  • Allowed Games: In some cases, you won't be able to play certain titles, but the games that are allowed or restricted will be spelled out for you.

Keep Your Winnings with our Top10 Tips

Taking advantage of these large match bonuses can add a lot of weight to your bankroll, but we want to make sure that you're able to have a great time and keep your winnings. To make this easier for you, we have our list of our top 10 tips below that will help to make things go much more smoothly for you and give you a much better experience.

  1. Look over the game restrictions before you ever claim the offer to make sure that your favorites are allowed.
  2. Consider the validity period of the offer and think over if you'll be able to clear the play-through requirements before it expires.
  3. The highest percentage match isn't always the best fit for you, so look at all of the terms collectively instead to find what's best for you as an individual.
  4. Make sure to use the correct information when signing up so that you don't run into any issues with your account verification.
  5. Don't be afraid to try the demo versions of different games before playing for real money to see if they give the kind of experience you're after.
  6. Using the mobile casino apps for these sites allows you to get in extra wagers here and there while you're out and about to clear the play-through faster.
  7. You'll be asked to verify your account information before you'll be allowed to cash out, and doing so ahead of time right after registration can make your withdrawal come faster.
  8. Some banking methods like credit cards have faster or slower withdrawal times than others, and you can strategically select from them accordingly.
  9. The safest, legit sites are like the ones we review and recommend with full licenses from reputable regulatory jurisdictions.
  10. Some providers like NetEnt offer special bonuses and events on top of what the operator has, and those are worth looking out for to get an extra bit of value.
