What is a 100% casino bonus?

A 100% casino bonus doubles your first deposit—if you deposit $50, you start playing with $100. To claim it, you usually need to register, make the qualifying deposit, and opt in or enter a promo code during checkout. These bonuses often come with a wagering requirement (typically 30x to 40x the bonus), which must be met before any winnings can be withdrawn.

For example, 888 Casino gives new players a 100% bonus up to $200 with a 30x wagering requirement. At Betway, a 100% match up to $250 is tied to your first deposit and applies to slots with full contribution rates.

‼️ This type of bonus gives you twice the playtime and a better chance to explore new games or trigger bonus rounds while keeping your real-money risk low.

Types of 100% casino bonuses

There are many different types of 100% casino bonuses nowadays. Usually, they are offered in the form of welcome or first deposit bonuses, exclusively to new players, but they can also be provided in the form of reload bonuses for loyal, existing players, for example.

100% welcome bonus

A 100% welcome bonus allows you to start with double the amount of funds that you initially deposited at an online casino. Let’s say you deposit $100. With the 100% welcome bonus, your starting balance will be $200. Note that wagering requirements and other bonus terms must be followed before the received bonus funds become withdrawable and that a 100% welcome bonus can be divided over multiple, subsequent deposits.

All casino welcome bonuses

100% Sign Up bonus

A 100% sign up bonus is basically just other wording for a 100% welcome bonus. It does exactly the same, as in that you will receive 100% extra on top of your own initially deposited funds, just for registering or signing up at an online casino. Always make sure you read the bonus terms of this type of casino bonus thoroughly to avoid any unwanted surprises.

100% first deposit bonus

The 100% first deposit bonus provides you with 100% additional funds to play your favorite slots and other casino games with. However, it is only provided on your first deposit and not divided over multiple ones, hence the name ‘’100% first deposit bonus.’’

All first deposit bonuses

100% match bonus

A 100% match bonus can be given to both new and existing players. It means the online casino in question will match the deposited funds by 100%, up to a certain height. Note that this can be a welcome bonus, part of a welcome bonus, sign-up bonus, or a reload bonus.

SlotsSpot's rules for choosing the best 100% casino bonus

There are quite some things to take into account when choosing the best 100% deposit bonuses.

Many 100% casino bonuses come with additional related bonuses, such as a series of free spins, free bets, or continuous reload bonuses.

For instance, JustCasino is giving new players an additional 400 free spins.

Deposit requirements

Most casino bonuses come with deposit requirements. These deposit requirements are often clearly stated on the promotional page or in the text of the bonus offer. Naturally, you would want to claim a casino bonus with low deposit requirements.

Ignition Casino, with its 25x wagering requirement on the up to $6,500 welcome bonus, is a great example of an online casino with flexible wagering requirements.

Withdrawal limits

Some deposit bonuses come with withdrawal limits. Always make sure you know the withdrawal limits of any casino bonus beforehand by reading through the bonus terms thoroughly. This way, you avoid facing any unexpected surprises.

Wagering requirements

Wagering requirements indicate the number of times received bonus funds must be wagered before any winnings derived with them can be withdrawn to your bank account, eWallet, or external crypto wallet. Usually, wagering requirements of casino bonus offers are between 30x and 50x.

Available games

When accepting a 100% deposit bonus, you want to make sure you can use it on a wide selection of games. For this reason, our experts recommend checking the lobby of any online casino you want to register. By doing so, you know exactly what games the casino has on offer and what you can spend your bonus on.

How to get a 100% bonus?

Receiving and claiming a 100% bonus at an online casino if fairly simple. However, it can be a daunting process if you have never done it before.

Step 1: Choose a casino with a 100% bonus

First, start by comparing the best online casinos using our top-ranking tables and in-depth casino reviews. When you have found an online casino that suits your needs that offers a lucrative 100% bonus, click any of the "Play Now" buttons to automatically be redirected to the official website of the corresponding casino.

Step 2: Register at the online casino

Register at the online casino offering the 100% bonus by clicking any of the "Register", "Sign Up", or similar sounding buttons at its official site and providing the required personal details. Additionally, identity verification may take place by requesting you an upload of an identity document, such as your passport, driver’s license, or national ID card during the account registration process.

Step 3: Select a payment method and make a deposit

Once you have a fully registered casino account, you are automatically redirected to the cashier page of the casino, asking you to make a first deposit. Select your preferred payment method and enter the amount you want to deposit. Any bonus will automatically and instantly be credited to your account.

Step 4: Enter bonus code (if required)

Some online casinos utilize a bonus code system, which requires players to input bonus codes in order to receive and claim corresponding bonuses. If you forget to enter a certain bonus code, it is often possible to still claim the bonus by contacting the casino’s customer support before making any wages. Simply ask a support agent to credit your bonus manually, and it will often work like a charm.

