1. Slots.lv – $7,500 Online Casino Welcome Bonus
- Casino sign up bonus package covers 9 deposits
- $5,000 for cash gamblers

Slots.lv spreads the excitement across your first 9 deposits with up to $5,000 for debit card players and a staggering $7,500 for cryptocurrency gamblers.
We consider this to be the best online bonus casino – not only because of its size, but also because the wagering requirement is easy to meet.
Fiat gamblers will score a 200% deposit match bonus worth up to $1,000 following their initial transaction, but this is merely the tip of the iceberg at Slots.lv. Your next eight deposits will be credited with a 100% match up to $500 each.
Meanwhile, Bitcoin bettors can get started with a 300% crypto match up to $1,500. Their reload bonus offers are similarly generous, with each transaction up to your ninth qualifying for a 150% match up to $750.
That means you can get a total of up to $7,500 in sign up bonus casino funds at Slots.lv.
New sign-ups will have 6 months to play their favorite slots, virtual table games, and specialty titles before the clock runs out. Better still, there are no cash out limit restrictions to mention at Slots.lv! If you get lucky, you’ll keep every cent of your real money winnings here.

Cafe Casino gives you all the bonus money you could ever need upfront – just make your first qualifying deposit of $20 via crypto or $25 by debit card to get started. You can use Bitcoin, Bitcoin Cash, Ethereum, Litecoin, and all major credit card brands to claim bonuses here.
You’ll get a 250% online casino registration bonus up to $1,500 or an even sweeter 350% Bitcoin bonus up to $2,500! Both options are generous, but we trust you to make the right decision.
At this big sign up bonus casino, it’s easy to find your niche among 160+ classic slots, jackpot games, and specialty titles. In between spins and rounds, you can explore 7 variants of bingo, keno, and more.
Like our top pick, Cafe Casino gives new sign-ups a full 6 months to satisfy their fair wagering requirements and cash out the difference. There are no withdrawal limitations to mention, which is always a good sign.

Ignition greets seasoned poker players and avid casino traditionalists with their double-ended welcome package! You can use a debit card, Bitcoin, Litecoin, Tether, Ethereum, or Bitcoin Cash to redeem a maximum of $3,000 in casino and poker funds.
Fiat players will score a 100% casino bonus up to $1,000 with their first deposit, and crypto bettors will get their hands on a 150% deposit match bonus up to $1,500. The casino signup bonus is good to play 250+ online slots, 34+ live dealer games, and 8+ video poker variants.
The casino portion of your bonus comes with low 25x wagering requirements. You’ll have 30 days to meet Ignition’s standards and withdraw the difference. Poker players who come back for seconds will receive an identical 100% match up to $1,000 or 150% match up to $1,500.
The poker bonus funds are unlocked at $1 for every 30 Ignition Miles earned in the process of playing poker. These “comp points” stack up very quickly, and you can withdraw any money you’ve already received immediately.

4. Red Dog – 225% Slots Sign Up Bonus up to $12,250
- Five-tiered sign up slots bonus
- 225% deposit match
- Total value $12,250
- Low, $10 deposit minimum
At Red Dog Casino, you’ll play 156+ beginner-friendly games and explore 120+ awesome slots with up to $12,250 in extra funding! This welcome package covers your first five deposits, and each qualifying transaction will receive a 225% bonus up to $2,250.
NeoSurf users can deposit just $10 to claim each portion of Red Dog’s deposit package, but this minimum jumps to $20 for BTC/ETH/USDT bettors and $30 for debit card gamblers. We’d highly suggest using BTC or NeoSurf to claim an extra 20% in bonuses.
Notably, you can play slots, bingo, keno, board games, and scratch cards with an active bonus. The most you can bet per spin or round is $10; and you’ll have to satisfy Red Dog’s wagering requirements for each portion of their five-tiered welcome package.
In practice, new sign-ups will have approximately 3 months to play through Red Dog’s full slot sign up bonus! You’re allowed to withdraw 30x your original deposit at every turn, so it pays to fund your account with more upfront. As it stands, the most you can deposit is $1,000 per transaction.

