FallLine

Read the board, plan a drop, and connect four pieces before your opponent does.

Play at your own pace with an offline computer opponent or a friend on the same device. Choose from three computer levels, from spotting an immediate win to searching deeper lines and controlling the center. No account or network match is needed to play.

Each piece falls to the lowest open space in its column. Build a line of four horizontally, vertically, or diagonally while looking for threats you can block. Clear column previews, optional move confirmation, and distinct piece symbols help make every move easy to read.

Practice with 36 tactical boards covering one-move wins, unique defenses, and double threats. Each drill has a specific goal and can be restarted for another attempt.

After a match, review the winning line, browse key moves, and step through the move history. A casual computer match allows one full-round undo. An unfinished board, match records, puzzle progress, and preferences stay on your device.

Adjust legal-column hints, move confirmation, piece patterns, sound feedback, motion, and board accent colors to suit your play. A playable guide introduces gravity drops, the four directions, and draws.
