The Toughest Developer Puzzle Ever

There was a bit of a leak on the interwebs this weekend, and many people are now aware of a little project I’m putting together that I’m calling the Toughest Developer Puzzle Ever. Each level exists as a web page, and the challenge is to figure out how to get to the next level. To do this, users will have to use ALL of the information available to them. It’s not all coding tasks, but it plays on the knowledge of someone who works in the software world.

Some of the puzzles might have you debugging Javascript, others might require you to recognize a font and translate it. The idea is that it’s going to require a broad range of knowledge and problem solving skills.

How Do I Get Started?

The initial levels of the puzzle can be found at We have put together about 35 levels so far, and are working with others to get this puzzle over 100 levels. If you have questions, we also have a Twitter account set up for this: TDPE

How Can I Contribute?

Contact me, Jeff Blankenburg, directly at I’m looking for challenging puzzles in the vein of the ones currently up on the site, but I’m always open to innovation and new challenges.

Your puzzles will be hosted on your website, and we’re expecting the traffic from this puzzle to also help drive traffic to your website.

  1. how come at level 24 it tells you to go to a certain page after entering the correct answer, but then the page doesn't exist?

  2. I would love to see something like an RSS feed or email notification on the “stop” page, so I know when new puzzles are added. :)J.Ja

  3. Hey Jeff,Possibly a stupid question but I’m going to go for it anyway. Is the temporary stop around puzzle 8 or 9 another puzzle or is it actually a temporary stop as you finish the other 25 or so puzzles?Kevin
