About Thundercats: Reels of Thundera Slot

It’s a flashback to the 80s in the Thundercats: Reels of Thundera slot featuring a cast of your favourite characters from the original cartoon to give you a suitable bout of nostalgia. The game was developed by one of the biggest names in the online slots world, Blueprint Gaming, whose name you will recognise if you’ve played any of the big titles here at Legs Eleven including another throwback game jam-packed with bonus features, Worms Reloaded which sees players taking part in some annelid warfare in search of potential winning spins!

Thundercats: Reels of Thundera slot is designed to replicate the much-loved design of the TV series and boasts some fantastic graphics as you land on the molten surface of the planet Thundera, home to the famous Thundercats whose travels have brought them back to their home planet to investigate the presence of a slot reel. As you spin through the metallic reels you’ll see some familiar iconography as the logo, the Sword of Omens, Spaceboards, and lots more accompany the more traditional card values ranging from J to A, in ascending order of value. The most valuable symbol on the reels is the Thundercats logo, rewarding lucky players with 50x their stake if 5 are found across a winline; this also appears super stacked on the reels to give you gameplay that is potentially even more rewarding! There is a Wild to help you on your quest through Thundera, and it substitutes for all symbols except for the Scatter, paying out up to 50x for 5 across a winline.

There are bonus features galore to uncover across the lava wasteland that is Thundera, including a randomly triggered Eye of Thundera bonus, which you could awaken during any spin! This will itself trigger 1 of 6 modifiers, including mystery symbols, random Scatters, Wilds, and much more! The gameplay is diverse and varied, making each spin as exciting as the last with the potential to trigger a feature and land up to the maximum win of 10,000x your original stake!

Thundercats: Reels of Thundera Slot Bonus Features

Eye of Thundera

Awaken the omnipotent and omniscient Eye of Thundera by randomly triggering it during a spin and it will summon 1 of the following 6 modifiers to give you another chance to score a win!


The fierce leader of the Thundercats, Lion-O, casts mighty Wilds onto the reels to boost your chances to complete a payline and score yourself a win!


The intelligent striped Thundercat, Tygra, takes a swipe at the reels with the possibility of turning them Wild. If a winning combination occurs, the feature will be re-triggered!


One of the strongest and most noble of the Thundercats, Panthro, delivers a resounding blow to the reels to link reels 2, 3, 4, and 5 together to reward lucky players with identical symbols, which could help with creating a winning combination or two!


The incredibly speedy Cheetara races across the reels, shuffling the symbols as she goes. There is potential to re-trigger this feature up to 5 times.

Wily Kit and Wily Kat

The brother and sister duo, Wily Kit and Wily Kat take to the reels and discover some mystery symbols, which they place on the reels to transform them into identical symbols.


Love him or hate him, Snarf’s care for Lion-O has him hunting down Scatter symbols and applying them to the reels to help you activate the bonus feature!

Bonus Wheel

If you find at least 3 Scatters across the reels then you’ll be presented with a wheel featuring 6 segments, with each one offering a different bonus feature from the following:

Sight Beyond Sight

You’ll be given the choice of 4 Eye of Thundera symbols, all offering different rewards. Choose Lion-O for an increased multiplier, the logo for upgraded multiplier values, Mumm-Ra to end the feature, or Thundertank to be taken to another bonus. If the Thundertank is revealed three times then you could trigger any of the other five bonuses.

The Black Pyramid

This pick-me bonus will allow you to choose one of the three features. If you reveal Lion-O, the mighty leader will move you along the pyramid; if you find the logo then the pyramid’s bonus will be upgraded; if you discover Mumm-Ra then the feature will end. An arrow moves you further up with the intention of hopefully triggering another feature if you manage to make it all the way to the top.

The Ever-Living

This is a free spins feature with a multiplier bonus to maximise your winning potential! You’ll be awarded a multiplier of a random value between 2x and 5x which will apply to any winning spin during the bonus. Find at least 2 Mumm-Ra symbols to get even more free spins!

Hear The Roar

Lion-O takes the lead in this free spins feature, offering himself up as a special symbol that could upgrade other symbols! Once you’ve finished your free spins you have the potential to trigger even more spins by picking an Eye of Thundera!

Thundercats Hooo!

In this free spins feature, you’ll receive Wilds that will become locked until your free spins end. Keep your eyes peeled for Wild reels as this will reward you with an additional five spins to keep the fun going!

Ancient Spirits of Evil

Ancient Spirits of Evil is a pick-me style feature that will reveal one of five possible outcomes. If Lion-O appears then the wheel will spin; if the logo is revealed then you’ll be moved up to the next ring; if the red arrow is unveiled then more red arrows will be added to the wheel to give you more opportunities to be moved to the next ring of the wheel; if your choice results in an upgrade symbol then the wheel’s values are increased; if Mumm-Ra makes an entrance then the feature will end. The goal is to get to the centre-most ring of the wheel to receive the Ultimate Thunder Bonus.

Ultimate Thunder Bonus

Choose from the available Thundercat mascots to be awarded a multiplier that will then be added to the winnings from Ancient Spirits of Evil.
