Follow meaning alone to reach the hidden word first.
Read the constellation of meaning on the radar.
Duel vs AI, online, or a nearby device. One-time unlock.
Reach the hidden word before your opponent — using nothing but how CLOSE your guesses are in meaning. A fresh kind of word-guessing duel.
Type any word and see its HEAT (0–100): how semantically close it is to the hidden target. The nearer the radar's centre, the hotter. Related words link up into a living "constellation of meaning." Follow the heat, read the connections, and close in.
