INSTRUCTIONSÂ
Choose a puzzle pattern. Place the markers with the targets facing up on the grid, in the positions and using the colours indicated on the chosen puzzle pattern. Place the remaining crosses in the free spaces, with the coloured side facing up, such that each colour only appears once in each column (vertical), row (horizontal) and in each of the 6 blocks.Â
To win, you have to complete the pattern without repeating the colours.
