Description

A kit for tasks, not one fixed model

Unlike a typical LEGO set, this kit doesn't come with a single official build for a main model. Instead it supplies a broad range of parts that teams use to design their own task-specific models as part of the competition. One minifigure is included, flexible enough to slot into whichever scenes or challenges a team builds rather than representing one fixed theme. That openness sets the kit apart from themed sets built around one predetermined, piece-by-piece plan, asking teams to bring their own planning and ideas instead.

Grey, black, white and blue as a neutral base

The colour palette of light bluish grey, black, white and blue is deliberately neutral, with no single theme dictating the look. That makes the parts easy to use across very different contexts, from technical builds to open-ended challenge models. With 231 unique parts, the set provides a solid base collection, with the exact composition listed in the parts list on this page. Because the shapes aren't tied to one particular look, many basic pieces can be reused several times and for very different purposes within a single challenge model.

Who this set is for

The kit is aimed primarily at teams and groups taking part in the FIRST LEGO League or working on similar open-ended building challenges, rather than solo builders expecting a finished model. With 1,600 pieces, there's enough material for several smaller builds at once, which suits group work and repeated building and rebuilding. As new challenges arrive with each competition season, the kit stays useful across several years of competing rather than being retired after a single project.

A versatile parts base

Because the parts are neutral in both shape and colour, the set also works as a base collection for personal technical projects outside the competition context. Anyone specifically after grey, black or blue technical and structural parts will find every colour and quantity listed in full in the parts list on this page. Even away from the competition, the neutral shapes work well for recreating simple tools, basic machines or a first set of Technic-style builds for beginners.
