Reveal all safe grid cells by studying the number hints along the top and left headers. Numbers indicate consecutive blocks of safe tiles that appear in that row or column in order. Multiple numbers mean there is at least one mine separating those safe cell blocks. Left click or tap a square to uncover a safe space while avoiding hidden dangerous mines. Right click or hold to place a warning marker on cells you suspect contain explosives. Complete the puzzle by uncovering every safe square without triggering a single mine. Use logical reasoning to analyze row and column intersections to clear all levels safely.
