About

Block Line

Features
Read full description

Block Line is a turn-based block strategy puzzle game. Place shared blocks on the board, protect your own cells, and try to claim more space than the computer. When a row or column is filled, the line clears, so every move can help you or remove the blocks you wanted to keep. Choose 4-cell, 3-cell, and 2-cell blocks carefully. If no move is available, use your one-time chance to cut one cell from a block and keep the game going. Simple rules, strategic choices, and quick matches make Block Line easy to start and fun to replay.
