通过AI分析图片来猜单词的Wordpeek游戏。
furyofantares · HN
Small games. One thing is I have it doing a LOT of visual verification of its results, which uses a lot of tokens. I also tend to throw some huge tasks it can't do yet and watch it burn a zillion tokens, and I usually learn more about where it's limits are and am sometimes happily surprised by its success or partial success. I'll infodump though. I built https://wordpeek.app https://scramble-quest.app and https://playsilhouette.app this year. Those are what I've shipped anyway, a number of other

在线对战隐藏棋子的象棋游戏,支持好友实时多人联机。
lanyi96 · V2EX
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

SparkGap:交互式线性代数导师,求解矩阵问题并获得实时 AI 反馈。
u/CarefulArmadillo3496 · Reddit
SparkGap - an agentic linear algebra experience Hey everyone, I'm building sparkgap.ai , an interactive tutor for linear algebra. You fill in the matrices/vectors, the LLM gives you hints until you get it correct. The hope is that it will get smarter over time from the context of which questions were missed/answered correctly. As you master concepts, the progress ring next to each concept will slowly fill in. Hopefully it should be very difficult to get to full mastery. Feedback and qu
