposit range, what games are playable, when the bonus ends, and what the wagering requirement costs are.

Bonuses are solely an aid to assist players, there is no guarantee that you will win with them. The service of casinos is not about paying out money to everyone. Casinos are firstly about making money; they are a business. Secondly, casinos are there to entertain adults, and thirdly, they provide the potential to win, but wins are only based on luck. Please approach online casinos sensibly and note that all New Zealand casinos provide account tools to limit deposit values and they provide support to external organizations like
