Thunderkick Gaming Expert Review
💬 From the Expert: “While you’ll find more games from other highly-regarded Scandi studios like NetEnt and Play’n GO, the attention to detail in Thunderkick slots is unmatched. In fact, every game in its line-up is unique; you won’t find re-skins and carbon copies from Thunderkick.
“It’s also one of the few studios with a game (1429 Uncharted Seas) with an RTP above 98%, and Thunderkick bonus rounds are much more inventive than standard rinse and repeat free spins rounds with little innovation. Thunderkick is a studio to try if you want to play slots with flair.”

Ways of Athena
Land wins in up to 43,923 ways in this beautifully designed ancient Greek slot and benefit from mystery symbols and free spins to land the biggest prizes.
Our rating: ⭐️⭐️⭐️⭐️⭐️
Slot features:
Return to player: The theoretical return to player in Ways of Athena is 94.21%.
Ways to win: There can be between 243 and 43,923 ways to win in this game.
Matching mystery symbols: Mystery symbols can land on reels 2-5 to form wins.
Free spins bonus: 3+ bonus symbols on the reels award eight free bonus spins.
Max win potential: The maximum win in Ways of Athena is 25,000x the bet.
Though the RTP in Ways of Athena is slightly below the industry average, this is a stunning slot game with a brilliant bonus round. Three or more scatters in view award eight spins, but the game can be retriggered up to 44 spins, letting you play for a 25,000x max prize with the help of special mystery symbols.
1429 Uncharted Seas
Few slots in the world, let alone from Thunderkick, have RTPs over 98%, making 1429 Uncharted Seas’ 98.60% return to player highly impressive and reason enough to play this game.
Our rating: ⭐️⭐️⭐️⭐️☆
Slot features:
Return to player: The theoretical return to player in this slot game is 98.60%.
Low variance gameplay: This slot has low volatility for regular, albeit small, wins
Lines and layout: 1429 Uncharted Seas is played on a 5x3 grid with 25 fixed lines.
The bonus symbol: 3-5 bonus symbols in view award 10 to 50 free spins.
Max win potential: The max payout in 1429 Uncharted Seas is capped at 670x.
1429 Uncharted Seas is a straightforward 5x3, 25 payline slot with a max win of 670x. The bonus round doesn’t come with flashy features or special symbols, but you can unlock up to 50 free spins if five scatters land. As mentioned, the super high RTP, well over the industry average, is the reason alone for giving this sea-faring slot a spin.
Fruit Warp
We love seeing ingenuity in slot design, and Fruit Warp is unlike any other fruit-themed game we’ve ever played, with floating symbols in place of conventional slot lines.
Our rating: ⭐️⭐️⭐️⭐️☆
Slot features:
Unique game layout: Simply find three or more fruits on the screen for a payout.
Portal re-spin feature: Four or more fruits in view grant a portal re-spin.
Fruit mode feature: Five or more fruits award “fruit mode” with multipliers.
Return to player: The theoretical return to player in Fruit Warp is set at 97%.
Max win potential: The max payout via the fruit mode game is 11,000x the bet.
Thunderkick’s innovation is clear for all to see in Fruit Warp, a slot that dispenses with standard reels and rows in favour of floating symbols. If three or more matching symbols float into view, you will bag a win, while four or more matching fruits award re-spins or a fruit mode feature with multipliers that can pay up to 11,000x the bet.
Esqueleto Explosivo
Inspired by Mexico’s Day of the Dead celebrations, this fiery, low-volatility slot from Thunderkick features dropping symbols, a Mucho multiplier, and an explosive wild for more winning chances.
Our rating: ⭐️⭐️⭐️⭐️☆
Slot features:
Lines and layout: This game is played on a 5x3 grid with 17 fixed paylines for wins.
Special dropping symbols: Winning symbols are replaced by new ones from above.
The Mucho multiplier: Each time you win, the Mucho multiplier on the grid increases.
Explosivo wild symbol: This subs for all other symbols & blows 8 surrounding symbols.
Return to player: This game's theoretical return to player percentage is 96.00%.
The Explosivo wild symbol stars in this slot, blowing away surrounding symbols to bring matching symbols onto the grid. The Mucho multiplier is another quirky feature, increasing every time a winning combination lands to help you play for the game’s max prize of 700x the bet.
Milk The Cow
Milk The Cow is a farmyard adventure from Thunderkick with an excellent Hold & Win bonus round where you can play for the 5,000x max prize.
Our rating: ⭐️⭐️⭐️⭐️☆
Slot features:
Cluster pay slot: Receive a payout when five or more symbols land in a cluster.
Wild field feature: Two wild cows activate the field feature to create bigger wins.
Hold & win: Activate the bonus game for three re-spins & a chance to win 5,000x.
Grand jackpot prize: The grand prize is awarded when cows fill all the grid spots.
Return to player: The theoretical return to player in Milk the Cow is 94.17%.
We love Hold & Win slots, and Milk the Cow offers three re-spins with a chance of winning the 5,000x max prize. The base game is also packed with features, including a cow wild that can create an enhanced segment of matching symbols for significant prize potential.

Strategy for Playing Thunderkick Games
While slot outcomes are always based on chance, there are a few practical tips that can help you get the most out of Thunderkick games when playing for real money online.
