    1 Bet Welcome Bonus

    New players at 1 Bet Casino can take advantage of several rewards, but the welcome bonus quite rightly attracts the most attention. At 1 Bet, rookies can claim a 100℅ deposit of up to 500 EUR. To qualify, newbies must enter the code 1BWEL500 and deposit a minimum of 20 euros. As with most welcome deals, wagering terms are attached. At 1 Bet, these ask participants to bet their bonus and deposit 30x before a withdrawal can be actioned.

    Terms and Conditions

    The first thing that you should always look at when you consider the worth of a welcome bonus is the wagering requirements. If these are low, there is more chance that you will be able to convert bonus credits into real cash. At 1 Bet, the requirement for new players to wager both their deposit and their bonus 30x is a little higher than the industry average, but this still gives players the chance to pick up a lucrative return. Other factors to consider include:
    • New players must make a first-time deposit of 20 euros or more to qualify for the welcome bonus.
    • The bonus code 1BWEL500 must be entered to qualify.

    High Roller Casino Welcome Bonus

    Every Highroller Casino knows one of the best ways to keep a demanding clientele happy is to cross its palm with several stellar rewards. On this website, the welcome bonus is the quickest way for new players to pick up an easy bank boost. By depositing a minimum of 20 EUR, newbies can claim a 100% matched bonus of up to 500 EUR and 200 free spins on a range of superior slot games. To take full advantage, you’ll need to be across the terms and conditions of this offer. Among other things, these include a requirement to wager bonus win 40x and free spins win x30 before you can claim a payout.

    Terms and Conditions

    If there is one aspect of the Highroller Casino welcome bonus that most players will take away, it is the opportunity to try out a fine spread of slot games before you ever have to risk your own cash. The 200 free spins awarded alongside the maximum 500 EUR bonus are released at a rate of 20 spins a day, with a different game being the focus on each. Games to try out include:

    21 Casino Welcome Bonus – Free Spins Plus 121% Matched Deposit up to €300

    New customers at 21 Casino can enjoy a lovely 21 free spins and 121% matched deposit bonus when joining. Free spins must be played on Book of Dead; there’s a minimum deposit of €10 to redeem this opening offer. Deposits via Skrill and Neteller aren’t eligible for this deal. This is a lovely opening offer. It’s not as big as some out there, but all that glitters isn’t always golden. Many big opening offers require the bonus and deposit to be wagered a certain number of times. At 21 Casino, you will just need to wager the bonus money 35x before you withdraw. In an industry where the average is 40x, that represents good value. As always, with opening offers, there are some terms and conditions you will need to abide by. We’ve listed the main ones below, but it’s always worthwhile taking the time to read them yourself.

    Terms and Conditions

    • New Players Only, 18+
    • Free spins on Book of Dead
    • Free spins have a 10-day expiry
    • Free spin wins capped at €100

    Welcome Bonus - 100% Bonus up to €6,000 Plus 100 Free Spins

    There are only two words to describe ZotaBet's opening offer - ABSOLUTELY MASSIVE! Their bid to attract new customers sees them offering a phenomenal matched deposit bonus of €6,000 plus 100 free spins. You'd be hard-pushed to find a bigger opening offer anywhere else. So, how does it work? You simply have to deposit anywhere between €20 and €6,000, and they will match it. Of course, there are some terms and conditions you will need to abide by. The main one is that the bonus awarded (and any wins from free spins) will need to be wagered x40 before you can withdraw any winnings. This is bang on average in terms of wagering, so spin away! This is one heck of an opening offer.

    Terms & Conditions

    • New players only

    If you love free spins as part of your opening offer when joining a casino, then Mr Pacho is for you! This fantastic matched-deposit bonus of 100% up to €500 is complemented by a huge number of free spins. You'll receive them at a rate of 20 per day for ten days. The minimum deposit to redeem this Welcome Bonus is €20. To claim, simply make your deposit and activate the bonus in the "Profile" section of the website. Once claimed, you will need to wager/play through the bonus and deposit x35 before you can withdraw any winnings. Any wins from free spins will need to be wagered x40 before you can turn a profit.

    Winawin Welcome Bonus – A Matched Deposit Bonus of up to €4,550 PLUS 1,800 Free Spins

    Winawin says a big Irish ‘hello’ or rather ‘Dia dhuit’ to new players with a thunderous opening offer. New players can claim a matched deposit offer of up to €4,250 PLUS 1,800 Free Spins. This offer is insane! Rarely do we come across opening offers this big when reviewing online casinos. The opening offer is split across your first four deposits. Here’s how it works:
    • First deposit – 100% matched up to €500 plus 100 free spins. Bonus code WIN100.
    • Second deposit – 50% matched up to €1,000 plus 50 free spins.Bonus code WIN50.
    • Third deposit – 75% up to €750 plus 50 free spins. Bonus code WIN75.
    • Fourth deposit – 25% up to €2,000 plus 100 free spins. Bonus code WIN25.
    Clearly, if you want to max out this offer, then you’ll need to put a lot more money in by the fourth deposit, €8,000, in fact. However, just because the upper limit is so high doesn’t mean you need to burst the bank. The minimum deposit for each of the four deposits is set at just €20. This offer comes with a wagering requirement for the bonus amount and any winnings free spins of 50x.

    Terms and Conditions

    • New players only
    • 18+ years old
    • 50x wagering each bonus
    • 50x wagering winnings on free spins
    • You will need to use the bonus code to redeem
    • Free spins expiry is three days
    • Free spins only available on Elvis Frog in Vegas

About Thunderkick

about thunderkickinfo
Number of Games50+
ProductsVideo Slots
HeadquartersStockholm, Sweden

Thunderkick is a Swedish gaming company created in 2012. Their goal? To stay true to themselves, have some fun and “give a damn” about their games and customers.

