New Zealand Puzzle
The idea is to replace all the pieces back on the board according to the following rules: 1) No symbol may be put on the same symbol (ie not sheep on sheep). 2) No symbol may be laid beside the same symbol, neither horizontally, vertically, nor diagonally. 3) If a piece is laid down, the covered symbol is no longer useable. 4) Once a piece is laid down, it may not be removed. 5) If there is no further possibility to lay, the puzzle starts from the beginning.
