It is the sequel to Mini Yonku GB Let's & Go!!. However, there is no communication element with the previous work. It follows the same system as the previous work, such as the parts age system, parts strengthening with iron core furnaces, communication exchange of parts, and the existence of hidden parts that can only be obtained by communication exchange.

As the name of "MAX" suggests, Goki, Retsuya, and Marina, who are the main characters of "MAX", which is the sequel to WGP, will appear as guests after the ending.