Step 5: Activate the bonus and start playing

Once you have made your first deposit, your bonus will automatically be activated and added to your balance. With the bonus added to your account, you can start playing your favorite casino games, such as slots, Roulette, Baccarat, and Blackjack.

Terms and conditions of a 100% casino bonus

The terms and conditions of a 100% casino bonus often determine its value. The most important criteria include:

  • Bet Limit. Most casino bonuses come with maximum betting limits like $3, $5, or $10 per hand, spin, or gameround. Make sure you are always keeping by these set limits as surpassing them might lead to penalties, such as void winnings or bonus removals.

  • Time Limit. Online casino welcome bonuses often come with time limits. They tend to be valid for 7, 14, or 30 days and must be used before the expiry date. We recommend reading the bonus terms of any 100% casino bonus thoroughly before accepting it so that you know beforehand what you can expect and won’t face any unsuspected, unpleasant surprises.

  • Winning Limit. Some online casino bonuses come with winning limits, meaning that you are only able to withdraw winnings up to a certain amount. Again, check the bonus terms of any 100% casino bonus thoroughly to avoid accepting bonuses with low max win caps.

  • Available Games. Naturally, you want to be able to play your most favorite online slots and other casino games with the bonus funds you receive by accepting a 100% casino bonus. Always double-check the lobby of the online casino in question to see whether it featured your most-liked casino game(s) and softwaren provider(s).

  • Game Weighting Percentages. Often, bets placed on slots count in full, whilst wagers placed on table and live casino games, such as Roulette, Blackjack, and Baccarat, only count for 10 to 20%.

  • Wagering Requirements. Wagering requirements of casino bonuses indicate how many times received bonus funds need to be wagered before any winnings can be withdrawn from the account. Usually, the wagering requirements of a 100% casino bonus vary between 25x and 40x, with some casinos having higher or lower wagering requirements for their bonuses.

Payment methods to get a 100% casino bonus 💳

The best online casinos accept a wide variety of payment methods, including but not limited to credit and debit cards like Visa and MasterCard, eWallets like Neteller, PayPal, and Skrill, and cryptocurrencies, such as Bitcoin, Litecoin, and Ethereum.

Deposits should arrive instantly into your casino account, without any delays.

‼️ Any 100% casino bonus should also be automatically credited to your balance.

If this isn’t the case for any reason, our experts recommend contacting the casino’s customer support immediately, as they are often able to manually add any bonuses and check into this type of enquiries.

Advantages and disadvantages of a 100% casino bonus

Although 100% casino bonuses allow you to play online slots and other casino games with more funds, they also come with some disadvantages. In some cases, it is even better to not accept a certain offered casino bonus.

Advantages

Being able to play with double your deposited funds.

Being able to wager more per bet than you usually would because of the bonus funds.

Being able to play multiple games as your budget stretches longer.

Disadvantages

Often comes with wagering requirements and other bonus terms.

Can ‘’freeze’’ your own deposited funds until the wagering requirements and other bonus terms are met.

Casino games that are suitable for playing with a 100% bonus

Online casinos often feature thousands of slots, table games, and live dealer games nowadays. Because of this, you are literally spoilt for choice when it comes to games that are suitable for playing with a 100% bonus.

Online slots

Online slots are by far the most popular casino game type at every online casino or gambling platform. Added to this, wagers made on slots often count in full for any wagering requirements attached to the bonus in contrary to table and live casino games. Naturally, this makes them ideal to play with a 100% bonus.

Some of the most popular slots currently played are Gates of Olympus, Book of Dead, and Reactoonz.

Roulette

Roulette is without a doubt the most popular game across online casinos. The classic casino table game can be played in both live and First Person formats, with top titles including Lightning Roulette, Red Door Roulette, and Immersive Roulette, all by Evolution Gaming, the global market leader in live casino software.

Baccarat

Online Baccarat has evolved rapidly over the years. From simple Punto Banco to Squeeze Baccarat with its unique peeking mechanics and all sorts of live variants, presented enthusiastically by real, professional human dealers and game hosts. Current top Baccarat titles include Golden Wealth Baccarat and Prosperity Tree Baccarat, both by Evolution.

Blackjack

Blackjack is the most popular casino card game. At online casinos, you can play all kinds of Blackjack variants, such as ONE Blackjack, Lightning Blackjack, and Party Blackjack. Although some rules differ, the general goal of the game stays the same: reaching a hand value of as close to 21 as possible, without going ‘’bust.’’

Step-by-step guide to withdrawing 100% bonus winnings

Once you have fully met the wagering requirements of a 100% casino bonus, you are able to submit a withdrawal request. In most cases, this is done quite simply by navigating to the "Cashier" page, selecting your preferred withdrawal method and entering the amount you want to withdraw from your online casino balance. After that, simply follow the on-screen instructions to withdraw your casino winnings.

