Super Thunder Express Overview

Super Thunder Express is a classic fruit slot with a steam train and thunder theme from Fugaso, released on 10 September 2026 as part of the Trinity Series. It plays on a 5x3 grid with 10 fixed paylines, and wins pay from the leftmost reel to the right.

The game rules list an RTP of 96.15%, and the volatility is medium. The maximum win is 5,000x the bet: when the total win of a round reaches this limit, it is paid out and the round ends immediately. Bets range from 0.10 to 50 per spin.

The main attraction is the Running Wins Bonus Game – a respin feature with coloured Special Bonus symbols, cash prizes and four fixed jackpots. It can be triggered by collecting symbols, by the random Lucky Riches feature, or bought directly with the Buy Feature.

Theme and Graphics

A shining black steam locomotive races through a dark blue night above the reels, with lightning bolts flashing around it. Under the train, three round Collectors show small locomotives in green, red and blue, labelled Green Bonus, Red Bonus and Blue Bonus.

The reels hold traditional fruit machine symbols: cherries, lemons, oranges, plums, grapes, watermelons, golden bells, the BAR sign and the red lucky 7. On the left, the four jackpot meters – Grand, Major, Minor and Mini – are always visible, and the values change with the bet.

Special Bonus Symbols

The Special Bonus symbols are golden coins with a lightning bolt, and they come in four colours: Green, Blue, Red and Gold. They can land on any reel, but they pay only during the Running Wins Bonus Game. Only one colour can appear per spin, and it lands in groups of 1, 2, 3 or 5 symbols.

Every Special Bonus symbol that lands is collected into the Collector of its colour, and each collection has a chance to trigger the bonus. Landing 5 Special Bonus symbols on the same spin guarantees the Bonus Game immediately. Green, Blue and Red symbols trigger the Running Wins Bonus Game, while Gold symbols trigger the Running Wins Super Bonus Game. When the bonus triggers, more symbols of the same type are added until there are 5 on the reels.

Running Wins Bonus Game

The bonus starts with 3 respins, and every new Special Bonus symbol resets the counter to 3. Only symbols of the triggering colour can land, up to 5 per spin, and each one sticks to the reels until the end. The feature ends when all positions are filled or the respins run out. Then every symbol receives a prize:

  • Green: 1x, 2x, 3x, 4x or 5x the bet, or the Mini Jackpot,
  • Blue: 3x to 10x the bet, or the Minor Jackpot,
  • Red: 6x to 14x the bet, or the Major Jackpot.

Super Bonus Game and Jackpots

The Super Bonus Game follows the same rules, but every Gold Special Bonus symbol is awarded a jackpot prize: Mini, Minor, Major or Grand. The jackpots are fixed multiples of the bet. At a bet of 8, the meters showed Mini 120, Minor 200, Major 800 and Grand 4,000, which is 15x, 25x, 100x and 500x the bet; at a bet of 30, the Grand Jackpot showed 15,000.

In our session, five Gold coins landed on one spin and started the Super Bonus Game, and the round paid 1,640 at a bet of 8.

Lucky Riches Feature

Whenever a coloured Bonus symbol lands in the main game, the Lucky Riches feature can be activated at random. It adds enough Bonus symbols to the reels to trigger the Bonus Game.

Buy Feature and Bonus Hunt

The BONUS button on the left opens the Buy Feature menu with three options:

  • Bonus Hunt: costs 2x the bet per spin and makes the Running Wins Bonus Game 5 times more likely to trigger,
  • Running Wins Bonus Game: 80x the current bet,
  • Running Wins Super Bonus Game: 200x the current bet.

Paylines and Base Game

The 10 paylines are fixed, and only the highest win per line is paid. In the base game, wins come from the fruit symbols, the bells, the BAR and the 7s. In our screenshots, a line of watermelons with a red 7 paid 90 at a bet of 30, while the lightning effects ran along the winning line.

Who Should Play It

Super Thunder Express is for players who like classic fruit slots with a modern hold-and-win bonus, fixed jackpots and the option to buy the feature. Try the free demo first.
