How to Claim the Monster Casino Welcome Bonus

The Monster Casino welcome bonus is really simple to claim, but you will need to follow the steps below carefully to ensure you don’t miss out:

  • Join the Casino

    Open the casino on your device and select the Join Now button to begin the sign-up process. Provide your full details, including your name, contact information and date of birth. Ensure your account is verified before moving to the next step.

    First page of the Monster Casino registration process

  • Make Your First Deposit

    Your first deposit at Monster Casino will unlock 100 bonus spins on Starburst. Ensure you deposit at least Β£50 and that you don’t use either Skrill or Neteller to qualify.

    Monster Casino deposit page

  • Make Your Second, Third, Fourth and Fifth Deposits

    Your second and third deposits will be matched 25% up to Β£200, so you’ll need to deposit Β£400 each time to claim the full bonus value. Your fourth deposit is matched 25% up to Β£600, so a deposit of Β£2,400 will claim the full bonus. Finally, your fifth deposit unlocks 50 bonus spins on Starburst.

Welcome Bonus Ts&Cs

Before you try to claim the Monster Casino welcome bonus, you should go over all the terms and conditions. Ensure you understand them, as failing to follow them correctly could mean you miss out on value from this offer.

Here are the main terms and conditions you should be aware of:

  • Deposit method: Deposits made using Neteller or Skrill won’t qualify for any stage of this welcome bonus. Make sure you pick any other payment method but these.
  • Minimum deposit: A minimum deposit of at least Β£50 is required to unlock each stage of the bonus.
  • Deposit match: Your second, third and fourth deposits will all be matched 25%. So if you’d like to claim the full value of the bonus, you’ll need to deposit 4x the maximum bonus amount.
  • Wagering requirements: The bonus, along with winnings you make from the bonus spins, need to be wagered 10x. Not all games will contribute equally to the wagering requirements, and requesting a withdrawal before they’re completed will cause you to lose the bonus.
  • Time limit: You’ll have seven days to use your bonus spins and complete the wagering requirements after claiming. Meanwhile, any deposit bonuses will be active for 30 days before they expire.
  • Maximum conversion: After completing the wagering requirements, your remaining bonus will be converted into real cash, although this is limited to the maximum conversion amount. For the bonus spins, this is Β£20, while the maximum for the matched deposit bonus is Β£50.

Regular Promotions at Monster Casino

The welcome package isn’t the only offer at Monster Casino. There are loads of rewards waiting for you to claim, including more bonus spins, reload bonuses, leaderboards and much more. These can be found on the promotions page, along with the full terms and conditions.
