Can the maze layout be changed?

Yes, the walls can be repositioned, so the course can be rebuilt into new layouts after the first assembly.

Maze

Maze turns 769 LEGO® pieces into a playable tilt-labyrinth rather than a static display model. A ball rolls through walls you arrange yourself on a platform that tips via a simple lever mechanism, echoing the wooden ball-maze games many people grew up with. The full parts list below covers all 138 distinct elements used to build it.

Description

A game, not a diorama

Most LEGO® Ideas sets recreate a vehicle, building or scene, but Maze is built to be played rather than looked at. A ball travels through a walled labyrinth sitting on a tiltable base, and turning a handle shifts the whole platform so the ball rolls toward the exit. It is the same idea behind classic wooden tilt-maze toys, rebuilt entirely from LEGO® bricks so the course itself can be rearranged whenever you like. That approach feels closer to a tabletop board game than a typical display piece, and it invites building the set together rather than solo.

Why the part count stays low

769 pieces come from just 138 unique elements, a noticeably smaller variety than sets of similar size usually need. That is by design: walls, base plates and connector bricks repeat throughout so the maze can be reconfigured after the initial build rather than staying fixed. It also makes replacing a missing piece straightforward, since the parts list on this page narrows down exactly which of the 138 elements to look for.

Colours that aid the build

Tan, black, light bluish grey and reddish brown were chosen partly for contrast during construction: light and dark tones make it easy to tell walls, frame and mechanism parts apart while following the instructions. Reddish brown highlights structural pieces, while tan fills the neutral maze floor, so the finished course reads clearly even before a single ball is dropped in. The ball itself contrasts with the walls so it stays easy to track while playing.

Replay value after the build

With no minifigures included, the tilting mechanism is the whole point, and it keeps working long after the initial build since walls can be lifted out and repositioned to create fresh layouts. That makes Maze a reasonable pick for anyone who wants a LEGO® set that stays interactive rather than becoming a shelf piece, and a good one for families or puzzle fans who enjoy redesigning a course together.
