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

Stack towers by dropping floors, with each building based on real architecture.

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.
