What are 100% Casino Bonuses?

What are 100% Casino Bonuses

100% deposit casino bonsuses belong to the wider category of welcome casino bonuses aimed at new UK players. They often feature a fixed deposit match percentage that rewards the player a certain amount of money depending on their payment.

The 100 deposit bonus is one of the most common offers that doubles the player’s bankroll once they make their first deposit with an eligible payment method.

What Aspects Make a 100% Deposit Bonus Good for You?

Ionut Marin, renowned for his expertise in bonus evaluations, spearheaded the KingCasinoBonus analysis of 100% deposit welcome bonuses for the UK market. Over a period of 30 hours, Ionut and the rest of our team rigorously assessed the terms, focusing on bonus amounts, lower than 40x wagering requirements, and the fewest game restrictions.

The 100 welcome bonus can benefit all players because of the low minimum deposit requirements. Ionut’s personal insight highlights how these top-rated 100% bonus casinos can significantly enhance your initial bankroll for cheap.

This allows low-stakes players to deposit a smaller amount of money and still use the benefits of the bonus. Additionally, these offers can accept higher sums for your first deposit, or they don’t feature a maximum deposit limit at all, making them attractive for high rollers.

In terms of wagering requirements, this subtype of online casino bonus usually sticks to industry standards. This means you’ll be able to find 100% deposit bonuses with 30-40x requested rollover, which is relatively easy to complete. Generally, the terms of higher match percentage bonuses like the 400% deposit bonus are more restrictive.

British gamblers can also access no wagering online casino bonuses that do not have such conditions placed on the bonus usage. Alternatively, our low wagering bonus list features offers with up to 20x playthrough, and quite a number of bonuses with 1x-10x wager.

888casino: Best 100% Deposit Bonus Casino Overall

Best 100% Deposit Bonus Casino Overall 888casino

All new players at 888casino are eligible for a 100% deposit bonus of up to £100, which prompts us to consider 888 as a contender for our top-rated 100% bonus. Claim your bonus in up to 48 hours after registering on the site, and you can use the awarded funds on selected slots, jackpots and live casino games.

Bonus Details

You can claim the bonus with a £20 minimum deposit upon registration and double your funds. There is a 30x wagering requirement on the promo, and you must complete it in 90 days. The maximum allowed deposit is £100, and bonus winnings are capped at £500.

Pros & Cons


  • Considerable bonus amount up to £100
  • Low wagering requirements
  • A vast selection of eligible games, including slots and live dealer titles
  • The maximum win amount is higher than industry standards
  • Long validity period


  • No free spins or free chips are available
  • Deposits with Skrill or Neteller are not eligible for the offer

Our Verdict

Given the long validity period of 90 days and the small wagering requirements of 30x, this offer is perfectly tailored for inexperienced bettors who are testing the gambling waters. Additionally, with low investment, you stand to win up to £500 maximum award!

The downside of the offer is that Skrill and Neteller users will have to pick another payment option to qualify for the bonus. As alternatives for these e-wallet users, we we come forth with our curated Skrill casino bonus codes and Neteller casino list.

Barz Casino: Best New Casino with a 100% Match Bonus

Best New Casino with a 100% Match Bonus Barz Casino

Barz Casino is a professionally operated casino in the iGaming industry that offers new players a 100% bonus match of up to £500 for their first deposit plus 50 free spins. The offer is part of a welcome package featuring bonus funds and free spins for your second and third deposits.

Bonus Details

The wagering requirements for the bonus is 20x, which is pretty favourable for new players considering that the industry standard for playthrough requirements is twice as much. The minimum deposit is also fair, being set at £20.

The bonus cash can be used on multiple games, while the spins are only eligible for the Book of Dead slot, thus also qualifying as a worthwhile Book of Dead free spins  bonus in the UK.

Pros & Cons


  • Very low wagering requirements
  • Affordable minimum deposit limit for low-stake players
  • Maximum reward up to £500
  • Additional 50 Bonus Spins


The spins are only available for the Book of Dead slot.

Our Verdict

As a welcome offer, this bonus can benefit new plates with limited or no experience at all in the casino industry. They get to double their funds and get bonus cash with a low deposit of £20 while also claiming 50 spins to play on Book of Dead.

Additionally, the favourable wagering requirements allow players to win and withdraw possible winnings easily.

