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

Complete sentences and get a clanker score based on how predictable you are to AI.
niklio · HN
You write 8 text completions and open models score how predictable each word was too them. Predictable => clanker. You can share results with your friends. The scoring checks every word you write against the model's logprobs. Right now I'm using Llama3.1, Deepseek v3 and Qwen3 to keep costs low. I tried to calibrate it so other models (chatgpt/claude) score 100% and interesting human responses score in the 10-30% range. Totally free, no signup

没写过游戏尝试下，目前对普通人来说，写一个自己的简单小游戏，在开发这块确实已经不是什么困难的事了。 [2048]( https://tinker.liriliri.io/zh/guide/official-games/2048.html)：[在线玩]( https://tinker.liriliri.io/games/2048/)  [扫雷]( https://tinker.liriliri.io/zh/guide/official-games/minesweeper.html)：[在线玩]( https://tinker.liriliri.io/games/minesweeper/)  [蜘蛛纸牌]( https://tinker.liriliri.io/zh/guide/official-games/spider-solitaire.html)：[在线玩]( https://tinker.liriliri.io/games/spider-solitaire/)  [滚石迷宫]( https://tinker.liriliri.io/zh/guide/official-games/ball-maze.html)：[在线玩]( https://tinker.liriliri.io/games/ball-maze/) ![滚石迷宫]( https://raw.githubusercontent.com/liriliri/tinker-games/master/packages/tinker-
