Gruzzler
The Game

Gruzzler is a unique puzzle game that challenges your logical thinking, optimization, and problem-solving skills.

Unlike traditional number puzzles, in Gruzzler you must discover the clues yourself.

When you're done you can share your clues!

Please play, my degree is in bioinformatics.

How To Play

RulesEvery grid

  • Each number appears once per column
  • Each number appears once per row
  • Each number appears once per house

CluesSelf-setting

Gruzzler is a self-setting puzzle — there are no clues until you ask for one. Select a cell, then select a number: the clue lands in that cell and reports on that number. You choose where your clues go and which numbers they are about.

Single
Double
Target
Every clue points along the row or column, never diagonally. Single — one arrow to the nearest. Double — two arrows, equal distance either way. Target — the number belongs in this very cell.

ModesThree pencils

Search Discover clues by entering numbers in cells
Scratch Eliminate impossible numbers from cells
Solve Place your final answers to complete the puzzle

SizesThree boards

6×6
8×8
9×9
Houses hold as many cells as the board is wide. The 8×8 is irregular — its houses interlock, and each puzzle draws one of thirty-six tilings.
The Origin

During the pandemic, I started watching a lot of Cracking The Cryptic. One day, I fell asleep during a Simon solve and had a fever dream about puzzles. I dreamt of Sudoku where you discovered all the clues.

I asked one of my game-design friends if he thought he could make the puzzle game I was dreaming about.

We worked through prototypes. I'd suggest a change, he found ways to make it work, back and forth until we had a really fun playable game. When I wasn't working on my dissertation, I was working on what eventually became Gruzzler.

It's my favorite creation. I hope it brings you satisfaction and joy.
