I made a multi-player (up to 12 players) Scrabble-like game. Everyone submits their turn at the same time so there are no long waits between turns. It's a "capture territory with words" game.
The capturing territory part reminds me of Truncate which I absolutely love (and absolutely hate the UI): https://news.ycombinator.com/item?id=39882873 -> https://github.com/TruncateGame/Truncate (MIT)
Even if it does exist, it may not use the "Scrabble" trademark, making it difficult to search for. For example, one time I forgot what Woogles was called and had trouble finding it again since it doesn't mention Scrabble at any point. I had to use an LLM to remind myself what it was called.
Everyone should follow Will Anderson, he runs an extremely high quality Youtube channel -> https://www.youtube.com/@wanderer15
Even if you don't play often, his scrabble videos are fantastic to watch on a lunch break.

My friends and I are playing around with vibe coding a 4+ multi player scrabble, surprisingly it doesn't really exist. (hasbro is extremely tight on their copyright)