5. Wild Casino – $5,000 Five-Tiered Casino SignUp Bonus Offer
- Up to $5,000 in sign up bonus casino funds
- Covers your first 5 deposits
- $20 minimum deposit
- Bonus codes “WILD250” & “WILD100”
Wild Casino’s wild deposit package is designed for players who wish to stick around. You can get your hands on up to $5,000 in bonuses with a debit card, money order, bank wire transfer, cashier’s check, Bitcoin, Bitcoin Cash, Ethereum, USDT, Litecoin, and 13 other forms of crypto.
Just use the bonus code “WILD250” with your first cash or crypto deposit to get started. As a new player, you’ll receive a 250% match bonus worth up to $1,000 straightaway.
Then, use the deposit bonus code “WILD100” with your next four transactions of $20 or more. Wild Casino will double each qualifying deposit up to $1,000; leaving you with a potential grand total of $5,000 in casino cash ($9,000 for crypto).
You can play through 200+ slots, enjoy 8+ video poker variants, or finesse the dealer with 11 virtual blackjack tables. Live dealer games are off-limits for now.
New sign-ups will have 30 days to meet Wild Casino’s wagering requirements for each portion of their bonus, which translates to 5 months if you’re going for broke. Still, there’s a final cashout limit of $10,000 or 10x the total deposit bonus amount.

6. Super Slots – 400% Crypto Casino Online Sign Up Bonus up to $4,000
- 400% crypto bonus up to $4,000
- $20 minimum deposit required
- Welcome package up to $6,000 for fiat
If you’re a high roller looking for some serious bonus money upfront, use the promo code “CRYPTO400” with your first crypto deposit of at least $20. You can score this high-limit welcome bonus using BTC, Bitcoin Cash, LTC, USDT, ETH, and 13 other cryptocurrencies!
For starters, you’ll claim a jaw-dropping 400% initial bonus up to $4,000. This is a one-shot deal if we’ve ever seen one! Even if you deposit the bare minimum, you won’t get started with less than $100 in your casino account.
255+ online slots, 12 video poker variants, and 25 virtual blackjack tables are just waiting to be explored. As we’d expect, you can’t play live casino games with a slots welcome bonus applied. Still, there’s plenty of room to flex your extra funding and win big money in their casino library.
Unfortunately, high-percentage and high-limit bonuses often come with high wagering requirements. “CRYPTO400” is no exception – you’ll have a mere 30 days to meet Super Slots’ 48x wagering requirements and withdraw a maximum of $10,000 in real money winnings.
If you have what it takes to succeed, you won’t want to miss out!

With all this out of the way, use the bonus code “LASATLANTIS” with your first five deposits. For each qualifying transaction, you’ll score a 280% deposit match bonus worth up to $2,800. They’re essentially tripling your bankroll upfront, which gives you plenty of room to bet big.
New sign-ups will have 21 days to meet Las Atlantis’ 35x wagering requirements and withdraw a maximum of 30x their original deposit.

It’s worth noting that Mirax’s welcome package is also applicable to fiat players, but the bonus is considerably smaller: up to $1500 in potential cash.
Either way, this leaves you with quite a bit of room to explore. Mirax is home to 2,000+ state-of-the-art real money online slots, and many of them are exclusive to the site!
You can only “win” up to 0.005 BTC from your free spins, but their casino match bonus doesn’t limit your earning potential. So long as you satisfy Mirax’s wagering requirements within 14 days, you’ll keep 100% of the profit.

