Adjacent
Sharing a border — touching horizontally or vertically at an edge or corner, depending on context.
Explanation
In Murdoku, adjacent most commonly appears in clues about positions relative to objects or people. The exact meaning (edge-only or edge-and-corner) depends on the specific clue wording. When paired with 'beside,' it always means edge-only.
Example
A clue saying 'adjacent to the window' typically means sharing at least a corner with the window cell.
Common Mistake
Assuming adjacent always includes diagonals. In Murdoku, the default is edge-sharing unless the clue context suggests otherwise.
