The game "Atom Five in Row" is a modern twist on the classic Tic‑Tac‑Toe concept, expanded to a 10x10 grid where the objective is to align five of your marks in a row, column, or diagonal. Players compete against a strategic AI that actively blocks and creates its own sequences, offering a challenging single‑player experience. The clean, minimalist interface features smooth animations, subtle hover effects, and distinct colors for player (X) and computer (O). Wins are highlighted with a gentle pulse animation, and a persistent score tracker keeps the competitive spirit alive across multiple rounds.
