jujubes : (four red and four green)
I am not sure this works with other colours...try and let me know!
Draw a number line : 1 to 10
Place the jujubes in alternating colour sequence.
Leave spaces 9 and 10 open.
Challenge: While moving
two adjoining jujubes, without
changing their sequence, rearrange them so that
all the green ones will be on the left
and the red ones will be on the
right. The jujubes can
only occupy blank spaces.
It must be done in only four
Should you succeed...your reward : a jujube feast!
