做了个反应速度测试站， 5 个工具+17 个小游戏，求各位帮忙看看 前段时间看了个小游戏站赚美元的教程，想着自己也试试手。没搞太复杂的——先做了几个认知测试工具，又嵌了些免费小游戏，搭了个站。 地址：checkreaction.com ( https://checkreaction.com/ ) 目前有这些： - 反应速度测试，5 轮取平均，带年龄基准对比 - 瞄准训练，30 个随机目标，测速度和精度 - 打字速度，30 秒 WPM - 序列记忆、数字记忆两个记忆测试 - 17 个 iframe 小游戏，纸牌、台球、消消乐、Cut The Rope 这些 技术跟 FH6Wiki 一样简陋——纯静态 HTML + 原生 JS ，扔 Cloudflare Pages 上。反应测试就一个 4.5KB 的单文件，也扔 GitHub 开源了。 为啥做这个 顺手查了下关键词难度。"reaction time game" KD 只有 4.8/100 ，排第二的是个 DR=0 、8 个月的新站，体验分只有 22 。第六名是个床垫公司。Google 甚至拿 Red
