DropLine

Drop pieces into a 7 by 6 board and connect four horizontally, vertically, or diagonally. Each piece falls to the lowest open space in its column, so every move can open a threat or close one. Play a focused solo match against three local rule-based opponents, or pass the same device between two players. Preview a landing spot before confirming a move, watch full columns become unavailable, and review the winning line when a match ends. Build your tactics with 36 short challenges across three goals: find a one-move win, make the only defense, or create a double threat. Completed challenges and quickest finishes are tracked on your device. Unfinished matches can be resumed later. Solo games allow one undo of a complete turn, while challenge boards can be restarted for another attempt. Move replay helps you review the sequence, and the guide includes an interactive practice board. Choose piece patterns, legal-column hints, move confirmation, motion, sound, and a dimmed color palette in Preferences. Two-player games, solo matches, and practice boards work offline. Game boards, preferences, and records stay in local device storage; no account or network connection is needed to play.
