Three samples so far:
1. "Solving this
puzzle means to mark on each square of the diagram's border a horizontal/vertical
or oblique orientated arrow, so that at each inside square are pointed as many
arrows as indicated by the corresponding number." The example was also given,
and should help clarify your idea of the puzzle.
2. "Identify
the patricular location line between the starting square (S) and the finishing
one (*) that passes through all other squares (only once through each) and takes
into consideration the following meaning of the arrows: the arrow marked on
the 'n'-th square indicates the direction in which you have to look for the
'n+1'-st." Again there is a small solved example.
3. "The circles
in the diagram hide either letters 'O' or black points (dividing squares). Please
determine the structure of the diagram by using the (Spanish) words from the
list and knowing that the black points can not border each other along a side.
