Many online casinos don’t use bonus codes anymore for redeeming casino bonuses. However, bonus codes have some positive sides too. When casino bonuses are admitted automatically, you may sometimes get a bonus accidentally, without actually wanting one. With bonus codes, you’ll ensure you’ll get the exact bonus you want. In this article, Casino Professor presents 3 different online casinos, where you can snatch a nice bonus with a bonus code.


10Bet was founded in 2003 and it has a license from Malta. And we love these European casinos, as it means no taxes for European players. The casino is dripping with excitement. This casino definitely won’t leave you hanging, as they offer over 400 casino games and a possibility to bet on sports as well!

10Bet offers a pretty generous bonus for their new players, as they have divided their casino bonus in 4 different deposits.

  1. Deposit: 125% bonus up to 300 euros
  2. Deposit: 125% bonus up to 300 euros
  3. Deposit: 125% bonus up to 300 euros
  4. Deposit: up to 110 euros of cashback after 30 days

The first 3 bonuses are pretty standard and easy to understand. The cashback bonus, however, is something that’s not often seen at casinos. Cashback is a little extra money that the casino pays from your net loss. This bonus gives you 10% cashback of the amount you may have lost in the casino in the 30 days after you created your account. Not bad, eh?
10Bet doesn’t offer any free spins as a casino bonus, but not to worry: they have on-going promos and bonuses often!

Fortunately the wagering requirement is a fairly nice one, as it’s only 25 times. It’s below average, which makes us wipe our forehead and sigh of relief.

And we already mentioned that this casino asks for bonus codes before you get your mitts onto these bonuses. They are as follows:

  1. Deposit: FIRST300
  2. Deposit: SECOND300
  3. Deposit: THIRD300

Write them down!

Guts Casino

Guts has been around since 2013, and despite its name, you don’t need “guts” to join this casino, as they’re very warm and inviting. Guts has a license from Malta and over 850 wonderful games, which definitely will entertain beginners as well as a little more experienced players.

Guts offers a cool, traditional doubling of your deposit on the first deposit and 25 free spins on Starburst. After the very first deposit, you’ll have three more chances to get more bonus money and free spins.

  1. 50% up to 50 euros + 25 free spins on Starburst only
  2. 25% up to 50 euros + 25 free spins on Starburst only
  3. 200% up to 100 euros + 25 free spins on Starburst only

This is a very generous bonus that should not be passed on. If you choose to take an advantage of the maximum bonus, you’ll end up reaping 450 euros worth of bonus money and a bunch of free spins to the most popular casino game ever, Starburst.

Now, as for the bonus terms, let’s start with the good news: free spins are totally wager free! When it comes to bonus money, it must be wagered like this:

  • All bonuses have to be wagered at least 35 times before withdrawal or use in other games
  • Bonuses equal to or above 150% have to be wagered 40 times
  • Bonuses equal to or above 200% have to be wagered 45 times

And remember those bonus codes!

  • First deposit bonus code: GUTSB1
  • Second deposit bonus code: GUTSB2
  • Third deposit bonus code: GUTSB3
  • Fourth deposit bonus code: GUTSB4
