Fun! Very similar to https://www.dragonfjord.com/product/a-puzzle-a-day/
So many puzzles like this basically require you to brute-force the solution [0], which just isn’t all that fun. I’m glad the designers explicitly acknowledge they’re trying to avoid this, and really hope that their claim that this actually can be solved with logic holds true:
What if instead of doing the full colored puzzle, we find partial sets of tiles where there is only one unique solution? This adds enough constraints to the problem that it becomes feasible [without resorting to brute force].
A blast from the past! I once wrote an implementation of dancing_links in C++ as part of a Sudoku solver: https://github.com/stlab/adobe_source_libraries/blob/main/ad...
Be careful! There's a whole world of mechanical puzzles out there, and it can get very expensive and start to take over your life.
Here's an assortment of links to places where you can buy interesting puzzles. This isn't exhaustive of course: it's just a few places that came to mind.
Also:
Tavern Puzzles, high quality metal entanglement puzzles:

Craighill. These puzzles are beautiful and double as art objects:
It would be nice, if they could publish the exact cover. I have written some algorithm that can estimate the number of solutions to an exact cover base on the number of solutions it found and the size of the 'tree' that has been explored.
I could write a program myself to calculate the exact cover, but I guess, it will take me about a day to do so. It would not surprise me if the exact cover will be a few hundred mega bytes (when using one character per position).
We haven't actually run the thing to completion. We ran it for a couple days and then stopped after finding tens of thousands of solutions. Might explore again if we have time to improve the solver efficiency.
Reminds me of the 1 million pound first solution prize Eternity puzzle ...
Absolutely love this. Amazing creativity!
Totally feeling like vibe-coding a web version of the game and plastering it with giant BUY THIS THING links that send people to the real thing.
Looks amazing but getting 500 errors from the payment flow and the FLUMMOX discount code doesn't work as advertised.
hi colordrops! the flummox coupon works in the shopping cart. often folks try to apply it in the gift card box in the checkout procedure. Let me know if you already placed and order and I can apply the coupon retroactively for you. If you would like to provide any more info on the checkout errors you can email me at orders@nervo.us
I'm somewhat ignorant about the search ranking implications of changing our domain. I bought the nervo.us domain much later and we've had the n-e-r-v-o-u-s.com domain since 2007.
I paused at the statement "Add $55 for free domestic shipping" on the order form.
Oh my god, take my money, please. These types of tactile puzzles are the ideal nerdsnipe for me.
Recently I designed a calendar puzzle with 10 tetris-like pieces. When you place all the puzzle pieces on the board, three squares/rhombuses are still open and together they form a date. Can you arrange the puzzle pieces in such a way that it shows todays date?
