Murdle books in order

Begin with the three numbered volumes, then choose a spin-off or junior title. Publication order is not a promise that every regional edition is already on sale. Check the ISBN and publisher date before ordering.

The official market page describes the series as a number-one Sunday Times, USA Today, and Amazon bestseller. These are the source's historical claims, not a current chart ranking. Announced titles are separate from released editions; check publication dates in your region.

Wiki lists disagree about which book is 'fifth'. I follow the publisher counts above and I say so when a printing detail is edition-specific.

Questions and answers

How many Murdle books are there?

Three numbered volumes of 100, plus spin-offs (School of Mystery, Seven Skulls, Heist, Jr., and others). A single number such as 6 or 9 usually forgets a shelf.

Do I need to read them in order?

Each grid stands alone. Reading in publication order preserves the running character story; Volume 1 provides the introductory tutorial.
