All aboard the DUPLO Train! Join the train driver on an adorable adventure through rolling hills and green pastures.

Play with the driver, tickle him or feed him if he gets hungry!

Place DUPLO Action Bricks on the rails to make the driver react to your actions. Each Action Brick can also launch an exciting activity that bridges the gap between the physical and digital worlds: stack crates onto the train with the boat driver, repair the train’s headlights using colored lightbulbs, help the driver wash the mud off the train or play hide and seek with your squirrel friend! There is a total of 7 exciting activities to discover.

- Adorable, funny and toddler-friendly visuals, animations and interactions

A lot of fun

My 4.5 year old son and I really enjoy this app. He could figure it out on his own and it taught him a few new builds. Some really awesome feature for a free app.
Thank you.

Obviously not tested on children

Virtually every control for the train is right on the edge of the screen, and you slide your finger to operate the controls. Well, guess what? Apple engineers use the exact same ‘swipe from the edge’ motion to switch between apps. Try explaining to a 2 or 3 year old that they can’t actually touch the edge of the phone when trying to grab the speed control knob which is literally .1” away from the edge of the screen. If your child isn’t exactly precise in their finger position they end up starting to switch between apps, and the instant you begin to switch apps, the Bluetooth connection is disconnected and you must wait about 5 seconds for it to reconnect. Incredibly frustrating. Even more so when you realize all the LEGO developers had to do to discover this issue is let one or two children use the app for all of 5 minutes before they realized how big of a design flaw this layout is.

Did developers test this app on an iPad?

Concur with others... the train won’t connect with my iPad Pro. Inches away, Bluetooth is enabled, and location services are on (the app doesn’t appear on the Location Services list, so can’t be enabled individually).

Also, for anyone that uses an iPad with a stand (almost everyone) the app is stuck in an upside down position.

So yea, not good.

Developer Response ,

Ouch! The app is optimized for phones and will remain in a vertical display setting, so it doesn't have good synergy with the iPad stand, unfortunately. As for not able to connect your train with your iPad: The LEGO® DUPLO® Connected Train base uses Bluetooth Low Energy to create a connection to your device, so no pairing through the Bluetooth menu is necessary. Simply launch the app, turn the train base ON (click on the green button under the train) and hold your device close to the train base. Ensure Location Services are enabled. Please check if the white light is blinking and try to connect to the train. If the light is not blinking and it's just turned, please restart the train and try again.  Please contact us, if you still have any issues: We'd love to help you! - Samuel -
