Unfortunately, they've moved to electronic instructions for many of their kids sets that also include electronics. You have to use the iPad/Android app to assemble. For example, the playable Super Mario kits.

Now, as far as I've seen, this is limited to kits that are designed to use their apps for play. Those apps are really cool though, so I am willing to look at it benevolently (all the more complicated steps give you an optional assembly video for that step which makes it nicer for smaller kids).

The app for the Duplo train is really surprising. It lets you mirror your custom track setup in the app and then play games with it while controlling the train.

From what I can tell, for those sets without physical instruction books, you can still get the traditional instructions in PDF form from the LEGO website or in the instructions app. That way you don’t have to use the interactive instructions in the LEGO Super Mario app.

Thanks, I'll look for that. I didn't know you could get a pdf out of the app
