Products that do what Nonograms – Friends-only puzzle room with replays and leaderboards does
Invite code: hackernews. No email required for signup. My friend group loves playing nonograms and competing against each other, but we always send each other screenshots of the solved game grid and time after the fact. So from the start, I knew I wanted leaderboards, replays, and shareable links. I also added PWA support so it can be added to the home screen on mobile and an offline play mode. No ads, analytics or nonsense, just nonograms. Some other goodies as well such as YouTube-like scrubber and KDE-based visualization in replays.…

Hi HN! I'm the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet. Why? Well, my Wi-Fi is terrible in the bathroom—and that's where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction. So I built OffChess. OffChess is an iPhone/Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in…

I had the concept in my head for some time and firstly just prototyped it using only HTML & CSS. Sent it to a few friends and they liked it so I made it into its own website and added few 'competitive' features like click counter and share button.

I’ve been working on a puzzle game for a few years as a side project. The game is based on a small region of tiles in a grid that is mirrored, modified, and mirrored again. It’s based on a novel phenomenon I noticed where, once these mutations happen a few times, the original region can be hard to recognize. You have a feeling there are symmetries in the image, but they are just out of grasp. Going further, if only part of the region is visible, such as mirroring off the edge of the board, it adds to the feeling and it becomes a satisfying puzzle to solve. I originally published this on the…

It's like a mix between Picross (Nonograms) and Polyominoes. It's a minimalist puzzler which has no text, no tutorials (none required) and no ads set in a relaxing environment. App Store: https://itunes.apple.com/gb/app/shapeuku-shape-puzzle-game/i... Play Store: https://play.google.com/store/apps/details?id=com.dtbgames.s... I have a bulk load of Android promo codes to give away, so if you'd like one let me know! (Sorry iOS users, I have no free codes left!)

I like small puzzle games to play on my mobile, (because you can put them away easily as well). But I got really annoyed that a lot of them force feed you advertisements. To counter this I made my own puzzle game, as a progressive web app. This means you can install it on your mobile or desktop as an application, and play offline. After the game is offline ready, no requests should be outgoing except checking for updates of the game. So there is no tracking/reporting going on. This also means I rely on old fashion email to get feedback! The game is build in React + Typescript + Vite,…

I posted a version of this over a year ago but decided to rebuild it recently. Bored Spreadsheet is a collection of quick and easy games that look like a spreadsheet from a distance. I have tightened the app to be a collection of 6 games: Minesweeper, 2048, solitaire, sudoku, a market trading game and a daily reconciliation puzzle where the player must find bad data in a fake table. The games are free to play but sign up is required to submit your scores to the leaderboard. As was the original intention over a year ago, I hope this proves useful to those office workers who have a lot of…

Got tired of my debates with my friend's ending in "I'm right bc I said so" so I made a platform where you can debate with your friend's(or a bot, recently added feature) about whatever you want, and after the debate is done a LLM judges who's more sound in logic. Gain points and climb the leaderboard! Feedback and criticism would be appreciated(there's a discord in there if you wanna talk more in depth) p.s.: I decided to use google acc sign in since it makes the whole thing easier to manage(live chatroom feature, etc.). I don't actually do anything with your emails

Hi Hacker News! My friend and I [1] would like to share with you something we did this week-end. We really like the idea of game jams like the Ludum Dare, and we’d like to participate, but it’s often complicated for us, as we are often limited by the rules inherent to this kind of competition: we have to be available at specific dates, and the rules doesn’t always work for us. For example: if you want to participate as a team in a Ludum Dare compo, you have 72h instead of 48h, and you are not required to publish your code. We realized that what we really like is: - To work together. - The…
