LineAlign is a vertical fantasy minesweeper puzzle mobile game that blends classic logic deduction with a cave‑exploration atmosphere. Players find themselves in a dim mine, facing a grid of interlocking diamond‑shaped crystal tiles. By tapping to reveal unknown areas and long‑pressing to place warning flags, they advance step by step on a 9×9 board. Hidden among the tiles are ten shadow crystals, some of which carry cursed power—mistapping one deducts a significant amount of points. Safe areas are marked with colorful gem clusters indicating the number of adjacent mines, helping players deduce their next move. The game is timed at sixty seconds, keeping the pace tight. Players can also use the "Detection Eye" up to three times to automatically reveal a safe tile, turning the tide in critical moments. Score accumulates based on the number of safe tiles revealed, and successfully avoiding all mines wins the round. The rules are straightforward yet strategically deep, making it easy to pick up in spare moments while still testing observation and on‑the‑spot judgment.
