Instructions are very clear & allows you to build at your own pace by remaining on screen until you click the button to continue. The 3D aspect is pretty cool & will be helpful on bigger builds. I do have one minor complaint. When I tried to scan the QR code to pull up the instructions for this set, nothing happened. I had to search for the set manually. It showed up right away with no further issues. No big deal, just thought I'd mention this small glitch. Otherwise, I found it very helpful.

Been using the "Build together" option on the Lego builder app for the Chinese New Year Dragon. it is really fun to do as a family. Only problem i encountered was the massive battery drain means we had to pause to recharge. Was using it with an 8 year old with no difficulty as the app is very clear when to pass each other stuff, and as components built are small it turns a more difficult project easier. Added bonus was it stopped one person from taking over all the building. So more fun for all.

Thanks for taking the time to leave us a review! We're glad to hear your family had so much fun building together with the help of our LEGO® Builder App. If your device’s battery is draining faster than usual, try closing all the apps in the background. If you have any questions, let us know at Happy building!

Amazing app!! You can add finished projects to your collection when you're done building within the app. the little animations when you complete a section that goes onto another section are fantastic. Feels like you're winning a small prize every time you get to a new bag. Super clear step by step. Will use the app over the paper book sometimes just for the fun animations and the rotating pieces display.
