Play gravity-drop four in a row in focused, offline matches. Choose a local computer opponent or pass the same device between two players. Read the board before every drop. Preview a column's landing space, connect four pieces horizontally, vertically, or diagonally, and block an opponent's open lane. Three local difficulty levels offer relaxed play, direct threat defense, and deeper positional choices. Build your instincts with 36 tactical drills across three goals: find a one-move win, make the unique defense, or create a double threat. Each drill gives you a clear objective and can be restarted at any time. An interactive guide demonstrates gravity, winning lines, defense, and draws. During a match, pause and resume, review the move list, or undo one complete turn in a solo game. After a match, inspect the winning line and replay each drop step by step. Track results by computer difficulty, fastest wins, and completed drills. Choose drop confirmation, legal-column hints, piece symbols, move sounds, reduced motion, and a light or dark board. Match progress and preferences are stored on your device.
