Logic Grid Puzzles


Instructions

Read the clues, then use the grid to mark what is possible and what can be ruled out. Tap a square to cycle between blank, ✗, and ✓ as you build your deductions. When you know a match is certain, marking it helps you eliminate the other possibilities and uncover the next clue.


Every puzzle has exactly one solution and can be solved through deduction—no guessing required. When you're ready, press Check Answer to see if you've cracked the case.

Introduction

Logic Grid Puzzles is a free educational math game that challenges students to solve deduction puzzles using clues, logic, and mathematical reasoning. Instead of solving equations or answering a list of problems, students use a grid to rule out possibilities and figure out exactly how everything fits together. The clues use real middle school math, including fractions, angles, rates, percents, scale factors, and integers.
