You need to create the puzzle picture they give you, using a single continguous color.
For example the cross:
x= color 1
o = color 2
This would be the simplest pattern:
0x0
xxx
0x0
this would work too:
ooxo
oxxx
ooxo
or this
ooxoo
oxxxo
ooxoo
But this would NOT work
ooXXo
ooXoo
oXXXo
ooXoo
you can not have any blocks of the same color touching your pattern. All adjacent blocks must be the opposite color.
