100 Matched Deposit Bonus - What is it?

As earlier mentioned, a 100 deposit bonus is the offer used by UK online casinos to entice new customers. This deposit bonus does exactly what the name suggests. It doubles your first deposit bonus to boost your starting bankroll.

If you're looking to make your first deposit at a new casino, 100% matched deposit bonuses are an attractive option. The good side of it is that it's easy to comprehend how this bonus works. Let's take a look at how this bonus works:

For example, if the casino offers 100% matched deposits up to £300, and you deposit £100, you can claim £100 for free. If you wanted to claim the maximum of the 100% offer, though, you would have had to deposit £300. Right now, one of the most popular welcome offers in the industry is the 100% matched deposit bonus.

Do understand that the 100 bonus funds are often accompanied by free spins bonus. The free spin winnings you get also have wagering requirements to meet, and the spins expire after a while. Casino free spins valid time is usually shorter than the 100 bonus.

Furthermore, you'll learn that free spins winnings and the bonus funds are separate from the cash funds in your account. Many casinos will allow you to spend the bonus money before using the real cash.

Who Can Claim 100 Deposit Bonus Funds?

Contrary to many misconceptions, the 100 bonus offer is available to new and existing players. Even though most online casinos offer them as part of the welcome bonus package, the rules are flexible to allow high rollers and loyal customers. Additionally, this bonus can be claimed by seasoned players as a reload bonus. For instance, you can find live casino bonuses that reward extra money equal to the cash funds you deposit into the account.
