Rules

Objective is to drag bi-colored tiles forming a squared pattern on given board positions to match certain requirements as listed below. The size of the squared board is measured by its width in tiles. So if it is eight tiles wide and high the squared board has 64 positions. The amount of available different colors in the color palette matches the size of the board. Each of the rectangular shaped unique tiles has two combined attributes: a frame color and an inner color.

Besides using the board positions for the tiles these can temporarily be placed onto the spare area below the board. To solve the puzzle all tiles have to be positioned on board so that

• each frame color must occur exactly once per horizontal row and vertical column and
• each inner color must occur exactly once per horizontal row and vertical column.
