Moshe's Insanity


Moshe’s Insanity is a fascinating puzzle based on the game Instant Insanity. It was created for the ACM ICPC competition in 1994. The premise of the puzzle is relatively straightforward: you are given eight cubes, and your task is to arrange these cubes in a 2x2x2 arrangement so that each side of the finished puzzle displays solid colors. Here are the key constraints for Moshe’s Insanity:


1. Each of the eight cubes has six sides, each colored with an individual color.

2. No duplicate colorings are allowed on a single cube.

3. The eight cubes can include duplicates.
The main goal of the project related to Moshe’s Insanity is to allow users to interact with the puzzle and determine if their set of cubes can produce a valid solution.


Specifically, this means:

1. Allowing users to input their own cubes or use a set of randomly generated ones.

2. Enabling users to place their cubes into specific positions within the puzzle.

3. Allowing users to rotate cubes within the puzzle.

4. Providing a way for users to check if their set of cubes is solvable.
