Medium — logic-grid deduction puzzle
Use the helper's quick notes to find out who collected from each peg, and which color and mask each customer took home.
It was the night of the big masked ball, and the little rental stand was buzzing. Four customers came to pick up the outfits they had hired: Paloma, Niall, Zsofia and Adeel. The outfits hung on a row of four pegs along the wall, each with a small number tag, from number one by the door to number four at the far end. Each outfit was a different bright color, and each had a mask clipped to it with its own painted shape. The stand was so busy that the helper only had time to scribble a few quick notes about who took what. Now someone has to sort it all out.
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.
