This interactive word search puzzle presents a 15×15 grid of letters with 15 hidden words to find. Players click and drag across adjacent letters to highlight words horizontally, vertically, or diagonally; correctly selected words are marked as found with a color change in both the grid and the word list. The code uses plain DOM manipulation with `getElementById`, `createElement`, and `querySelector` to build and update the grid. Word placement uses randomized logic with collision checking, while mouse events (`mousedown`, `mouseenter`, `mouseup`) drive the selection mechanism. A New Game button regenerates the puzzle with a fresh random layout.
