300% Bonus Sites

Online casinos offering a 300% deposit bonus.  22 sites were found. Terms and conditions and wagering requirements apply.

 

300% deposit bonuses are great if you want to make your initial deposit last a little longer and get the most out of your game play. Deposit bonuses are designed to give you a little more for your money when you’re trying out a new site as it allows you to play for longer, try out more slots and games and get a better feel for a site with your bonus money. 

If you registered with a casino site that offers a 300% first deposit bonus, this means that the first time you make a deposit, the casino will give you a bonus of 300% the amount you deposited. So if you deposit £20, the online casino site will give you a further £60 in bonus money to play with.

Do all online casinos offer a deposit bonus?

No not all, but most online casinos, mobile casinos and slot sites do have some form of bonus or free spins as a welcome offer to new players. 

A deposit bonus means you will receive a bonus of some form once you have made an initial deposit.

A no deposit bonus means the online casino will give you bonus money to play with without you having to credit your account at all. Although the chances of actually winning any real cash from this are slim to none, it’s a great way to test out a new casino site to see if it’s somewhere you’d like to deposit and continue playing at. 

Free spins with deposit offers’ mean that a casino will give you a set number of free spins once you have made the minimum deposit amount.

What are the advantages of playing with a 300% bonus?

The main advantage is that any kind of bonus allows you to play for longer. If you deposit £20 and receive a 300% bonus, that gives you an extra £60 worth of bonus money to play with, so three times more playing time. If you’re trying out a new online casino for the first time and have additional bonus money to play with, this gives you longer to try out the site and play more games, test out how easy the site is to navigate and ultimately decide if you want to continue playing there and depositing more money. 

Are there any disadvantages of claiming a 300% deposit bonus?

Free bonus money to spend? How can there be any disadvantages to that you ask? Well, not everyone likes to claim a deposit bonus and if you do, it makes it more difficult to win real cash. Along with a deposit bonus come terms and conditions which usually state the maximum amounts you can either bet per spin or win from a single bet, and the wagering requirements.

When you’re just playing with real cash, you win real cash, and for this reason, some players chose not to claim a bonus and just play with real money instead.

What are maximum wins and bet limits?

The significant terms are usually displayed alongside the bonus offer and often say things such as ‘max win £20, max bet with bonus £5’. If a slot site has these terms, it means that if you claim a bonus, then the maximum amount you can win at any one time from that bonus is £20. Even if you hit a jackpot prize, it doesn’t count and the highest amount you can claim is still £20. 

With regards to maximum bets, these are usually capped at around £5 per bet/spin when using bonus money. Because you’re playing with bonus money, it would be much easier to place a much higher bet and gamble with larger sums in order to win much larger amounts than if you were playing with your own cash. For this reason, the maximum bet limit is added to many bonus offers. 

How do wagering requirements affect my 300% bonus?

Wagering requirements are another term which hinders your chance of winning real cash from a bonus. Wagering requirements are the amount of times you have to bet your bonus money before it becomes real cash that you can withdraw. So with a 300% bonus, if you deposited £20 and received a £60 bonus and the wagering terms were 40x, that means you would have to wager £60, 40 times (£2,400 in bets) before you were eligible to withdraw your winnings.

Wagering requirements vary widely between casino sites with some having low 5x wagering and others having high 60x wagering.

As you can see, unless you won a significant amount (and this may be stopped by a maximum win limit) or were playing in a casino with low wagering,  by the time you had played through your wagering requirements, you would be left with little to none. 

So bonuses are great if you realise you probably won’t be able to win real cash with them and just want to enjoy a little extra game play. 

Are there 300% bonus offers with no wagering or restrictions?

Believe it or not, there are online casinos and slot sites out there that give you bonus money with no restrictions at all! They’re not particularly common, but a growing number of gambling operators are offering players deposit bonuses without any wagering, win limits or maximum bet caps. The only stipulation is that you have to play your bonus money, you can’t just withdraw it into your bank account. 

One of the first and most well-known online casino with no wagering or restrictions is PlayOJO. They have a no-nonsense, no restrictions, no wagering casino site and refer to themselves as ‘the fair online casino’. Other brands are following suit too as they realise many players prefer the ‘no frills’ approach with no complicated hoops to jump through. 

The bonus amounts may not be as high as some other online slot sites, however you have the knowledge that if you win, you keep it. 

Can I claim a bonus with any deposit method?

No, not always. If you want to claim a bonus, then check which deposit methods you are able to use. Because of the various fees operators have to pay for processing transactions, this means that deposit bonuses are sometimes limited to a particular banking method or certain methods are excluded. If a specific or several payment methods are not available to use when claiming a bonus, it will usually state this in the terms, with something along the lines of ‘deposit bonus isn’t available with Neteller or Skrill’. 

Now you know a little more about how deposit bonuses work, you can now check out all the casino sites with a 300% bonus.
