Object: Colour the given map with the four colours red, blue, yellow and green.

If you found the game Colorit too easy, you will love this puzzle.

First click the main board to create a random map of regions, each region painted in one of nine colours.
Your task is to paint the map in only four colours.

Click the area on the main board that you want to colour with the colour highlighted at the right border.
With each click the colour on the right border will cycle through red, blue, yellow and green. Hence - in contrast to the original game 'Colorit' - here the paint you use in each steps is given; you don't have a choice.

You cannot paint a region with a colour that it shows already.
However, you can paint the same region repeatedly with different colours.

The famous Four Colour Theorem states that every 2-dimensional map can be coloured with four colours such that no two adjacent areas have the same colour.
Here the task is bit more complicated because you are not allowed to have EVER two areas with the same colour side by side. Hence you cannot colour an area red if one of its adjacent areas is red.

Plan your moves carefully. It is often the last tile that gets you stuck.

You lose if you created two areas next to each other with the same colour.
(Take one or more steps back if that happens).

You win when you have managed to colour the map with only four colours.
(Of course the use of keyboard keys to cut and paste is not allowed in this game).
