Blast Line

Hold the screen to fly your bomb through rocky caves and blast open a path to the exit. Even when a run ends, your past bombs fly again in their recorded sequence and timing, carving open the way ahead! ◆ Team Up with Past Bombs in a Time-Loop Flight Puzzle Never give up when the exit seems out of reach. In Blast Line, returning to the start after hitting an obstacle does not waste your effort. Past bombs launch in the exact sequence and intervals they were recorded. As earlier bombs blast dirt and rock to open a passage, your current bomb glides through the gap to push deeper into the cave. Flying along trails your earlier bombs opened gives you a satisfying feeling of teamwork. ◆ Hold to Rise, Release to Sink: Intuitive Controls No virtual joysticks needed. Touch and hold anywhere on the screen to fly up, and release to sink down. Quick, light taps keep your height steady so you can slip through narrow rock gaps. Enjoy comfortable one-handed play anytime. Prefer tapping? Turn on Tap mode in Settings to switch between rising and sinking with each tap. ◆ Varied Cavern Terrain: Dirt, Rock, Gray Walls, and TNT Caverns are packed with blocks that test your flight precision. Soft dirt crumbles on impact, while hard rocks need multiple blasts to break. Indestructible gray granite walls cannot be blasted, so you must carefully adjust your height to steer around them. Hitting red TNT triggers a chain explosion that clears surrounding blocks at once. Plan your route around TNT to open wide shortcuts. ◆ 50 Cave Levels and Bosses Every 10 Levels Explore 50 cavern stages across 5 zones (Zone 1 to Zone 5), each featuring new layouts and tighter tunnels. Face unique boss stages every 10 levels: Level 10 Cave Guardian, Level 20 Powder Lord, Level 30 Twin Cracks, Level 40 Iron Heart, and Level 50 Cave Overlord. Clear levels in fewer runs to earn more stars, collecting up to 150 stars across the map. ◆ Daily Challenge: A New Map Every Day Play the Daily Challenge, where everyone gets the same new map each day. These fresh layouts test your route planning. Retry as often as you like during the day to find the cleanest path. Clear the map in fewer runs to secure 3 stars for the day. ◆ Smooth Speed-Up Through Cleared Corridors No waiting through sections you have already opened. The bomb automatically accelerates through safe, cleared paths, then smoothly returns to normal speed right before reaching new territory so you can resume precise steering. ◆ Tips for Common Situations - Ceiling collision: Holding too long climbs too fast. Release or tap lightly to steady your height. - Ground fall: Releasing too long causes the bomb to sink. Tap in short bursts to recover. - Gray walls: Gray granite cannot be blasted. Fly around them through open gaps. - Blocked paths: Follow the route your past bombs blasted rather than trying to clear everything at once. ◆ Fair and Privacy-Conscious Experience - No account registration or sign-in required. - Game progress (stars, levels, Daily Challenge history) and sound settings are saved only on your local device. - No banner ads.
