Map
|
||
|
|
<p>
|
||
|
|
Colour the map with four colours, so that no two adjacent regions
|
||
|
|
have the same colour. (Regions touching at only one corner do not
|
||
|
|
count as adjacent.) There is a unique colouring consistent with the
|
||
|
|
coloured regions you are already given.
|
||
|
|
<p>
|
||
|
|
Drag from a coloured region to a blank one to colour the latter the
|
||
|
|
same colour as the former. Drag from outside the grid into a region
|
||
|
|
to erase its colour. (You cannot change the colours of the regions
|
||
|
|
you are given at the start of the game.)
|
||
|
|
<p>
|
||
|
|
Right-drag from a coloured region to a blank one to add dots marking
|
||
|
|
the latter region as <em>possibly</em> the same colour as the
|
||
|
|
former, or to remove those dots again.
