Very Easy — logic-grid deduction puzzle
Spilled cleaning fluid has smudged the village clinic's register, and the staff need help working out who came when, and why.
Every patient who visits the village clinic gets written into the big register on the front desk. On this busy morning, the first four names in it were Otto, Rosamund, Barnaby and Cordelia. Then the nurse, hurrying back to the treatment room, knocked over a bottle of cleaning fluid. It ran right across the open page, and the ink blurred into blue puddles. Now nobody can read who came when, or what they came for. The staff each remember a few bits of the morning. Can you help them put it back together?
Read the clues, rule out what cannot be, and prove what must be. Every GRIDIGMA puzzle is verified by a solver that shows the reasoning behind each step, so a solution is never a guess.
