Word Space 3D: Player Guide

Find the hidden word by navigating meaning.

How to Play

1. Guess a word — any word
2. Watch where it lands — each word has a position in semantic space
3. Check your temperature — the similarity percentage tells you how close you are
4. Follow the heat — blue is cold, red is hot
5. Find the mystery word — get 100% similarity to win

Reading the Display

The Similarity Score

This is the number that matters. It tells you how semantically close your guess is to the mystery word:

• 0-30%: Cold. You're in the wrong neighborhood.
• 30-60%: Warm. You're in the right general area.
• 60-80%: Hot. You're getting close.
• 80-95%: Very hot. You're circling it.
• 95-99%: Almost there. Think of synonyms.
• 100%: You win.

The Colors

Words change color based on their similarity:

• Blue = cold (far from mystery word)
• Red = hot (close to mystery word)

The Arrows

Arrows point toward the mystery word. They grow longer as you get warmer.

The 3D Positions

Words that appear close together share meaning. If your guess lands near food words, you're in the food region. Use this to orient yourself.

Important: The 3D view is a compressed approximation. When the positions and similarity score disagree, trust the score.

Related Words

Each guess reveals nearby words from our vocabulary:

• They're selected by similarity to YOUR GUESS (what's semantically nearby)
• They're scored by similarity to the MYSTERY WORD (how warm that region is)

Use them as a radar. If all the related words are cold, move on. If they're warming up, explore that neighborhood.

Strategy Tips

1. Start broad — Get a feel for which region of meaning you need
2. Think in clusters — If "dog" is warm, try other animals
3. Use related words — They show you the neighborhood temperature
4. Trust the percentage — It's calculated in full 512D, more accurate than 3D positions
5. Watch for surprises — Synonyms aren't always neighbors; context shapes meaning

Winning

Guess the exact mystery word.

This is harder than it sounds. Unlike Wordle, there are no letter hints. You're navigating purely by meaning. Sometimes words that feel related are semantically distant. Sometimes unexpected words are surprisingly close.

The mystery word changes daily.

Good luck.
