Copperfield Mines

Copperfield Mines brings classic minesweeper to a warm survey journal. Each field is a nine-by-eleven grid of copper-covered squares. Your task is to open every square that does not contain a mine. Number clues tell you how many mines touch that square, including diagonal neighbors. Fifty numbered surveys gradually increase the mine count from twelve to twenty-one. BEGIN WITH A SAFE PATCH The first square you open, and every square directly surrounding it, are protected from mines. The field is planted when you make that first opening, so a different starting square can produce a different layout within the same survey. An empty opening spreads through connected empty squares and reveals the numbered boundary around them. This gives you a useful place to begin reading the field. OPEN OR FLAG The large mode control beneath the board switches between OPEN and FLAG. In OPEN mode, tap a covered square to reveal it. In FLAG mode, tap to place a flag where you believe a mine is hidden, or tap again to remove that flag. A flagged square cannot be opened until you remove the flag. The counter shows how many flags remain relative to the field's mine total; a flag is a note, not proof that its square contains a mine. READ THE NUMBERS CAREFULLY When an open numbered square has the same number of surrounding flags as its clue, tapping that number opens its unflagged neighbors. This shortcut can speed up a carefully solved area, but an incorrect flag can make it open a real mine. The game does not certify that every generated field can be solved without guessing. Use the visible clues, remember what each flag represents, and decide where to take a risk when the available information is insufficient. FINISH THE SURVEY Opening a mine ends the attempt and reveals the mine locations. Opening all safe squares completes the survey, even if you have not flagged every mine. Retry the same numbered field or return to the survey book to choose another. A FAMILIAR MENU The main screen has Play, Settings, How to Play and Exit.
