Show HN: Embedo – Word Equation Puzzle Game

Hello HN, Embedo is a word-equation puzzle game where you guess the solution to expressions like A + B − C. After each guess you see how close your word embedding is to the correct answer, which helps you converge quickly.

Today's puzzle: pasta + noodle − lasagna = ?

I built this for fun. Enjoy!

    Really nice game, thanks for sharing! Can you share which embedding are you using?

    I've tried some on Gemini 2.5 Flash and it can solve them after giving one example.

    fun! thanks for that!

    Consider A/B testing a non-techie alternative without the math or embedding gloss, sort of like analogy-completion, using words: e.g., "What's a pasta with noodles but nothing like lasagna?"

    Part of my attraction to NYTimes Wordle is seeing how I do relative to other users, and how much was luck. In this game I do want to get it right, but I'm also interested in whether others made the same mistake/answer (for this answer, or similarity to others on a series of answers). This social aspect is catnip to game buyers, sites that want to add games to attract users.

    I'd be particularly interested if, after observing my answers, it could start to predict my answers. I'm not sure, though, what UI would enable you to prove the machine made the prediction before I made my choice, without showing the prediction. Maybe display the prediction encrypted and then give the key to decrypt (even just for user keys like a rotation cypher)?

    Fun puzzle. I got the last 4 days in 1 attempt each. The correct answer detection felt a bit slow, and the confetti could be a bit faster.

    I was surprised to get it right in a single guess, without quite being able to describe crisply why I thought that was the answer. It's not really like an SAT analogy problem, which you can reason through repeatedly to gain confidence. Interesting game.

    Really cool! Felt like I had to think the way the AI might. Only took 5 minutes, but totally hooked me

    Nice game. But if this is just for fun please take out those horrible ads

    It seems that it's case sensitive, is that correct?

      It also doesn't trim the input. But very enjoyable nevertheless!
