May is almost here and you know the drill. All online gambling sites want to attract new customers and keep the existing ones happy, so they launch all sorts of exciting offers.

I have collected the best online gambling bonuses and promotions for May 2021 in this post. The deals here can help you boost your bankroll significantly if you play your cards smart.

I’ve tried to keep the list balanced, so you can find both bonuses and promotions for online casino games, sports betting, and online poker.

Some of them are for new players, but a good chunk of the promos are open to users that already have an account, so there’s something for everyone. Enjoy!

Let’s begin with some of the best options for new players.

If you’re still searching for the most suitable platform for your needs, you should definitely consider my selection of top welcome bonuses for May 2021.

Here are the most important details about every offer I’ve picked.

I strongly recommend you to check the additional bonus codes too, because many of the sites have special offers for cryptocurrencies or other exciting promotions for May 2021.

Online Casino Game of the Month Promos for May 2021

One of the regular casino promotions I feature in my post on the best gambling offers is the game of the month deal.

It runs every month on certain sites and May is not an exception. You can enjoy various perks and try new games once again at the following casinos.

Las Atlantis Casino Game of the Month – Pulsar

Let’s begin with Las Atlantis that offers a bonus of up to 280% and 20 free spins to try RTG’s slot Pulsar.

The game is not the best by this developer, but it certainly can bring a lot of fun to the table for players who love space.

The theme includes cool planets, exciting animations, and a beautiful background. Here’s what you need to know about the main characteristics of Pulsar.

  • Provider: RTG
  • Reels: 5
  • Paylines: 20
  • Cascading Wins Feature
  • Neutron Stars Feature

The layout is unconventional and you can enjoy some cool side features if you go to Las Atlantis to play Pulsar. The Cascading Wins option can bring you a huge return, while the Neutron Stars add a lot of spice to the game.

Feel free to see for yourself by visiting Las Atlantis Casino.

El Royale Casino Game of the Month – Paddy’s Lucky Forest

One of the most common scenarios with the game of the month promo is that the casinos want to promote new titles. That’s exactly the case with El Royale’s choice for May.

Paddy’s Lucky Forest was launched by RTG in March and is still relatively new to most players. If you want to try it this month, El Royale Casino will give you a 165% bonus and up to 40 free spins.

Here are the main facts about Paddy’s Lucky Forest if you’re not sure if this game is for you.

  • Provider: RTG
  • Reels: 5
  • Paylines: 720
  • Progressive Jackpot
  • Slippery Wild
  • Pick Bonus

The slipper wild and the Pick Bonus triggered by the scatter symbol add enough side features and you could also grab a progressive jackpot playing Paddy’s Lucky Forest.

Obviously, the theme revolves around Irish folklore, so if you love leprechauns, fairies, and pots of gold, you should definitely visit El Royale Casino and try this one.

SportsBetting.ag 20% Weekly Esports Rebate

If you have been following my blogs, you probably know that I love esports. That’s why I want to mention SportsBetting.ag’s 20% weekly esports rebate that’s available in May 2021.

It provides a nice safety net for anyone who has a bad week betting on esports and it’s worth it if you’re going to target this field anyway.

Here are some important details to consider about this SportsBetting.ag gambling promotion.

  • The promo applies to the period from 00:01 am ET on Monday until 23:59 pm ET on Sunday.
  • The minimum loss required to qualify is $250.
  • The maximum rebate is limited to $200.
  • The rebate is credited in $10 increments as bonus funds that you need to rollover 50 times in the casino.

I wouldn’t recommend going out of your way to get this one, but it’s certainly a nice bonus for everyone who bets on esports anyway and SportsBook.ag is one of the best places for that online.

BetUS Blackjack Weekends

Most online casinos don’t offer special blackjack promotions, and some don’t even include the game in their regular deals because of the low house.

BetUS Casino is one of the few exceptions and you can find several blackjack promotions available this month.

The one I like the most is called Blackjack Weekends and it opens the door to one of the best casino bonuses in May 2021.

You can receive a 50% match to your deposits up to $500 with favorable conditions for blackjack. Here are the important terms that come with this promotion.

  • 30x rollover on blackjack games before you can request a payout.
  • Max winnings from the bonus are capped at $2,500.
  • The promo runs from 12 am ET on Saturday to 11:59 pm ET Sunday.
  • The minimum qualifying deposit is $50.

If you love blackjack, you know that you can rarely find such a great offer for this game and BetUS has other exciting options, so feel free to check it out.

Wrap-Up

If you’re planning on gambling online with real money in May, you should most definitely add some bonuses and promotions to the mix to improve your chances to finish the month ahead.

Expect a similar post for June too because the gambling sites often have great deals for the summer season too and I will be on the hunt for the best monthly promotions once again.
