This interactive word search puzzle displays a 15x15 grid of letters with 15 programming-related terms hidden horizontally, vertically, or diagonally. Players click and drag across the grid to select letter sequences, with valid words receiving permanent green highlighting and appearing crossed off in the word list. The JavaScript implementation uses DOM manipulation and event listeners for mouse interactions, while CSS grid layout structures the puzzle board. A "New Game" button regenerates the puzzle with randomly placed words and fills remaining cells with random letters.
