How to Play Tunnel Explorer

Click / tap tunnels to reveal them. Numbers indicate how many traps lie in the adjacent 8 squares. Discover all signal towers (glowing icons) hidden within the grid. Safely uncover tiles to form connected paths between towers. Use SONAR (3 uses per level) to instantly reveal a large safe zone. Right-click / long-press to mark and unmark suspected traps for extra score. Avoid revealing tiles that contain traps—one mistake can end the expedition.
