The 100 deposit bonus offers 100% or more on top of your first deposit, e.g. deposit £100 cash funds into the online casino, get a £100 deposit bonus in casino funds, play online casino games with a £200 total balance.
A doubled balance makes sure that you can start playing with more money than just your cash, giving you a better chance at winning big.
100% deposit bonus offers for UK players
What is a 100% deposit bonus? A 100% deposit bonus is a special welcome bonus offer for new online casino players that allows them to play with more money, typically £100’s worth of free casino bonus money.
The benefit here is you get to have ~2x more money to play with at the online casino.
In theory, you should get a better chance at winning big because your chances of making a successful wager increase, but the additional funds are in play money and not actual cash. So this shouldn’t be confused with using real cash that you can withdraw from the online casino.
100% deposit bonus explained
A 100% deposit bonus works typically when the player deposits £100 and gets another £100 in bonus funds, or 100% on their first deposit.
The bonus amount is a 100% match of the players deposited cash amount.
Players can then take their deposited cash funds plus their bonus funds into the online casino games and make bets.
At some online casinos, the welcome deposit bonus is a 100% match of the deposit amount with bonus spins rather than, or in addition to, bonus funds.
Free spins welcome bonuses usually credit at a 100% rate of one free spin for every £1.00 deposited.
Should I play with casino welcome bonuses?
The short answer is yes; you should play with them. However, there are a few things you should know before claiming the bonus funds.
Firstly, please don’t get too excited and look at the casino bonus as a chance to make instant free money because it isn’t, nor is it intended to be used that way. You can not withdraw the deposit bonus funds instantly as cash.
There is a chance that you will lose money when playing online casino games with your welcome deposit bonus funds, so don’t buy in or spend more than you can afford to lose.
The casino bonus welcome offer is there to get new players used to the online casino software and games, familiar with how everything works and hopefully turn them into long term customers.
As there is a chance that you could lose your welcome casino bonus funds, this is part of the deal when taking a welcome deposit bonus, so don’t expect it to become cash funds instantly.
Deposit to get the best UK welcome bonus
Some online casino welcome bonus does not require you to make a cash deposit. However, the biggest and best casino bonuses are welcome bonus deposit bonuses.
Why should I choose a 100% deposit bonus? Here is a list of reasons why the 100% welcome bonus is the best:
- The bonus funds allow you to play more spins or at higher bet amounts
- You can try new games
- You can increase your chance to win big
- Try new casinos and see what’s new
- Experience a different online casino
Bonus funds are separate from cash funds
Now that we know why to choose a 100% match deposit bonus welcome bonus, we need to understand how each deposit bonus differs at each online casino website.
One significant difference is whether the online casino sites keep your bonus funds separate from cash funds.
When a qualifying deposit completes, a first deposit balance is cash plus bonus money.
With an active bonus, the player starts making bets and winnings are paid back to the deposit and bonus money balance, respectively.
At some online casinos, only bonus funds count toward the wagering contribution.
The following online casinos with 100 deposit bonuses take bets from your cash balance first, pay winnings back to the cash balance, and the cash bets do not contribute to the wagering requirements:
- Skol Casino
- 21 Prive Casino
- Hello Casino
- Slotnite Casino
- Casimba Casino
- Dream Vegas
- Jackpot Village
- Grand Ivy Casino
- Sun Vegas
- All British Casino
At this list of 100 deposit bonus casino websites, bets are taken from the cash balance first, winnings paid back to the cash balance, and all bets contribute toward the wagering requirement:
Can I withdraw my bonus winnings as cash?
All of the online casinos in the above lists have forfeitable casino bonuses. Forfeitable casino bonuses mean that you can withdraw cash funds at any time, and unused bonus funds along with the active bonus terms and conditions will disappear.
Is a bigger welcome bonus better than a small one?
Big casino bonuses allow players to play for longer, at bigger bet sizes and with more bonus funds.
For some players, this is better than small casino bonuses.
However, other players may prefer low wagering bonuses.
Low wagering bonuses are easier to complete and cash out. The following online casinos offer no wagering requirements on their free spins welcome bonus. With these welcome bonus offers, the free spins winnings payout to your cash funds balance. They are known as ‘free spins with no wagering’ welcome bonus offers:

What is a better 100 deposit bonus: free spins or a casino bonus?
Choosing a first deposit welcome bonus can often be between free spins or a matched deposit bonus offer.
Which is better depends on the offer and its full T&Cs apply.
The min deposit is likely to be the same, and the max bonus is usually higher with a bonus money deposit bonus.
Some free spins welcome bonuses have no wagering requirements and max bet restrictions, but this benefit is offset by the limited games on which free spins are valid.
First deposit welcome bonus with free spins and bonus exclude more experienced online casino players as the free spins bonus amount is smaller and more limited.
Experienced players who are more comfortable with wagering requirements, max bet, and bonus funds contribute terms, will find that free spins welcome bonuses are less satisfying than a casino bonus deposit bonus.
