Crossonym

Crossonym is a daily word game built on synonyms. You're given the day's word — FALTER, SERENE, DUSTY — and a grid of blanks where one synonym crosses it at each letter. Type a letter and it fills every synonym at once, so each guess is a bet across the whole board. Three mistakes ends it. It's been running daily since April, with a standard and a hard grid every day (hard trades FUMBLE and STUMBLE for VACILLATE and QUAVER), plus a full archive of past puzzles. The reason it's worth a look: nearly every daily word game since Wordle has been a spelling or grouping puzzle. Crossonym is about meaning — it's the only one I know of on the web where the whole game is synonyms.
