Replay board keeps this exact mine layout and hides everything again — so the first click is no longer protected, because you have already seen the board. Clear Saved deletes the saved game for this difficulty and deals a new one.

The largest board here: 30×20 with 130 mines. It scales the grid rather than the density, so this is a longer solve at Expert-level pressure — not a board that forces more guesses. That is 22% of the grid mined.
Quick Tips for Master
- Pace yourself; this is a board you finish by not making one careless click.
- Resolve each front fully before moving on, or you will re-derive it later.
- Use flag mode on touch — 130 long-presses is a lot of waiting.
