Fun idea! I am glad there seems to be a community of people enjoying word games on HN, it tends to be the first place I post my games. https://squareword.org (wordle meets sudoku) and https://clickword.org (scrabble meets tetris... ish) are the largest so far.

I think https://videopuzzle.org has a lot of potential also, but it targets an audience that's a bit different as it is more visual, focused on reassembling videos like a puzzle.

Will post these to the arcade! :)
