Logiquiz offers daily self-referential logic puzzles where the clues describe the solution grid itself. Players deduce the contents of a grid, typically numbers or symbols, based on statements about the grid's rows, columns, and other properties. Each puzzle has a unique solution, achievable through logical deduction without guessing. The website provides a new puzzle every day, along with an archive of past puzzles.
The Hacker News post titled "Show HN: Logiquiz – Daily Self-Referential Puzzles" introduces a website, Logiquiz.com, dedicated to providing a unique form of logic puzzle. These puzzles, presented daily, are characterized by their self-referential nature, meaning the clues within the puzzle often refer to the structure or content of the puzzle itself. This introduces a layer of meta-analysis where solvers must consider not only the logical relationships presented, but also how those relationships relate to the puzzle's own form. Logiquiz challenges users to deduce the correct answers to a set of questions, typically presented in a grid format, based on clues that intertwine with the puzzle's layout and numbering system. The website offers a fresh puzzle each day, providing a continuous source of mental stimulation for enthusiasts of logical deduction and wordplay. The self-referential aspect adds a significant degree of complexity and intrigue, differentiating Logiquiz from traditional logic puzzles like Sudoku or KenKen. The site likely aims to cultivate a community of puzzle solvers who appreciate this particular style of cerebral challenge, offering a daily dose of intricate, self-aware, and satisfyingly solvable puzzles.

HN users generally found Logiquiz an interesting and enjoyable puzzle concept. Several appreciated the self-referential nature and the clean presentation. Some expressed concern about the limited number of puzzles currently available, while others offered suggestions like adding difficulty levels, hints, and the ability to share solutions. One commenter suggested adding the capability to generate puzzles, possibly leading to user-created content. The potential for puzzle variations, like Sudoku-style constraints, was also discussed. A few users drew comparisons to other logic puzzles, such as "Knights and Knaves" and existing grid-based logic puzzles.
The Hacker News post for Logiquiz, a site featuring daily self-referential logic puzzles, generated a moderate amount of discussion with 17 comments. Several commenters expressed their appreciation for the puzzle format, finding it enjoyable and a good mental exercise. One commenter mentioned a similarity to the "Knights and Knaves" type puzzles, where one must deduce truth from statements made by individuals who either always tell the truth or always lie. This comparison highlights the core logic element at play in Logiquiz puzzles.
Another commenter praised the puzzles' elegance and simplicity, emphasizing their self-contained nature where all the information necessary for the solution is present within the puzzle itself. They appreciated that no external knowledge is required. A different user echoed this sentiment by highlighting the satisfying "click" moment when the solution becomes apparent. This suggests the puzzles offer a rewarding sense of accomplishment upon successful completion.
One commenter requested a feature for users to input their answers directly, allowing for immediate feedback and a more interactive experience. This suggests a desire for a more gamified version of the current presentation. Another user offered specific suggestions for enhancing user experience such as the inclusion of a timer and a difficulty rating system. These comments indicate users are engaged with the concept and are thinking about ways to improve the platform.
One thread of discussion explored the mathematical and computational complexity aspects of the puzzles. Commenters discussed whether the puzzles belong to the NP-complete complexity class and touched upon strategies like constraint satisfaction and binary decision diagrams as potential solving approaches. This suggests that while the puzzles appear simple on the surface, they offer a depth that can engage those interested in computational theory.
Finally, a few comments simply expressed enjoyment or stated intentions to try the puzzles later. Overall, the comments reflect a generally positive reception to Logiquiz, praising its engaging and mentally stimulating nature, while also offering constructive feedback for potential improvements.