Yet, if you consider Barz has a too high minimum deposit, you might want to check out other new online UK casinos we selected for our UK players because, for example, Pub Casino promotions are really worth the low wagering requirement.

LeoVegas Casino: Best Mobile Casino with a 100% Welcome Bonus

Best Mobile Casino with a 100% Welcome Bonus LeoVegas Casino

Register at LeoVegas Casino and claim a 100% deposit match up to £50 plus £6 in chips. The welcome offer is available on both desktop and mobile and can be used at the live casino.

Bonus Details

The bonus wagering requirements are set at 40x, and the minimum qualifying deposit is £10. All live dealer games contribute 100% towards the bonus wagering, qualifying this offer to our live casino bonus list, while slots, table games, and Slingo don’t contribute at all, which is a peculiar situation.

The cash bonus is valid 7 days after claiming, while the free chips expire after 3 days.

Pros & Cons


  • Accessible minimum deposit
  • Reasonable rollover
  • Legal operator with fair games
  • Live casino bonuses are hard to come by.
  • Extra free chips worth £6


  • The maximum bonus reward is relatively small
  • The free chips have a small validity period

Our Verdict

This bonus is great for live dealer games enthusiasts who want to experience the real casino atmosphere from the comfort of their homes. The low minimum deposit of £10 makes this bonus affordable to everyone. Additionally, the casino has a rich live games portfolio.

All games are accessible through a dedicated app, making LeoVegas better than most new mobile casinos in this respect.

How We Researched For Our 100% Bonus List

How We Researched For Our 100% Bonus List

We aim to provide the best casino 100 bonus offers, so we do a complete background check of the casino, its licences and other regulatory bodies that regulate its gaming operations.

Once we ensure the operator is legal, we continue to check the bonus terms and conditions. For our recommendations, we stuck to offers that feature a higher range of allowed deposit and wagering requirements that fall under the industry standards of 40x.

Next is game eligibility. Our expert team manually tested the games on multiple Android and iOS devices, ensuring quality gameplay with no glitches or interruptions. Additionally, we made sure the bonuses feature several allowed games, so players have more choices where to spend it.

At last, our team researched the banking section and the efficiency of the customer support. We made sure you can claim our recommended bonuses with various payment methods, and the casinos that offer them have professional support agents ready to assist if any issues arise.

Games Playable with 100% Bonuses

A 100 deposit bonus UK will often be available as a slots bonus only. However, many operators decide to diversify their offers and include other types of games in the promotion, as exemplified by LeoVegas’ offer just presented.

Game Types That You Can Play on Casino with 100% Bonus


As a general rule, slots contribute 100% towards the wagering of these offers. Some 100% bonus deals are only eligible for slots, while others may allow you to play different categories of games with a lower contribution towards the rollover.

Bzeebet releases 100% deposit bonuses to promote new games, and the reward can be used only on that particular slot. However, most bonuses of this kind have at least multiple slot options for players to explore and bet on.


Scratchcards are often considered a side game at casinos, however, many prominent operators feature them in their game libraries. The 100 casino bonuses for scratch cards are not as popular as those for slots; you can often find them at bingo casino sites.

You can find 100% bonuses where scratchcards contribute up to 100% to the rollover; however, the wagering contribution can change depending on the casino’s policy.

Live Casino

Regular 100% casino bonuses primarily aimed at slot games can allow you to play live casino games as well, but with a smaller contribution. In those cases, the live dealer games contribute only 5-20% to the wagering.

Pink Casino has 100% deposit bonuses specifically aimed at live titles. You can play a selected number of roulette, blackjack, baccarat or poker variations and the maximum bet limit averages £20.

  • Some casinos feature a phone verification process, where you’ll have to contact a support agent to activate your account.
  • In some cases, the casino may require you to wager your qualifying deposit for the 100% bonus before you’re allowed to claim the offer.
  • Certain payment options may not qualify for the bonus, so check the promo’s terms and conditions for suitable banking methods. Some casinos also perform KYC checks for AML compliance.
  • Additionally, some 100% welcome bonus deals can feature a promo code or a coupon you need to enter to claim the perks. You must submit the code upon registration or making the deposit or separately text it to the customer support agent via live chat. The codes are usually available on the promo page in the bonus descriptions.
