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.

做了一个免费的 Concrete Calculator，帮 DIY 用户估算混凝土用量 最近做了一个英文站：The Concrete Calculator 地址： https://the-concrete-calculator.com 它主要解决一个很具体的问题：用户在做 patio 、shed base 、walkway 、slab 这类小型混凝土项目时，不知道该 买多少混凝土、多少袋，或者该订多少 cubic yards 。 目前支持： - Concrete Slab Calculator - Concrete Pad Calculator - Concrete Yard Calculator - Concrete Bag Calculator - waste factor - cubic yards / cubic feet / cubic meters - 简单材料成本估算 做这个站的原因是我发现很多英文混凝土计算器要么广告太重，要么结果不够直观。这个版本尽量把核心计算和 单
