About Minesweeper
Classic minesweeper on a Sundered floor: Field 9×9, Vault 16×16, Deep 30×16. The first stone always opens a region, and every layout can be finished by reading the numbers.
No pre-generated bank — a fresh floor after every New. Field, Vault and Deep are the three classics; Custom picks any size up to 30×16 (or a square that fits the same 480 cells). A best time per combination, no names.
How to play
- Goal
- Open every stone that hides no charge.
- How it ends
- You win when every safe stone is open; opening a charge ends the game at once.
- Record
- The fastest first clear of each floor, with its holder's name.
- Open every safe stone. A number is how many charges touch it.
- The first stone is always safe. Mark charges, then clear the rest.

Tips
- Start from the zeros. A blank opening already tells you every neighbour of those stones is safe.
- Finish a number. If a 2 already has two flags, the rest of its neighbours are safe — tap the 2 to open them.
- Count the leftover charges. When the counter matches the covered stones you can see, they are all charges.

Questions
Can the first click hit a charge?
No. The floor is built after that click, and the stone you chose is always a blank opening.
Will I have to guess?
No. A layout is thrown away unless a logic solver can finish it from that opening.
Are the boards the same for everyone?
No — each New lays a fresh floor. The record is the best time for that size and charge count, not for one particular layout.
Can I pick my own size?
Yes. Custom goes from 5×5 up to 30×16, or any square that fits in 480 cells, with as many charges as still leave an opening.
Is my progress saved?
Yes, in this browser. An unfinished floor comes back when you press Continue.
