For Europe, this is a separate app called Ticket To Ride Europe Pocket for Iphone/Ipod Touch.
$2 (if you wait enough, it may go down to $1 or even free
Not to be confused with the US map for Iph/IpT (Ticket To Ride Pocket) nor the version tailored towards Ipad (just "Ticket To Ride"), of which the Ipad version include all the expansions/add-ons through 1 app
Ticket To Ride Switzerland available as in app purchase (IAP) for $1http://itunes.apple.com/us/app/ticket-to-ride-europe-pocket/...
** What’s in it?
• The map of Ticket to Ride Europe
• A new AI bot, PoirBot, specifically designed for Europe
• 5 new European-specific achievements
• The map of Ticket to Ride Switzerland (available as an in-app purchase) that also comes with its own specific bot, EscherBot
• The same Conductor Level and Pressure Gauge achievements first introduced in Ticket to Ride Pocket; they can now be saved online and take into account Online games played with other copies of Ticket to Ride
• The same SOLO, PASS-and-PLAY, LOCAL and MULTI modes, and leader boards, that made the original Ticket to Ride Pocket so popular
Last but not least, I am glad this came out despite comments from DoW/devs saying while US map worked out nicely for Iph/IpT, Europe/Swiss/other maps didn't seem feasible due to more detail on those maps, requiring a larger screen.
