Colourku

In this adventure map, you will find 9 puzzles with different difficulty levels: stone buildings are the easiest, brick buildings are medium, end stone buildings are the most difficult ones.

For each puzzle, there is a wall of 9 * 9 blocks with different colours. Some blocks are given and cannot be changed, blocks that have lever attached can be changed to a different colour by flipping the lever.

The game rule is the same as Sudoku, you need to arrange the colour blocks so that each colour can only appear once in a row, column or box (3 * 3 square). Also each puzzle has one and only one solution, 

solution for each puzzle can be found from the back side wall.

Enjoy 🙂
