Single-player ThinkFun marble-run logic puzzle where challenge cards define a start and target, and the player builds a working gravity path.
Standard solo Gravity Maze challenge.
Gravity Maze is a solo logic puzzle that combines challenge cards with marble-run construction. A challenge gives fixed pieces and a goal; the solver places towers so gravity carries the marble to the target.
Choose a challenge card and set up any fixed towers shown. Add the listed towers to the grid in a configuration that creates a continuous gravity path. Drop the marble from the start tower to test the path. If it fails, revise the tower placement or orientation until the marble reaches the target.
Solve time; lower is better.
