Are Mega Bloks and LEGOs compatible?

Most sets within the Mega Bloks line are compatible with LEGO blocks. However, the micro or nano sets are built in a different ratio and are not compatible.

Mega Bloks is a Canadian-based company referred to as a LEGO clone, which means that its building blocs are generally compatible with the LEGO brand. The company is considered one of LEGO's biggest competitors. It owns a large portion of the market by having many third-party licences, such as Hello Kitty, The Smurfs, Barbie and World of Warcraft. Some consider LEGO sets higher quality than Mega Bloks sets, but others attest that, for the price, Mega Bloks are a great alternative.
