Here you can find a sign and a marker that give you the numbers abcdef.


Note the numbers and walk to the beach.

Pick up 12 shells and search 18 small pieces of wood.
After collecting the 30 pieces look for an empty place on the beach.


You need about ca 2m in square.

Draw into the sand a star with 6 corners.


Divide every corner of the star into 10 parts as shown.


Mark in every corner 3 star-fields (*) with a piece of wood.
Corner A with the figure corresponding with sign-number a (not 0 !).
Corner B with b, and so on.

Put 12 shells on the sand-star.
2 shells in every corner
according this yellow star.


Then count all shells in all 6 corners that are on a marked field.
You will get an uneven number for T.

To get the next number V you have to move the 2 shells from corner A into corner B.
Be carefully to place the shells on the same field position as before!
Shells from corner B into C and so on until F into A.
After moving all 12 shells count again how many shells are on marked fields.
This is V.

Reply this procedure another 4 times and you will get the remaining 4 numbers WXYZ.
Check your numbers: EUU-UUU (even/uneven), total 31.
Now you can walk to the final at N37°06.TVW W8°39.XYZ (obvious object)
Feb.2024: New hiding place. Task is been modified. If you have the old coords enter these into the checker and you get the new place.