Those original founding fathers may be in their 60s now but as their website points out, this approach still gives them the “freedom to find their own solutions”.

All of their games are developed in-house, not farmed out to third-party studios like other slot providers. And they certainly evoke the Swedish, clean, crisp and quirky design craftsmanship, with the same unfussy functional use, which made IKEA a household name.

And that desire to keep everything under one roof has left an unmistakable DNA. Once you’ve played a few of their games, they are instantly recognisable.

Neither do they get sidetracked into other avenues of opportunity! Thunderkick is all about the slots; you won’t find table games on their to-do list or Live Casino.

Award Winners

They may be a relative newbie to the iGaming market – a decade isn’t that old – but that hasn’t stopped this company’s unique outlook on slot life from being recognised.

  • In 2020 they had three nominations at Slot Catalog Awards. 
  • In 2019 they won Best New Slot Game of the Year for Midas Golden Touch.
  • In 2017 they were awarded Best Low Volatility Game of the Year for Frog Crog.
  • In 2017 they picked up the Best Mobile Game of the Year award for Flame Buster.

Thunderkick has licences from two of the best in the business, with licences from the UK Gambling Commission and the Malta Gaming Authority. Their games are also tested by QUINEL – one of the world’s leading iGaming test laboratories.

You can certainly chill, knowing this company is legit and safe.

Features & Game Types

Thunderstruck games are highly creative, and extremely well designed with, more often than not, a humorous twist on standard themes.

They average around five new games each year. Like all smaller, more boutique studios, they’re not churning out a conveyor belt of slots for the market.

This focus on quality over quantity means they have more time to fine-tune and finesse, leading to an altogether more well-put-together game. That focus on well-designed slots with great, if at times unusual, gameplay does come at a cost because you won’t find progressive slots at this game provider.

Features of a Thunderkick game include: 

  • Quality design
  • Animations 
  • Wilds 
  • High RTP
  • Good bonus games
  • Expanding symbols.

Highest Return to Player Slots

Thunderkick has a reputation for high Return To Player percentages. So, if you like your payouts quick and pacey, this slot provider is for you. Here are some of their higher RTP offerings.

  • 1429 Uncharted Seas – RTP 98.5%
  • Toki Time – RTP 97.1%
  • Fruit Warp – RTP 97%

Our Top 5 Picks

  • Bork the Berzerker Hack n Slash Edition – Hackinly good blood-spilling fun is the only way to describe this game as Bork tries to Hack n Slash his way to finding the woman he loves. What you’ll really wish to witness in this game, however, is the screen turning into a fireball of a big win. Bork himself is represented as an expanding wild. In the base game, he only ever appears on the third reel. It’s the bonus round where Bork hits the big time. Three bonuses get you on the board, where you get ten free spins; more bonuses than three mean more free spins. Plus, you might get to see Bork on reels two and four as well as three. With an RTP of 97.34% and a max win of 2,100x stake, this is a game not to be missed.
  • Fruit Warp – How do you explain Fruit Warp? Imagine Captain Kirk was sitting in his Captain’s chair with a bowl of fruit, and the Starship Enterprise dropped from Warp 9 to zero in an instant. Those fruit tumbling through thin air in fast then slow motion is somewhere close to describing this truly bonkers game. There are nine reels – but you can’t see them! You win when combinations of three of the same types of fruit are formed with different fruit having different worth. This is a medium variance game with an RTP of 97% and a max win of 216x stake. There are no bonus rounds and no wilds. It’s hard to explain; you need to play it to not understand it. If you’re waiting for the kicker, here it is; the max win can be 11,000x your stake. Wowzers!
  • Toki Time – This fairytale land is full of animated characters gathered together for a spot of fun. These cute characters are shot up in the air at gale force speed from underground tubes to form a five-reel, three-row slot with an RTP of 97.1% and a max win of 1,130x stake. There are some fantastic, nuanced animations on this slot, especially on the faces of the little critters. The main feature of this game is expanding wilds on reels two and four, and if you win, they stick. They carry on sticking as long as you win. Meaning you can clock up some big sums very quickly.
  • 1429 Uncharted Seas – This nautical–themed slot sees an old-fashioned sea map with mythical creatures as symbols filling the screen. It has a top prize multiplier of 670x and one of the highest RTPs on Thunderkick’s books. Following a standard five-reel, three-row format, the ships are wilds but only appear on reels two, three and four; when it does appear, it expands across all three rows. Three scatter symbols win you ten free spins; four win you 20, and five lands you a massive 50 free spins.
  • Spectra – This futuristic-looking slot takes a lot of the symbols from classic slot machines, such as cherries, but elevates them to a whole new level. The style on this slot shouts 1980s revamp, and it couldn’t look any cooler. If you love the original Tron film, you’ll really like this game because that’s the design vibe for this slot. It has five reels, four rows and 30 paylines. You win money by landing identical symbols on any of the pay lines. A colourful W acts as the wild, appearing on reel four. Sometimes it expands; sometimes, it doesn’t. If it does expand, it triggers a respin, with the stack of wilds moving to the left reel with every win – increasing your chances of a payout.

Our View

Known for their quirky, humorous and stylish take on video slots, Thunderkick is, in our humble opinion, kick-ass!

This slot provider is the Fast and Furious of the iGaming world, perfectly engineering highly impactful, nitrogen-fuelled, supercharged slots. To put it simply, they’re head turners.

We love the new twist on old classic themes; we love their graphics and their storytelling, and we love their quirky gameplay.

Most importantly, we love their unerring approach to slot-making. They do it because they are passionate about it, and you can feel that passion with every spin you take.

They are utterly unique! Why? Because Thunderkick makes it about the game first and the slot second.
