The competitive aspect of jigsaw puzzling dates back to the 1980s in the US, when Hallmark ran a national competition for several years. In 2022, the volunteer-run USA Jigsaw Puzzle Association partnered with Ravensburger to bring back a national championship.

The Financial Times puzzle by the setter known locally as Harpo, navigating to Independent 12,318 by the solver known locally as Enigmatist and our own Paul here at the Guardian, continues to impress.

The news of the AI's medal win was published by thousands of media outlets and chosen as one of the year's biggest scientific breakthroughs by the journal Science. And this is where the story starts to get complicated. Because the news is a lie.

"It's definitely a conversation starter," said Snyder, a three-time world Sudoku champion and an author and editor of more than dozens of ebooks such as 'The Art of Sudoku' and 'The Art of Puzzles.'"

With its Alpha series of game-playing AIs, Google's DeepMind group seemed to have found a way for its AIs to tackle any game, mastering games like chess and by repeatedly playing itself during training. But then some odd things happened as people started identifying Go positions that would lose against relative newcomers to the game but easily defeat a similar Go-playing AI.

Which Algorithm Is This? If you step back, this maps almost perfectly to the Top K Frequent Elements problem.We usually solve it for integers in a list. Here, the "elements" are audience profiles age and body-type combinations. First, define what an audience profile looks like: case class Profile(age: Int, height: Int, weight: Int) What we want is a function like this:

The day Josh Wardle sold Wordle to the New York Times, in 2022, for more than a million dollars, should have been a moment of triumph. The game, which gives players six chances to guess a five-letter word, had unexpectedly become a global sensation, and Wardle had already begun to receive e-mails from puzzle designers seeking his input on their own ideas.

A real Tetris loop has time (ticks), concurrent inputs (keystrokes), state transitions (collision, locking, line clears), and non-determinism (piece generation). In many imperative designs, these concerns end up tangled in shared mutable state, which tends to produce bugs that are: hard to reproduce (timing-dependent), hard to test (logic mixed with effects), hard to debug (replay isn't deterministic).

This week's puzzle was constructed by Rebecca Goldstein and Kelsey Dixon, and edited by Hoang-Kim Vu. Rebecca is a crossword constructor from the Bay Area, and Kelsey is a crossword constructor from Chicago. They both lived in Atlanta in the '90s, which is why Kelsey has been trying to start a rumor that Rebecca was her childhood babysitter. They hope you don't take the puzzle too seriously!

It may seem like they've been around forever, but the crossword as we know it is barely a century old. They started in the New York World in 1913, where it was originally called a "word-cross." Going on to obsess writers like T.S. Eliot and Vladimir Nabokov, who reportedly wrote the first Russian-language puzzle as a teenager, the crossword settled into a kind of urbane normalcy over the course of the 20th century, a feature of newspapers and cheap jumbo packs.

Walking through a field one day, a 17-year-old schoolteacher named George Boole had a vision. His head was full of abstract mathematics - ideas about how to use algebra to solve complex calculus problems. Suddenly, he was struck with a flash of insight: that thought itself might be expressed in algebraic form. Boole was born on November 2, 1815, at four o'clock in the afternoon, in Lincoln, England.

MicroMacro: The Home Game Jigsaw Puzzle is a 500-piece puzzle that utilizes the same art style as all other MicroMacro titles. The puzzle depicts a socc....errrrr, a football game, as well as the neighborhood surrounding the stadium. It is "just" a puzzle; however, there is more to it after you complete it. There are forty-two hidden objects to find (think Where's Waldo?), as well as two cases to solve, like other MicroMacro games.

This time he led early, had a wobble with three draws and a loss, but was strong in the final two rounds. It was a long way for me, he said. I was very close every time and I failed year after year. I'm extremely happy to finally be able to win this tournament and to win in a very nice style.
