Advanced
Grid: 16 × 30 · Mines: 99 mines
For practicing intermediate and advanced techniques on a big board.
Advanced is a wide 16×30 grid with 99 mines — the same size as the traditional Minesweeper 'Expert' spec. Long wall patterns that span several borders are the key.
Because it follows the traditional rules, a guess may rarely be needed. Hints prioritize cells that logic can confirm, so save them for when you're truly stuck.
- Master wall patterns like 1-2-1 and 1-2-2-1 outright.
- In the late game, cross-check the position with the total remaining mine count.
