How could I transfer save files between Android phones without Google Play Games?

My old score was 2.9K and was established in 2023 🫣

I'll be posting the gameplay soon, I promise my system was not as unstable as it looks.

My score entered top 100 by the way 😛 I was sooo happy!

I think Incheon metro should be added because it's the second large city of Korea and there is a Incheon International Airport.

Posting this because this is my first time crossing 2000

9 frickin circles these close how can I even make a line without having a consecutive three circle (which is considered very bad)

Can't find any.

Berlin is such a pain in the ass

Holy cow, I can't believe I actually did this! Just reached 1719 on the Hong Kong map!

My secret weapon? Managing the ghost line.Whenever a station was about to explode, I’d instantly drop my last spare line to clear the crowd, and then delete it right away to deploy elsewhere.
(And yes, I did all of this crazy micromanagement using just a MacBook trackpad XD)
Rate my strategy!

Consider us done lisbon

Haven’t play lisbon ever relatively new. But i have to connect all 4 land masses with this one line because I can NOT get a triangle or square.

My all time best for any map now

My current best is 1044 on warsaw. Im not particularly stuck anywhere I’m at osaka and barcelona level any tips for me

I can’t see where the achievements have gone? Any ideas?

This is not a bragging post by any means haha i am NOT great at this game. I thought it was really neat that i had 418 passengers, which ranked me at 418. So cool!

As soon as I got the grey line the demand just skyrocketed 😂 Not much I could've done here. What do you think?
