A little help
for your city.

Open Menu → How to Play to see the city-building guide. It takes you through stations, tracks and routes.

After building stations and connecting tracks, choose Build → Routes, select stops in order, and create a route. If you created it with Deploy Trains disabled, add a train from the route list.

You need operating trains, accessible jobs and shops, food, and empty land. Housing grows over time even after these conditions are met. Tap the demand bars at the top to check the reasons for shortages.

Shops, offices and farms you build accumulate revenue. After 5 minutes of real time, a coin marker appears above the building. Tap it to collect. The amount depends on visitors, employees and farm utilization.

The population requirements are 500 for medium, 2,500 for large and 10,000 for extra-large facilities; 5,000 for 6-track stations and 10,000 for 8-track stations. After reaching a requirement, tap the lock in the building catalog to check the diamond cost and unlock that option.

Each type and size is unlocked once. Diamonds spent on unlocking are separate from the coin construction cost. Small facilities and 2-track and 4-track stations are available from the start. Elevated Tracks become available after a one-time unlock costing 10 diamonds.

Offline revenue from your own buildings is estimated from their utilization before you left. Absences under 15 minutes add it to the buildings’ uncollected coins. For absences of at least 15 minutes, you can watch an ad on return to claim it. Up to 5 hours are eligible.

If you forfeit or close the reward screen, that offline reward cannot be claimed later. Coins already in buildings before you left remain. Train fares do not accrue while the app is closed.

The app saves periodically and when you leave it. To save manually, choose Menu → Save and keep the app open until “Game saved” appears. Unconfirmed construction plans are not saved; confirm them with Build All.

If the operating system suddenly terminates the app, your latest actions may not be saved. If saving fails, contact support before deleting the app.

There is no game-specific cloud sync or account-based transfer. iPhone and iPad migration and backups such as iCloud are operating system features. We do not guarantee that every migration method restores the city. Signing in to the same Apple Account alone does not synchronize it. Keep the original app and device data until you verify the transfer.

If the recovery screen offers Restore from Backup, read the explanation before restoring. Recent actions may be missing because this returns to an earlier save. If recovery is unavailable, contact support instead of deleting or reinstalling the app.

Ads may be unavailable because of connection or ad availability. If Menu contains Check Ads Again, try that button. You can continue building your city while ads are unavailable.

No reward is granted if you close an ad early or reward completion cannot be verified. If this keeps happening, contact us with the time and actions involved. The public app uses Google AdMob.

Change your ad age group under Menu → Ad Age Settings. This is separate from Google’s consent choices. Depending on Google’s determination, Menu may show Ad Settings, where you can review those choices. That button is not shown to everyone at all times.

See the advertising section of the privacy policy.

If your city has a problem, contact us first. Deleting the app may erase your city, currencies and achievements; the operator cannot restore them remotely.

See the separate steps for device data, backups and support information.

Version 1.1.3, submitted for review, adds full-screen iPad support. After release, the same App Store app can be used on iPhone and iPad. This does not add automatic city synchronization between devices.

The location markers planned for version 1.1.3 follow the front of each train. Green means less crowded; the color changes through yellow toward red as occupancy rises. They hide when you zoom in close or enter Cab View. The markers display position and do not respond to taps.

Open Menu → Sound to adjust interface effects and train sounds. Version 1.1.3 also provides separate music volume, with different music for the map and Cab View. You can mute all sounds. Sound settings are saved separately from your city.

Construction calculations can take time depending on the city size and track shape. You can move the camera during preparation. Demand and estimated building usage update progressively after placement. If construction repeatedly fails to finish, contact us with your device, city size, whether you were building tracks or a building, and how long you waited.

In the upcoming English-compatible version, Menu → 言語 / Language will offer Automatic, 日本語 and English. The choice is saved and also controls the next loading screen’s game name. Changing language keeps the same city and currencies. App Store, Home Screen and website names follow their own language settings.
