Slot Details

Thunderbirds is a video slot with five reels, three rows, and 20 fixed pay lines. Join the heroes on desktop or mobile for 0.20 to 100 credits. The RTP of this medium variance game is set at a ratherlow 94.31% with the maximum win potential per round limited by the provider at 250,000 credits, which at maximum bet would be 2,500x. However, the actual win potential on a single spin stands at maximum 500x your bet.

The entire game is set inside a Thunderbird spaceship in front of a window looking out into the blue sky. The game buttons mimic spaceship controls with the spin button being the ship’s radar. The premium symbols are the characters and props from the sci-fi series while the original soundtrack provides the main audio.

The authentic desing continues with the pay symbols, starting with the card royals 10 to A at the low end. Hit a five of a kind to win up to 4x your bet. At the high level, you will find Penelopes’ limousine, the mother spaceship, Jeff Tracy himself and a tile depicting his five sons – Scott, John, Virgil, Gordon and Alan. Pays for a single five of a kind range from 6x to 25x your stake.

The wild symbol is Aloysius Parker, the chauffeur and butler of Penelope, who in turn is the organisation’s agent based in London. The three bonus games are triggered by two F.A.B Supermarionation symbols and one of three bonus symbols on reel five – The Hood, Vault of Cash, and Thunderwilds. Scatters are a globe with the word with Superspins across it.

The Thunderbirds Random Features

Get ready to experience a frenzy of random features that involve the five Thunderbird vehicles from the series. They can trigger on any spin in the base game and free spins, each applying a reel modifier that can help to create more or bigger win combinations.

Thunderbird 1 will fly past the game window to drop a random number of regular symbols onto the reels. It can repeat the mission if no win was created on the first drop.

Thunderbird 2 will fly across and drop one win multiplier onto a random position.

Thunderbird 3 will take off from the bottom and transform one random reel into a stacked wild.

Thunderbird 4 will appear after a win and remove the winning symbols to drop new ones into place. This continues until no new winning combo occurs after a fresh drop.

Thunderbird 5 will award five spins where on each spin it passes the reels to drop a number of random wilds.

The Tunderbirds Bonus Games

After devouring the five random features, it is now on to the three bonus games. Hitting a F.A.B Supermarionation Bonus symbol on reel one and three as well as either the Vault of Cash, The Hood or Thunderwilds symbol on reel five will trigger the respective bonus game.

The Hood will lead to the Temple of Treasure game where players select first the level of difficulty which is directly linked to the win potential. The higher the difficulty, the higher the coin wins but also the more Hood symbols are added to the game grid. In the second phase, players work their way through a field with 15 positions one pick at a time to collect coin wins. Unveiling The Hood will end the round.

Vault of Cash is a two-wheel feature where the inner wheel has coin wins and the outer either ‘spin’ or ‘stop’ segments. You get to turn the wheel and collect coin wins until the outer wheel halts on ‘stop’. The vault can randomly open at the end of the round to unveil a multiplier of up to x100, which will be applied to the total winnings from the bonus game.

Thunderwilds will add a random number of wilds on reels one to four, while the triggering wild on reel five expands to cover the entire reel. The game will respin and the wilds will move by one step to the left until disappearing from view. Wins are accumulated throughout the respins and paid once the feature ends.

The Thunderbirds Free Spins and Super Spins

You think it is all over? Think again, as the slot comes also with two types of free spins. Landing three scatters anywhere on the reels will trigger a select number of free spins where all random Thunderbird features and the Vault of Cash bonus game will trigger more often.

Occasionally, the game will trigger enhanced Superspins with expanding Thunderwilds that can appear on all reels. The feature cannot be retriggered.

Final Verdict

Storm Technologies did the epic series justice with their Thunderbirds slot, creating an authenthic feeling and engaging gameplay. The win potential is somewhat unclear, but should be around the 1,500x – 2,500x bet mark in the Superspins round. However, with the sheer amount of random and bonus features, the gameplay is more focused on medium sized wins in 50x to 200x the bet region.
