Put your students’ detective skills to work with this FREE set of 3 mystery grid-based logic puzzles, featuring Sudoku- and Star Battle-style deduction!

Students use clues, deduction and elimination to work out where each character belongs on the map. There can be only one character in each row and each column, so every clue helps narrow down the possibilities. Once everyone is correctly placed, students use the completed map to solve the final mystery.

This sampler introduces the puzzle format gradually, progressing from a 6×6 grid to 7×7 and 8×8 grids.

Three mini mysteries included:

Mystery 1: Who Pranked Portia? – a 6×6 school mystery

Mystery 2: The Camp Cookie Caper – a 7×7 outdoor adventure

Mystery 3: Where Is Max? – an 8×8 missing-puppy playground mystery

Students will practice logical reasoning, deduction, spatial awareness, following multi-step clues and eliminating impossible answers while solving each case.

The resource includes:

3 printable logic puzzles • How-to-solve instructions • Quick clue guide • Full solution pages

Perfect for Grades 4–6 / ages 9–12, including:

early finishers • morning work • logic centers • enrichment • indoor recess • sub plans • brain breaks • gifted and talented activities

All puzzles are black-and-white and printer friendly.

Start with the 6×6 mystery, then see if your young detectives can work their way up to the 8×8 challenge!
