A book that is also a game
Murdle was designed to be solved solo, with a pencil and a deduction grid. But every case in G. T. Karber's series has everything a tabletop game needs: characters, a crime, clues and an answer to uncover. With a few simple rules, the mysteries become a family logic game, with no board, no pieces and no setup time. This article suggests three game formats, with age and book recommendations for each. All titles (Portuguese editions) are in the Murdle collection at Loja dos Puzzles.
What you need
Very little. One Murdle volume, a pencil and an eraser per player, blank sheets to copy the grid when several people are playing at the same time and, optionally, a timer. If the table brings together young kids and adults, ideally have a Murdle Júnior for the younger ones and a numbered volume, such as Murdle #1, for everyone else.
Format 1: the detective race
This is the most straightforward format. All players solve the same case at the same time, each on their own grid copied onto a sheet of paper. One player reads the clues aloud, or everyone takes turns reading from the book. The first to announce who did it, with which weapon and where, and get it right, wins the round. Anyone who gets it wrong sits out that round, to discourage random guesses.
Adjusting the difficulty
Since the cases are organized by increasing difficulty, it is easy to balance the table. Choose elementary cases for the first rounds and level up as everyone gains confidence. To give kids an advantage, you can assign them an easier case from the same book or a Murdle Júnior case while the adults tackle an “impossible” one.
Format 2: the cooperative investigation
In this format, the family solves the case together, with a single grid in the middle of the table. Each player reads one clue in turn and proposes the matching mark, a cross or a check, explaining their reasoning. The others confirm or challenge it. The grid is only marked when everyone agrees.
It is the ideal format for kids who are still learning the grid, because they hear the adults putting their deductions into words, and for tough cases, where several heads together will find clue connections that one alone would miss. It is also the most relaxed option for long evenings.
Format 3: the mystery master
Inspired by question-and-answer games. One player takes on the role of master, reads the case and the solution at the back of the book, and does not solve it. The others only have access to the list of suspects, weapons and locations. In turn, each player asks the master for a clue, which the master reads aloud. Instead of asking for a clue, a player can choose to risk a full accusation. If they are right, they win; if they are wrong, they are out of the round. The master role rotates with each case.
A variant with testimonies
In cases where the suspects give statements, the master can read the testimonies only when a player “questions” a specific suspect. This forces players to choose carefully who to ask and brings the experience closer to a real interrogation.
House rules that help
A few rules make the game fairer. Pencil, never pen, so mistakes can be corrected. Nobody marks the grid based on a hunch: every mark must cite the clue that justifies it. The book's hints are only used when the whole table agrees. And the solutions stay closed until the end of the round, so the surprise is not spoiled.
Which books to choose for each table
For families with kids ages 8 to 10, Murdle Júnior #1 and Murdle Júnior #2 have short cases that are perfect for quick rounds. For teens ages 12 and up and adults, any numbered volume works; the more compact Murdle #4 travels well to the grandparents' house. For groups that enjoy visual puzzles, Murdoku allows for parallel placement rounds, and the Murdoku blog has more ideas for playing in a group.
Frequently asked questions
How many people can play?
There is no limit. In the detective race, each player needs a copy of the grid. In the cooperative and mystery master formats, one book is enough for the whole table.
How long does a round take?
An elementary case can be solved in a few minutes. Difficult cases can take half an hour or more, especially in cooperative mode, with each clue discussed.
Can kids keep up with the adults?
From age 8, yes, especially with Murdle Júnior cases or the first cases in each volume. The cooperative format is the most inclusive.
A family evening with pencils, grids and a crime to solve is a simple alternative to screens and the usual board games. Choose the right volumes for your table in the Murdle collection at Loja dos Puzzles (Portuguese edition) and set up the first round.
