After that I just go through all possible piece/location combinations, placing the first puzzle piece in the top position and continuing down. It has 10 pieces that can be flipped/rotated and placed on a calendar. They claim there is a solution for each day/month/weekday combination. In the YouTube video Drew is struggling and says: The below leaderboard updates every 10 minutes (manual refresh required). If you’re having issues, try a force refresh (shift+F5) To solve this, I first encoded all the puzzle pieces, this is relatively easy to do because it’s just a 2D grid. When you solve the puzzle, don’t share the passcode in any channels, let other people enjoy solving the puzzles in their own time. However, you can help guide new agents on the right path.

We are so excited to have “A-Puzzle-A-Day” available for you. This is one of the most fun and addicting puzzles we’ve ever offered. There is a different challenge for every single day of the year. That’s 365 puzzles for one low price, making “A-Puzzle-A-Day” one of the greatest values you’ll ever find.

A-Puzzle-A-Day makes a great gift for your friends, family, coworkers and yourself! Warning! This puzzle is highly addictive! Description The original daily calendar puzzle with 365+ challenges for every day of the year! Now available in 6 languages! I found this puzzle the other week by Dragonfjord called A Puzzle Day. Basically you fit the pieces into a Tetris board but leave the current Mon and Day open. Since I also just bought a laser cutter, I thought I could program a solver for this puzzle and use that program to help me make new puzzles. The very first optimized brute force version of my program took about 8 minutes to find all solutions for a single day. After playing with pypy and multiprocessing I was able to get it down to about 2 minutes. That would still have taken well over 12 hours to find all solutions for every day. Eventually, I was lead down an interesting path of learning what Dancing Links and Algorithm X were and trying to wrap my head around it. I was finally able to get my program to find all solutions for all days in a little under 7m. In the end, I finished the program and ran some numbers that some of you might find interesting.

Next we consider a flipped piece a new solution only if it has a new shape. Symmetrical pieces can then only be placed in 4 orientations and the asymmetrical pieces can still be placed in 8 orientations.Most passcodes are more than likely fully redeemed already however the correct passcode will still work in the form below for this challenge. After 25 hours, the country for that puzzle will be revealed, then 25 hours after that, the city will be revealed.
