Your Guide for Finding the Best 400% Casino Bonus
The key to finding a good bonus is not to jump at the first one you see. Visit Crikeyslots and let your eyes wander over all the online casino bonuses available. Theyâve all got something to offer, and no matter what your preferences, youâre sure to find one you like the look of above all others, especially with a little help from me.
400% Matched Deposit Welcome Bonuses
A 400% matched deposit bonus might sound like an incredible deal, but the key is to look at the full package, game selection, wagering terms, and any restrictions that might make it less appealing. Some casinos structure these offers with free spins, while others tie them to specific deposit methods or limit their availability to certain games.
For example, BetOnRed Casino has a 400% welcome bonus, but itâs split across the first two deposits, with the first deposit getting a 250% match and the second a 150% match. The catch? The bonus is only usable on slots from Pragmatic Play, like Gates of Olympus and Sweet Bonanza.
Meanwhile, N1Bet Casino has a 400% high-roller bonus, but itâs only triggered when depositing over $250, making it less accessible for casual players. Asino Casino, on the other hand, offers a 400% match up to $800 with 100 free spins, but the free spins are restricted to Elvis Frog in Vegas and are credited in increments of 20 per day.
Then there are the ones with steep wagering conditions. Lucky Tiger Casino gives out a 400% bonus but requires a 50x playthrough before any withdrawal, while Leon Casino offers the same percentage but limits max cashouts to 5x the deposit amount.
The real takeaway? A 400% bonus can be a great bankroll booster, but always check if the terms actually make it worthwhile, some of these offers look generous upfront but come with strings attached.
Matched Deposit, Free Spins Bonuses
If you like the idea of playing with 5 times the money you deposit, youâre sure to like the thought of getting some free spins to play, too. 400% matched welcome bonuses with free slots as an extra, will increase the number of winning combos youâll land.
Welcome Bonus Reloads
Welcome bonus reloads bring even more fun to the party. They give you the opportunity to make several deposits. Itâs worth considering because most casinos will only let you claim one welcome bonus. With a reload bonus you can carry on enjoying your 400% deposit match with each deposit; on the 1st, 2nd, 3rd, 4th, and sometimes even on the 5th deposit if the deal stretches that far â and some do.
No Deposit 400% Welcome Bonuses
Yes, you can even get no deposit 400% welcome bonuses, although they are quite rare. With no deposit bonuses like these, itâs the first deposit in a reload bonus that is the no deposit action. The reload deposits require real money.
Low Deposit 400% Welcome Bonuses
Youâll find many low deposit casinos listed at Crikeyslots. These sites specialise in offering welcome bonuses for deposits from as little as 1,2, 3, or $5. Admittedly, the number of slots or spins youâll get is a little on the low side, However, Iâve seen them go up to 50 or even 100 spins. But itâs also worth knowing that most casino bonuses, and in this I include 400% welcome bonuses, offer minimum deposits, typically from around 10 or 20 $.
Expert Tips for Maximising the Bonus Deal Enjoyment Factor
I wonât pretend my expert tips will ensure you win, but what I will stand by is that they will increase your chances of winning and will up the enjoyment factor of playing bonuses like the 400% welcome bonus. Hereâs what I suggest you do:
- Pick out bonuses that are on games with the best RTP percentages.
- Choose games that have a low, or low to medium volatility rating.
- Choose slots that have the most paylines.
- Before you play the game via the bonus, play the free slot version youâll find at Crikeyslots.
- Wager low stakes for more spins.
- If you win and are offered a âdouble (or more) or quitâ gamble – ignore it.
I always say you should play for fun, not just to win. Winning is great, but if you become fixated on it, you might start chasing losses. Itâs all about having fun and if you win in the process, thatâs a bonus. (Sorry about the pun).
Watch Out for Bonus Terms and Conditions
Remember I said at the beginning, itâs the whole deal that has to be considered? Each bonus has its own special T&Cs and if you donât read them carefully before you claim the offer, you might get caught out unawares.
Bonus T&Cs will touch on things like:
- The minimum and maximum amount of money you can withdraw.
- If you land a big win, you might not be able to withdraw all the money.
- They might restrict the games you play.
- They will also specify a wagering requirement and a time in which you need to meet it.
All these restrictions are pretty standard, but if online gambling is going to become a favourite pastime, they wonât matter so much. If you really donât like the bonus T&Cs, skip claiming the bonus, Theyâre not obligatory. But, taking all that into account, bonuses really can extend your bankroll quite considerably.

Where to Look for the Best Bonuses
Youâll find casino bonuses in many places. They get advertised on television, in newspapers, at online casinos, and casino review sites. They are also listed on casino bonus offer coupon sites.
Trustworthiness is the only thing you have to worry about. All of these sites say the offers they list are genuine. Some invariably are not. Thatâs why I always recommend you pick promo codes, including no deposit bonus codes through Crikeyslots. I can personally vouchsafe that theyâre all genuine and pretested, including the 400% casino bonuses when theyâre around.
How Software Providers Fit Into the Casino Bonus Scene
Online casinos offer the bonuses, and they create their own terms and conditions. They donât, however, create the games you can play with a bonus. Thatâs the role of the software provider. They decide on what a slot will be themed, the engines used to power the games, the gameplay, and the features. The games are the same whether you play them via a bonus or not, so your enjoyment is entirely down to the skill and creativity of the software provider.
Live dealer game software providers are producing amazing games these days. They are the closest thing youâll get to a brick-and-mortar casino experience. They are so lifelike, as you can see for yourself if you choose one of the live dealer casinos recommended by Crikeyslots.
Steps to Follow for Claiming a Bonus and Withdrawing Your Winnings
Whenever you see a 400% bonus at Crikeyslots, and it could be launched by one of the new online casinos Crikeyslots recommends, this is how to claim it.
- Click the green âCLAIM BONUSâ
- On the casinoâs bonus offer landing page, youâll see the registration form. Supply the personal details requested. These include your name, address, and date of birth, your email address and your mobile number.
- Youâll also be asked to create a username and password. The exact details may vary slightly from casino to casino.
- Select the currency you want to use and a payment method from the dropdown boxes.
- Enter the amount you want to deposit.
- Click âConfirmâ.
To confirm your new player account, the casino may send a link to your email address of mobile device. If they do, click on it and your account will be confirmed. The whole process usually takes less than a couple of minutes.
To withdraw your winning from the bonus, you must first make certain youâve met all of the bonus offerâs terms and conditions. Assuming you have, follow these next steps to claim your winnings:
- Go to the casinoâs cashier page.
- Select âWithdrawâ.
- Enter the amount you wish to take out.
- Confirm which payment method youâre using. (Ideally, it should be the same one you used to make your deposit)
- Click âConfirmâ.
Online casinos reserve the right to check that you are who you say you are, and when they do you will be asked to provide a photo ID (typically a driving licence or passport) and a recent utility bill to confirm your address.
Player Safety
My goal is to ensure you enjoy the best gambling experiences possible, and this starts with your online safety and security. Itâs why I am so keen for you to only use casinos, whether they are traditional, live dealer, or mobile casinos for convenience, recommended by Crikeyslots. They have all been pre-checked and tested to ensure they are correctly licensed by one of the top licensing agencies such as the Curacao government eGaming authority, the Kahnawake Gaming Commission, the Malta Gambling Authority, or the UK Gambling Commission.
Frequently Asked Questions
