Smart4Mobile Seek The Bone Demo - That's the way dogs do it: Hiding their bones in the garden, but then they forget where they buried them! Please help our dogs to retrieve their bones. Every dog has hidden exactly one bone which is located in a field either right, left, above or below him - never diagonally. Two bones may never lie in adjacent fields, not even diagonally. Numbers at the borders of the grid show how many bones are hidden in each row and column.