Online Casino Sign Up Bonus Terms & Conditions
Bonuses and various promotions are what sets online casino sites apart from their brick-and-mortar counterparts. They encourage new players to sign up and make their first deposit by giving them an initial boost with deposit match or free spins.
But, as enticing as they may seem, these bonuses come with specific terms and conditions that you should understand. Let’s go over some of the key terms you should know when selecting the perfect sign up bonus for you.
Minimum Qualifying Deposit
The minimum qualifying deposit refers to the smallest amount you need to deposit to become eligible for the sign up bonus. Online casinos set different minimum limits, so it’s important to check what this amount is.
Deposit Methods for Bonuses
While most online casinos offer a variety of deposit methods, not all are eligible for the sign up bonus. For example, some casinos exclude deposits made through certain e-wallets like Neteller or Skrill from bonus eligibility.
Caps on Winnings
Some online casinos put a cap or limit on the maximum amount you can win using the sign up bonus. It means if you hit a jackpot, there might be a ceiling on the amount of bonus-derived winnings you can withdraw.
Wagering Requirements / Playthrough
Wagering requirements, also known as playthrough requirements, indicate the number of times you must wager the bonus amount before you can withdraw the winnings derived from it.
Game Contributions to Wagering Requirements
Different casino games contribute differently towards meeting the wagering requirements. For example, slots might contribute 100%, meaning every dollar wagered counts towards the playthrough, while table games like real money roulette or blackjack might only contribute 10% or not at all.
Time Limit for Bonuses
Online casino welcome bonuses usually come with a time limit within which you need to use the bonus and meet the wagering requirements.
Game Restrictions with Bonuses
Not all games may be eligible to be played using the sign up bonus. Some games might be entirely excluded, while others might count less towards the wagering requirements.
Bonus Codes in Casino Bonuses
Some casinos require a bonus code to claim the sign up bonus. These codes are either provided by the casino on their promotions page or sent via email. Remember to enter the bonus code at the time of deposit to successfully claim your bonus.
Claiming the Best Online Casino Sign Up Bonus Offers – FAQ
Can I Use My Sign Up Bonus to Play Online Casino Games for Real Money?
Yes, you can play online casino games for real money online. Our top picks are authorized to accept real money wagers from their players.
Still, new sign-ups who need practice can play free casino games before putting down real money.

How Can I Spot A Reputable Online Casino Welcome Bonus?
A reputable online casino welcome bonus is offered by licensed casinos. They offer independently audited games and genuine bonuses. Always ensure to verify these features before claiming a bonus.
For your protection, our team only reviews above-board online casinos. If you choose to deviate from our top picks, always check the bottom of your site’s homepage for a certification or badge.
What is the Best Casino Bonus for New Customers?
Slots.lv offers the best online casino signup bonus for new customers – up to $5,000 cash or $7,500 in Bitcoin across your first 9 deposits.
Depending on your currency preferences, you’ll score a 200% match up to $1,000 or 300% match up to $1,500 off the bat.
Then, you’ll receive a 100% match up to $500 or 150% bonus up to $750 following your next eight qualifying deposits. You’ll only have to part with $20 to get started, and you’ll have a full 6 months to satisfy Slots.lv’s 35x wagering requirements before this welcome package expires.
Which Online Casino Has the Biggest Welcome Bonus?
Mirax has the biggest online casino bonus. They’ll match your initial deposit up to 5 BTC, and the 150 free spins make this deal taste even sweeter.
Bitstarz is a close second to Mirax, but you’ll have the opportunity to score 5 BTC with your first 4 deposits instead of getting all the deposit bonus money upfront.
What Online Casino Gives You Free Money for Signing Up?
All online casinos on our list give you free money for signing up and making a deposit. So, you don’t get free money only for signing up – you also have to meet certain conditions first.
Alternatively, no deposit bonus casinos can offer you a small free chip or free spins to try and win free money after you register, but these offers are not as valuable as the other best welcome bonuses that require a minimum deposit.
How Should I Pick the Right Casino Sign Up Bonus for Me?
Selecting the right casino sign up bonus depends on your budget and preferred casino games. However, for most players, Slots.lv offers a versatile bonus that suits various needs.
Ignition and Red Dog offer a specific focus for seasoned gamers. No matter which deposit bonus you choose, keep wagering requirements in mind. You’ll have to spend or win the amount of your original deposit a certain number of times before cashing out.
