create multiplayer apps that you can play with friends or share with coworkers. Like Slido/Kahoot but you can create your own one with AI. It can build polls, quizzes or games. had this idea for a while, the space isn't new and there is apps like Kahoot that presenters or educators use for polling/quizzes. however the templates are limited, so I decided to ship my own vibe-coding IDE for generating these. you just describe it for example "noise meter: people scream at their phon

新开发了一款网页小游戏-象棋(卧底版)-支持好友在线联机对战。  游戏网址: https://gameplayer2.com/xiangqi 规则如下: - 胜利条件和普通象棋一样:将死对方的将就算赢。 - 开局时,帅和士都公开明旗。其余 13 枚棋子盖住并重新打乱,其中混入 3 枚对方棋子作为卧底。 - 暗子还没翻开时,先听从它所在的一方。轮到你时,可以走一步棋,也可以用这一回合把自己控制的一枚暗子原地翻开。 - 所有暗子在翻开前都可以横走、竖走,每次最多 3 格,而且不能越过其他棋子。 - 暗子移动后还是暗子。只有它吃子、被吃,或者你主动选择翻开时,才会露出真正的棋子和颜色。 - 吃暗子时,如果吃子方也是暗子,两枚棋子会翻开再完成吃子。 - 如果翻出来的是对方棋子,它会立刻归对方控制。 - 翻开以后,棋子恢复原本的走法。 - 被将军时,可以用暗子挡

An FPS game built as a parent-friendly alternative to Roblox.

I'm a father of two, 7 and 12. They are obsessed with Roblox, especially Rivals. Like a lot of parents, we did not love it. We tried the usual things: block it, limit it, set timers." It became a daily battle, a lose-lose situation. So I flipped the problem. Instead of fighting what they loved, I decided to lean into it, but with a twist. Why just play an FPS when you could build one together? My kids became the PMs. Claude and I became their engineer. I was shocked by how fast we moved. We picked a name, Cooked and started building. Get in. Lock in. Get cooked! In the first 3 hours, we had an actual FPS we could play together in the browser. Next day I invited my friend's two kids over. Suddenly, I had four PMs. We had 3 laptops, 1 iPad and 1 iPhone. So in 30mins we added mobile support and could play all 5 together. The kids would ask for features: "Can we have a rocket launcher that knocks people off the map?" "The knife should stab faster when you hold it." I know al

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.

A rhythm game where you distinguish fake instructions and follow real ones to the beat using arrow keys.
