This puzzle is a modified and expanded version of the classic Roll Over Puzzle originally invented by John Harris.

In the original puzzle, loose cubes are placed inside a box. In this version, the cubes are enclosed within a frame so they cannot fall out, while still being able to roll freely.

The puzzle has been redesigned for 3D printing and expanded to support multiple board sizes and cube configurations, offering a variety of challenges and difficulty levels.

Difficulty levels:

Challenge 1 – Empty Top - Easy
Move the cubes so that all blank faces are on the top.

Challenge 2 – Parallel Lines - Hard
Rotate the cubes so that the line faces are on top and all lines are parallel.

Challenge 3 – Number Match - Very Hard
Each cube has a number on one face, and the base of the puzzle contains numbered positions.
 

The goal is to place each cube:
above the matching number with the numbered face facing upward in the correct orientation

Important Assembly Note

When assembling the puzzle, make sure that each cube is inserted with the numbered face pointing upward.

After assembly, the cubes should already be in the correct positions and orientations corresponding to the solved state of Challenge 3 (Number Match).

Starting from this configuration ensures that all challenges are solvable. If the cubes are inserted in a different orientation, some challenges may become impossible to complete.
