About Mystery Express Slot

Another showstopper brought to you by the guys at IGT who have created some of the most popular online slots here at Castle Jackpot. Just a small uncovering of their talents can be seen in the Egyptian themed megahit Cleopatra slot alongside the fantasy driven Pixies of the Forest slot. Mystery Express is a slot game played across 5 reels with 30 paylines and a default coin value of 30 where players can stake as low as £0.30. At Castle Jackpot, we have always shouted the loudest about our diverse online casino games arsenal and we continue to strive towards the ideal that we can provide all types of games for our players.

How to Play Mystery Express Slot

Set your Stake

To set the game in action, simply select the amount you’d like to stake using one of the three sections at the bottom left of the screen. Players will automatically be set with 30 paylines and can change the amount they’d like to stake by altering paylines or bet value.

Spin the Reels

When you’re happy with the desired stake, press the larger spin icon on the bottom right hand corner of the screen to set the reels off.


Like all great slot games, Mystery Express allows players to set an autospin function from 10 to 50 spins automatically.

Mystery Express: Bonus Rounds

Mystery Wilds

Triggered during the base game, players can activate the Mystery Wilds feature on any spin that doesn’t contain a Wild symbol on the first reel, or a Bonus symbol on any of the other reels. Once in play, trains shall appear and subsequently convert 1 to 5 reels into Wilds.

Level Up Plus

The Level Up Plus round is probably the most exciting bonus feature in this slot game, allowing players to progress around the board and to collect points as they do so by rolling the dice and landing on bonus features. When activated, players can land free tickets, multipliers or mini slots. Keep an eye out for the Travel Experience Points Meter at the top left on the screen that will allow players to level up throughout the game. The levels are as follows:

1 . Traveler - The train will start in London with a Mini Slot machine and Wheels being copper.

2 . Voyager - The train will be in Paris with the Mini Slot machine and Wheels, however, they shall be bronze with higher rewards available. 200 points are required for this level.

3 . Adventurer - The train shall be in Venice with a Mini Slot machine and Wheel where they shall be silver. 500 points are required for this level.

4 . Explorer - Collect 1000 points to unlock the Mystery Box Feature.

5 . Globetrotter - Collect 2000 points to start this level. The train begins at Istanbul with the Mini Slot machine and Wheel being coated in gold.

Bon Voyage Bonus

Trigger this feature by landing Scatter symbols on reel 1, 3 and 5 where you’ll be taken to a board where you will roll the dice to land fantastic bonuses. They are as follows:

1 . Extra Ticket - land on the ticket symbol to be granted 1 or 2 free extra rolls of the dice. Players can land up to a whopping 50!

2 . Multiplier - players can multiply their initial stake between x2 to x10!

3 . Mini Slot Bonus - Landing in Paris, Brussels, Belgrade or Budapest, you will receive Wild Symbols of x2, x3 or x4 your initial stake!
