TrioNine

TrioNine is a free English browser word game: sort nine words into three groups of three. It offers hints, category explanations, and easy, medium, and hard practice. No account or download is needed. The shared daily puzzle resets at midnight UTC using a finite 38-board repeating collection. Practice allows replay of that collection. Results can be shared as text or a colored word-group poster with a QR link. Independently published by MORROWCAT LABS, with no affiliation to The New York Times.
