Everything you need to go from your first puzzle to 6x6 Hard.
Logic grid puzzles reward a handful of habits more than raw cleverness. These guides teach those habits in order. Each one builds on the last, and they all use real Logic Dogs clue wording, so what you read here matches what you'll see in the game.
Start here. How the grid works, the two moves that solve most puzzles, a worked 4x4 example from first clue to finished grid, and the mistakes nearly every beginner makes.
A reference for all the clues in the game, from “at the Park” to knight's moves and equidistant clues: what each one means, what it rules out, and when it becomes useful.
For 6x6 Hard puzzles: location scans, linked pairs, locked pairs, chaining relative clues, and contradiction testing, plus a checklist for when you're stuck.
For teachers and parents: what logic grids teach, which level to start with, a 30-minute lesson plan, discussion questions, and ideas for students who need more support or more challenge.
Free worksheets: ten puzzles per pack, easiest first, each on its own page with a scratch grid, plus an answer key at the end.
Practice with real puzzles. Every past daily puzzle has its clues written out, a step-by-step walkthrough naming the clue behind each deduction, and the final answer.
