After selecting the desired bet configuration, press AUTO SPIN, and choose how many spins to play at the current bet settings.

Auto Spin plays the specified number of spins until STOP is pressed, a bonus is triggered, the balance is insufficient to spin, or any enabled win/loss limit settings are reached.

Auto Spin is only available in approved jurisdictions.

Mystery Wild Bonus

The Mystery Wild Bonus can be triggered after any base game outcome that does not contain a Wild symbol on the first reel or a Bonus symbol on any reel. When the Mystery Wild Bonus triggers, trains randomly appear and turn 1 to 5 reels to Wild reels. After 1 to 5 reels are turned wild, all wins are evaluated and paid based on this new final reel state. No wins are awarded before this final state.

Bon Voyage Bonus

Trigger the Bon Voyage Bonus when three Bonus scatter symbols appear anywhere on the first, third and fifth reel. If there is a Bonus symbol on the first and third reel and no win, there is a second chance for the Bonus symbol to appear on the fifth reel and trigger Bon Voyage Bonus. Pick one of the three Bonus symbols to reveal the initial number of dice rolls: two, three, or four.

Depending on the level reached, the journey could start from London, Paris, Venice or Istanbul. Press the ROLL button to roll the dice and move the train around the map.

Different bonus features are awarded around the map.

Extra Ticket:

Landing on an Extra Ticket spot awards 1 or 2 extra rolls.


Landing on a Multiplier spot awards from 2 to 10 times the total bet.

Mini Slot Bonus:

Landing on Paris, Belgrade, Budapest, or Brussels triggers the Mini Slot Bonus. The Mini Slot machines offer richer and richer awards with 2xWild, 3xWild and 4xWild symbols as the levels increase. See the paytable for details.

Wheel Bonus:

 Landing on London, Venice, Istanbul or Vienna triggers the Wheel Bonus. Wheel awards are richer as levels increase. See the paytable for details.

Mystery Box:

Landing on a Diamond spot has no effect until the Explorer level. At the Explorer level, the Diamond spot becomes a Mystery Box spot. Pick one Mystery Box and win up to 200 times the total bet.

The Bon Voyage Bonus is limited to 50 dice rolls.

Level Up Plus Feature

Each time a Bonus symbol appears on the reels in the base game, Travel Experience points are awarded. Earn more Travel Experience points and level up by:

  • Triggering the Bon Voyage Bonus
  • Landing on Extra Ticket spot
  • Landing on Mini Slot Bonus spot
  • Landing on Wheel Bonus spot

Travel Experience points persist across play sessions and are carried over from game to game.

The Travel Experience points meter, visible in the top-left corner, shows the Travel Experience points balance and the percentage of completion required to reach the next level.

When the Travel Experience points balance reaches certain thresholds, level up is awarded. See the paytable for the thresholds. When a level up is triggered, a new title is awarded and immediately unlocks new Bon Voyage Bonus features.

Misuse or malfunction voids all pays and plays.

All line win symbols must appear on a played line and on consecutive reels, beginning with the far-left reel.

Only the highest winner is paid on each payline. Line wins are multiplied by the line bet on the winning line. Coinciding line wins on different paylines are added.

The Wild symbol substitutes for all symbols excluding the Bonus symbol.

Bon Voyage Bonus wins are independent from line wins and are added to the total amount paid.

Bonus scatter symbols appear on reels 1, 3, and 5 in the base game only.

Wins are shown in currency.

In some jurisdictions, regardless of bet size, there is an award cap on any single transaction. See the paytable for details. A transaction includes the results of the bonus, plus the outcome which launched the bonus. If the award cap is reached in the bonus, the bonus ends immediately, even if there are remaining free spins.

Additional Information

Expected Payback

In accordance with fair gaming practices required in most legal jurisdictions worldwide, each and every game outcome is completely independent, except in cases where one spin unlocks a feature for a subsequent spin or series of spins, per the game rules. The odds of getting any particular outcome are always the same.

The odds do not vary based on prior outcomes, bet size, balance size, time of day, day of week, etc. For example, if the top award is won on a given play of the game, the chances of winning the top award on the next play are exactly the same. Likewise, prior losses do not change future odds.

The expected payback reflects the theoretical return across a very large number of plays by numerous players over an extended period of time. The results for any given player over a play session can vary widely from this long-term, expected average in either direction. The fewer the number of games played, the wider the normal variance of actual payback that may be experienced.
