The LEGO BOOST Expert Book: Building and Programming Instructions for 6 additional models based on the Boost-Set Paperback – 18 July 2019

First of all we built the marble run and that was very difficult to build but very cool when finished . Then next we built the rubix cube solving robot . It was easy to build but difficult to programm . When it was finished it was absolutely AWESOME!!!!!!Sometimes the building instructions were not very clear.

Great extension to LEGO BOOST