Note! At many online casinos, your account needs to be fully verified in order to withdraw any winnings derived from a 100% casino bonus.

Although the account verification process differs slightly from one casino to another, some common steps apply. You will likely need to upload an identity document, such as your driver’s license, passport, or national ID card. In addition, you’ll be asked to provide a "Proof of Address" — typically a utility bill, rental agreement, or bank statement that’s no older than 3 months. These documents are required to verify your casino account.

Tips to maximize winnings with 100% casino bonus

Many online casino players wonder how they can maximize their winnings with a 100% casino bonus. Here are 4 practical tips to help you with this:

👉 Tip 1: Check the Bonus Terms

Our experts recommend to always thoroughly check the bonus terms before accepting any 100% casino bonus. Criteria like the wagering requirements, maximum bet size, and maximum winnings are the most important aspects of any casino bonus apart from its height.

👉 Tip 2: Choosing the Right Bet Size

Make sure your bank roll or playing budget is sufficient for a decent amount of hands, gamerounds, or spins. For slots, our experts suggest a budget of at least 100x your current bet per spin so that you withstand losing streaks.

👉 Tip 3: Play low-volatility slots only

In most cases, wagers on slots count in full for playing through wagering requirements of any 100% casino bonus. Slots with a low volatility pay out relatively often. You can use this consistent stream of small wins to fund the wagering requirements. Slots like NetEnt’s Starburst and Reel King by Novomatic are excellent examples.

👉 Tip 4: Set a budget and session time limit

Before playing away your 100% casino bonus nilly willy, it is wise to set a clear playing budget for yourself as well as a session time limit. By doing this, you set clear goals for yourself and keep online gambling as a hobby that might make you some money.

Alternative bonuses

Apart from 100% casino bonus offers, there are also alternative bonuses that provide value for players in different ways.

200% casino bonus

A 200% casino bonus triples your own deposited funds up to a certain height. In most cases, it provides you with the same or more funds a 100% casino bonus will provide you, but with more strict wagering requirements.

Popular online casinos handing out a 200% casino bonus at the moment are Royal Ace, with its 200% up to $4,000 bonus and Slots.lv, with its 200% up to $3,000 + 30 free spins welcome bonus.

All 200% casino bonus offers

$100 no deposit

A $100 no deposit bonus allows you to play online slots for real money, without wagering any of your own deposited funds. Although a $100 no deposit bonus provides you with $100 of free money to play with, a 100% deposit bonus may provide you with even more casino playing funds.

Although there are no online casinos at the moment that provide a $100 no deposit bonus to newly registered players, JackBit and RickyCasino both provide up to $100 in free, no deposit bonuses.

All $100 no deposit bonus codes

300% casino bonus

A 300% deposit bonus allows you to receive four times as much casino starting balance as you would without one by quadrupling your initial deposit up to a certain height. For instance, a 300% deposit bonus up to $500 makes a $100 deposit $400.

Note that although a 300% casino bonus sounds in all ways better than a 100% one, this is not always the case, as its wagering requirements are probably higher than the ones that come with the 100% casino bonus.

Currently, Vegas Online Casino and SlotsandCasino both have 300% casino bonuses for new players. With Vegas Online Casino offering 300% up to $3,000 and SlotsandCasino 300% up to $1,500 + 100 free spins, respectively.

All 300% casino bonus offers

100 free spins no deposit

Instead of a 100% casino bonus on top of your deposit, you can also go for a 100 free spins no deposit bonus. This allows you to play a certain new or popular online slot for free whilst having the chance to win real money.

The free spins are offered without a deposit required whilst 100% casino bonus offers require at least one own deposit. Currently, both CasinoDays and Magical Spin Casino give away 100 free spins to new players.

FAQs

1.

The industry-standard wagering requirements for most 100% frist deposit bonus offers are between 30 and 40 times the received bonus funds plus own player deposit. Wagering requirements of 50x and upwards are considered ‘’high’’, while wagering requirements of 25x and lower are considered having relatively low playthrough requirements.

2.

Some 100% casino bonus offers come with maximum withdrawal limits. For this reason, our experts always advize to read the bonus terms of any online casino 100 deposit bonus thoroughly. Naturally, we recommend signing up for a 100% casino bonus that matches the amount you want to deposit the closest.

3.

In most cases, 100% casino deposit offers have minimum deposit requirements and maximum deposit benefits. An online casino 100% bonus of 100% up to $500, for instance, will provide you with $100 up to $500 on top of your own deposited funds. However, if you decide to deposit $750, your starting balance will be $1,250 instead of $1,500 because the 100 sign up bonus casino was capped at $500 (consisting of $750 own deposited funds +$500 bonus funds).

4.

In most cases, online casinos hand out reload bonuses to loyal, existing players. As these reload bonuses can be 100% or more, it is possible to receive a 100% casino bonus while already being a casino player.
