How a 100% casino bonus works

If you are looking for a simple yet attractive deal when joining a new online casino, the 100% match bonus on the first deposit might be for you.

Such an offer doubles your first deposit by 100%, allowing you to play with twice the amount you have transferred onto the online casino. Some gambling platforms offer you free spins for specific slot games on top, too.

Some operators set a relatively low limit that they are willing to match, while others are more generous. We made it our goal to find the casinos with the highest 100% match bonuses on this page, giving you a list of licensed operators to make the best pick possible.

This type of offer is a first deposit bonus, so you must be willing to make a payment to take advantage here, and keep in mind that there are various conditions such as wagering requirements and game restrictions.

What you can get 

Aside from having your first deposit doubled, you can also get various other rewards which we will discuss in detail.

Free spins: with those, you can play specific slot games for a few spins free of cost while still being able to win and withdraw your winnings.

Sometimes, the operator will limit how much of your winnings accrued from bonuses you can keep and withdraw, so pay attention to the terms before claiming them.

You could get the game credits for popular titles like Starburst, Book of Dead, or Dead or Alive to try out new and established releases from the most prolific software providers like Netent and Micrograming.

Live game credits: Some will give you free chips or other names, allowing you to place a few free bets on specific live dealer titles.

Cashback: This highly sought-after deal has online casinos giving you back a percentage of your losses, either on a monthly or progress-based basis and allows you to get as much as 15% of your losses reinstated.

The best casinos with 100% match bonus offers

After going through hundreds of websites looking for the best deals, we can say these are some of the best 100% casino bonuses we have found:

  • Spin Rio: 100 % up to £50 + 100 free spins
  • All British Casino: 100% up to £100 + 10% cashback
  • Mr Play 100% up to £50 + 100 free spins
  • Casumo: 100% up to £25 + 25 free spins
  • Pela 100% up to £100 + 200 free spins
  • Casino Joy 100% up to £100 + 200 free spins
  • Genesis Casino: 100% up to £100 + 300 free spins

Most of these online casinos require you to deposit £10,00 to get the bonus money and game credits. You will find typical games like slots, blackjack and roulette on their platforms, or more exotic formats like scratchcards and Slingo. If you’d like to receive an even higher match bonus you can take a look at our list of 200% casino bonuses.

Best Live Casinos with 100% match bonus offers

If you want to replicate the experience of gambling halls, you need casino games with real croupiers that broadcast the action live through the webcam – and a good offer. We have searched to find the best live casino bonuses with a 100% match offer, and here they are:

  • Sloty: 100% up to £100 match bonus
  • Vegas Hero: 100% up to £100 match bonus
  • The Online Casino: 100% up to £100 match bonus
  • Casino Cruise: 100% up to £100 match bonus
  • Mansion Casino: 100% up to £200 match bonus

You will be able to bet on all live dealer games with the bonus funds, including roulette, blackjack and even game shows like Monopoly Live or the Dream Catcher. Also here, turnover requirements and other conditions must be adhered to as otherwise, you will be at risk of losing your funds.

How to claim your 100% casino bonus offer

Online casinos have somewhat strict regulations, requiring players from certain regions such as the United Kingdom to verify their identity before allowing them to add funds and play. We recommend doing that right after registering an account, as that will diminish the chance of experiencing withdrawal complications. 

Aside from that requirement, claiming a 100% match bonus many casinos offer is simple:

  1. Pick a good offer and pay attention to the terms and conditions;
  2. Now visit the online casino’s website and register an account;
  3. Claim the 100% match bonus in the cashier and make a qualifying deposit.
  4. The bonus funds should now be in your account, so you are ready to play.

Keep in mind that there are various restrictions attached to casino offers, including wagering requirements, bet limits, maximum win policies and game restrictions.

Given the abundance of conditions set by the operator, many players look for online casinos without bonuses to avoid being in breach of any of them and consequently at risk of losing their bonus funds and possibly even their deposit.

Tip: if you want to play hassle-free, simply tell the casino that you don’t want any bonus, and they’ll grant you that wish.
