A web-based word search puzzle presents a 15x15 grid of letters with hidden seasonal and color-themed words. The game uses the Canvas-free approach of DOM manipulation with `document.createElement` and event listeners for `mousedown`, `mouseenter`, and `mouseup` to enable highlighting word selections. A custom grid generation algorithm places words randomly in horizontal, vertical, or diagonal directions, then fills empty cells with random letters. The interface displays a word list and a "New Game" button, with visual feedback through CSS classes for highlights and found words.
