Murdoku puzzle craze spikes as guide urges recycling of schoolbooks

The hybrid puzzle known as Murdoku – a blend of sudoku logic and Cluedo mystery – has become a summer bestseller. Commentators note that “people are completely hooked and it is selling massively,” and the format is praised for being suitable for solo brain‑exercise or group play.

At the same time, a practical guide advises families on handling textbooks after the school year. It stresses reusing books that are still in good condition, donating usable copies, and only recycling when materials are damaged. The guide outlines how to separate paper, cardboard covers, plastic laminates and metal or plastic bindings to ensure proper recycling.
