The nine-by-nine Classic board contains ten mines. Reveal every safe square to win, and read each number as a count of adjacent mines, including diagonals. For a first round, focus on explaining one next move rather than trying to finish the entire grid quickly.
Loading the board…
Reveal every safe cell. Each number counts mines in its eight neighboring cells, including diagonals. Classic has a 9 × 9 board and ten mines; Practice has a 6 × 6 board and five mines. Your first cell and its neighbors are safe. On a phone, select Flag before marking a suspected mine; on a computer, right-click. A flag is an assumption until the clues prove it. Some boards can require guessing.
A nine-by-nine board has 81 squares. Ten contain mines and the remaining 71 are safe. The winning condition is to uncover those safe squares. A flag helps you mark a location you believe contains a mine, but placing ten flags does not independently prove a win.
The smaller Practice mode has six rows, six columns, and five mines. It uses the same neighbor-count rules, so it can help you become familiar with the controls. Choosing a smaller board is not a promise that every later decision will be obvious or that a round will end inside a particular break length. Return to Classic when you want the nine-by-nine problem, not because finishing Practice unlocks another rule.
An interior square touches eight positions: above, below, left, right, and four diagonals. A corner has only three neighbors and a non-corner edge has five. The number reports mines in that exact neighborhood. It does not refer to the whole row, tell you a direction, or count flags as true simply because you placed them.
Try reading one exposed clue aloud. A 1 with three unresolved neighbors means exactly one mine remains among those positions if there are no other adjacent proven mines. It does not tell you which of the three to open. Listing the possibilities is a valid start; selecting one without another constraint is not yet a deduction.
The game places mines after your first reveal, outside that square and its neighbors. A zero can open a connected safe region automatically. The numbered border of that region gives you clues to inspect, so a large opening does not require repeatedly tapping every square inside it.
Safe-first-click protection does not make Classic a no-guess generator. The accepted random board can later present uncertainty. Avoid translating the size of the opening into confidence about its next covered neighbor. Instead, look for a boundary clue with only a few unresolved positions, or compare two clues that share most of their neighbors.
If a 1 has exactly one unresolved neighbor and no mine already accounted for, that neighbor must contain a mine. Now consider another 1 touching that same proven mine. Its remaining covered neighbors are safe because its mine requirement has already been satisfied. This pair of steps can open a new area without choosing randomly.
The second step relies on the first flag being justified. If you guessed the first location, you cannot count it as proved evidence in the next clue. Keep your assumptions separate from your deductions. On a phone, also confirm whether the current tool is flagging or revealing before touching the intended square; using the wrong tool can make a sound argument produce the wrong on-screen action.
You can stop with part of the board unresolved. Pause and return to the visible clues rather than restarting merely because the next move takes thought. Local progress depends on storage remaining available in the same browser; it is not a cross-device account or a shared online game.
Before leaving, identify what remains uncertain: perhaps two positions satisfy the same 1, or a flag lacks a clear reason. That is more informative than remembering only the remaining-mine counter. When you resume, verify those notes against the numbers before opening another square. Learning the distinction between a demonstrated safe move, a plausible guess, and an accidental input is a concrete improvement in how you read this board, even when the round does not end in a win.
The main nine-by-nine Classic board has ten mines and 71 safe squares.
Yes. A clue counts mines in all touching squares, including diagonal neighbors inside the board.
No. Winning requires revealing every safe square, and flags can be wrong.
No. It protects the opening, not every later decision in a Classic layout.
Yes. Practice uses a six-by-six board with five mines and the same clue rules.
