Our Take
Gravity Maze is a single-player marble-run logic puzzle from Ravensburger in which you build a 3D tower path to guide a marble from start to a target. Aimed at children aged 8 and up through to adults who enjoy spatial-reasoning challenges, it sits firmly in the "brain game" category alongside titles like Rush Hour and Chocolate Fix.
Key Features
Includes 60 challenge cards graded across beginner, intermediate, advanced, and expert levels
Comes with a set of transparent, coloured plastic towers of varying heights that interlock on a grid base
A single steel marble is used as the playing piece throughout all challenges
Each card dictates which towers and the target piece must be placed in fixed positions before solving
The grid base holds towers securely, preventing accidental displacement during play
Box doubles as storage with card compartments, keeping all pieces organised
Our Verdict
Gravity Maze is a strong buy for independent, puzzle-minded children of around 8–12, or adults who enjoy quiet solo brain teasers. Families seeking a multiplayer game night option should look elsewhere, as should those wanting long-term ongoing replayability without purchasing additional challenge sets.
