Relive the golden age of early 20th-century train travel and a mystery surrounding the death of a passenger as you steam towards a potential prize. Mystery Express, a 5-reel, 30-payline casino slot game by IGT, is a 2020 release that gives players a chance to win up to 1,000x their original stake.

So if you enjoy playing online casino games that have a travel or mystery theme, this title offers an engaging storyline and plenty of game features and bonus rounds, which we’ll cover in this review.

Game overview

There’s plenty to enjoy for fans of online slot machines with exuberant color, vibrant graphics and an intriguing backstory in the adventure-travel genre. Players have four features to enjoy: the Bon Voyage bonus, Level Up feature, Mystery Box feature and Mystery Wild bonus feature. This medium-volatility game has an RTP (return to player) of between 94% and 97%, which gives players a medium-risk chance at some solid rewards, up to 1,000x the original stake.

How to play

To enjoy Mystery Express, follow the steps you’d usually take to play slots online.

  • Check out the game rules and paylines by looking at the paytable.
  • Decide on your total bet at the bottom left of the screen (this can be between 0.30 and 600 coins per spin, with the line bet coin value ranging between $0.01 to $20.)
  • Now simply tap the Spin button to start playing.


The backstory for the Mystery Express online slot – as you may already have guessed – is loosely based on Agatha Christie’s 1934 classic novel, Murder on the Orient Express. The high-resolution graphics, which include a Victorian lady and gentleman, pocket watches, a slice of cake, a revolver and a glamorous steam train, are impressive and will have you steeped in all the mystery and drama in no time at all.

While preparing to play this online slot for real money, you’ll discover that a professor-explorer has died on the train as it steams across England and Europe, starting from London, with Big Ben in the background. The slightly eerie soundtrack adds to the intrigue and excitement as you race ahead to find the treasure accumulated by the professor.


There is no shortage of features to increase your chances of winning in this online casino slot. Keep in mind that Mystery Express does not offer free spins, but it does compensate with plenty of bonus mini-games.

Bon Voyage bonus feature

This feature is triggered when the “bonus” scatter symbol lands on reels 1, 3 and 5 at the same time. When this happens, you’re rewarded with 2 to 4 rolls of the dice and can go on to activate one of these features: The Extra Ticket feature, which gives you 1 or 2 extra rolls; the Multiplier feature, with rewards of 2x to 10x your wager; the Wheel Bonus feature, available on level 5, which gives you the possibility of being awarded up to 30x your stake; and the Mini Slot Bonus Feature, which sets you up to spin a mini slot machine with 2x and 4x multipliers up for grabs.

Level Up feature

This feature works like this: Each time you progress to a higher level by earning Experience Points, the higher the payout becomes. Levels start in London at the Traveler level, then move on to Voyager in Paris, Adventurer in Venice, and Explorer and Globetrotter in Istanbul.

Mystery Box feature

Get to Explorer level by earning 1,000 Experience Points and you’ll trigger the Mystery Box bonus feature. Now you have 3 mystery boxes to choose from to win up to 200x your total wager.

Mystery Wild bonus feature

In this bonus feature, the train moves randomly between reels 1 and 5, and if you’re lucky enough to land 5 fully wild reels, you’re rewarded with 1,000x your total stake.

Bonuses and jackpots

The top prize in Mystery Express is 1,000x your total stake. This occurs when the wild symbols cover all positions on the reels. The payout can also occur as part of the random Mystery Wild bonus feature. As a medium-volatility online slot, gameplay presents an intermediate level of risk for medium-value rewards.
