What is a 400% Casino Bonus?
A 400% match bonus means that the casino will match your deposit by 400%. If you deposit $10, then the casino will provide you with $40 in bonus funds to play. In total, you have $50 to spend as you wish.
However, you cannot cash out this bonus money for free. Your deposit as well as the bonus are tied down to terms and conditions, most notably the wagering requirements.
Before you can cash out your winnings, you would need to wager your deposit + bonus a number of times as stipulated in the terms.
While a 400% deposit bonus is good on paper, you also need to be aware of the threshold the casino has set for this bonus. If you are making a deposit of $100 and claiming the 400% bonus, but the casino is only willing to match it up to $200, then you won’t get $400 in bonus funds, but $200.

Online Casino 400% Welcome Bonus
In most cases, a 400% deposit match is part of the casino’s welcome bonus package. Deposit offers of 400% are among the best welcome bonuses that online casino players can get, but only if the terms are fair. If you decide to take advantage of a bonus with such a high match percentage, you must carefully read the casino’s bonus terms and conditions. This is because not all deposit bonuses are created equal.
As a general guideline, the bigger the deposit match, the higher the wagering requirement of the bonus. While most welcome bonuses have wagering requirements between 25x-35x the bonus amount, 400% casino bonuses tend to have much stricter requirements. Sometimes it can be as high as 75x the bonus amount. If you manage to find a 400% bonus with wagering requirements that are less than 50x the bonus amount, it’s usually a good deal.
Tips when Playing with a 400% Bonus
New players to the online gambling world might misunderstand the terms and conditions that come attached to their bonus. Terms for any bonus you are thinking of claiming must be fair and easy to follow.
For example, most bonuses should be valid for a period of 30 days. It is not uncommon to see operators providing a short 3-7 day validity to their bonuses.
Here are some of the most common terms you should watch out for:
Betting requirements
If you love playing a specific type of game, you should carefully read the terms of your 400 casino bonus. In the majority of casinos, live casino games, as well as RNG card and table games, do not contribute to the wagering requirements.
Additionally, a 400% match deposit bonus usually comes with a stipulated minimum and maximum bet size for games.
You need to remember that failure to comply with the terms will result in failure to meet the wagering requirements.
Multiple deposits
Some gambling operators might advertise as offering a 400% match bonus, when in fact, this number would be split into 100% bonus offers split over 4 deposits.
Pay careful attention to the minimum deposit so you don’t miss out on the opportunity to claim the bonus.
Eligible Payment Methods
Some online gambling sites can restrict specific payment methods from their welcome 400% bonuses. This usually applies to e-wallet options such as Skrill, Neteller and PayPal.
Though it is not always the case or across the board, if you prefer using these e-wallets, you may want to double-check, you are not exempt from claiming the offer.
Caps on winnings
A big bankroll allows players to play more games and possibly hit big wins. Caps on winnings don’t always apply but they can throw a damper on things, especially if you hit a substantial win.
A cap on winning entails a sum of money that the casino is willing to pay out should you meet its terms. If there is a cap of $100 and you have generated $500 with your bonus, then you will only receive $100 in withdrawable cash.
Caps on winnings are not always in place, but with such a generous offer, it is highly likely, We advise you to keep an eye out for it.
