Dozenal – A Game of Spatial Arithmetic

u/eashish93 · Reddit

I made a tower stacking game where every height you pass is a real building highrise.lol - tap to drop a floor, stack it as high as you can. Every height you pass is a real building. Free, no signup. Built with Claude Opus 5. Three things I got wrong. I thought the game was the hard part. It wasn't. Anyone can POST a fake score, so I rebuilt the physics to let the server replay your whole run from a seed and a list of taps and check it itself. That touched everything.

A couple weeks ago we were on vacation with friends, and after the kids were asleep we played games -- mostly Qwirkle, which I had never played and am terrible at. I don't care about being terrible at games, so I made a web version to keep playing after vacation: build lines of tiles that share a color or a shape, 2-4 players (or add bots). I wanted it to be low friction, so there are no accounts. Your identity is an anonymous id in localStorage, and you can move it to another device by scanning a QR code or hitting a unique url. Start a game and text someone the link (game slugs are semi-memorable three word phrases), or "Play the computer" and you can play immediately against bots. Games are async-friendly with web push for turn notifications. The stack is one Node process on a small VM, Next.js + Socket.IO, no database. The server and the client use the same engine so moves validate optimistically, and the bots go through the same functions, so bot moves are always legal. State is

made a fun little website with AI to explain how the Oceans in FFIX are authored after days of slamming my head against the keyboard trying to deconstruct it

做了一个完全在浏览器本地处理的图片拼接工具： MergeImage 最近做了一个免费图片拼接工具 **MergeImage**： https://mergeimage.app/ 起因很简单：临时把截图、商品图或前后对比图合成一张时，很多在线工具需要先把原图上传到服务器，或者在导出时加水印。我想做一个打开就能用、处理边界也更清楚的小工具。 目前支持： - 最多添加 30 张 PNG 、JPEG 或 WebP - 横向、纵向、网格，以及连续截图的智能重叠拼接 - 拖拽排序、旋转、翻转、间距、背景和尺寸对齐 - 预览后导出 PNG 、JPEG 或 WebP - 图片解码、排版和编码都在当前浏览器本地完成，不需要注册，也不会添加水印 智能拼接会保守判断重复区域；如果置信度不够，会保留完整图片并退回普通纵向拼接，避免误删内容。 现在还是 MVP ，桌面端和移动端都可以直接用，也做了中文界面。欢迎试用，尤其想听听大家对长截图、网格排版和大图性能的反馈。
