Who doesn't love spending a few hours each day putting together hundreds to thousands of pieces of LEGO bricks? LEGO knows that both adults and children will spend a huge chunk of their time researching about the latest LEGO sets and learning how to assemble them in the most efficient way, which explains why the Danish company does not hold back in adding new pieces and interesting parts to keep us all hooked. The larger LEGO sets contain thousands of pieces, that you practically end up constructing elaborate and massive structures. Here, we share our top picks of the best and biggest LEGO sets ever made:
