A downloadable puzzlebook

Lineon is a book of paper-and-pen puzzles for one player or a cooperative group by Blaz Urban Gracar.

It separates itself from similar puzzles like Sudoku, Picross or Connect-The-Dots by telling a story. It is a story about lethal chases and frantic battles – about forgiveness and forgetfulness – and about saving a little girl’s life.

All is expressed by drawing lines between points.

Lineon is available as a PDF and as a browser app adaptation.

You can print the PDF and play it on paper: DOWNLOAD

Or you can play the browser app adaptation by Igor Zuber (still using the PDF for rules and story): PLAY

Lineon is a series of puzzles to solve.

You solve puzzles by drawing straight lines between points on the Grid. These lines represent movements of Friends and Regressors. Your main goal is to keep Friends safe - which means you'll need to maneuver them past the deadly Regressors towards the Exit Point.

Lineon is a work in progress. Currently at version 0.7.

Lineon is my attempt at implementing classic platforming style of video games into a paper'n'pen game environment. The possibility of drawing lines in any desirable direction reminds me of the intuitive way how you control and move characters in games like Super MarioCeleste and Cuphead.

The story of saving a little girl's life is closely related to something that's currently happening in my life - so the process of creating the game is also sort of a therapy and a prayer for me.

In the process of making Lineon, I got acquainted with Igor Zuber, a kind soul from Poland and a talented programmer, who ported the game from the book into a web browser app, expanding the Lineon experience. Thank you, Igor!

If you like what you see and play, please support the project by following its development, sharing the word about it and providing feedback! Let's make this game a great one :)

Lineon is also accompanied by a soundtrack.

This is such a neat system. I love how the puzzle solutions feel like a story without the rules being too contrived.

Thank you woofmao! Glad to hear you enjoyed it :)

Are there any plans to finish this at some point, or have you just moved on? Just curious.

I love the system, so I plan to return to it in some form in the future, however, I need to find a way to streamline the rules. But yeah, I really like how the puzzles feel to solve, so I want to return. Can't say when and how.


i just completed the first chapter and i  love it so far <3

Yay, glad to hear it!! :) - Blaz


beautiful little game!

I was wondering if it was possible to have a "puzzles-only" version of the game,

That is to say, a downloadable document with only the puzzles, no explanation, no solution, and maybe two or more puzzles per page? that'd save a lot of paper, don't you think?


Hi Bruno, thank you for your comment! :)

All puzzles are available in the image format on this link: 


You can print them out this way! Let me know if you have any troubles with it.
