The prompt

Make a Minesweeper-style game in one HTML file. Three sizes; place mines only after the first tap so it is always safe and opens an area; flood-fill empty areas; flag with long-press or right-click; tap a satisfied number to open its neighbours. Count mines left, time the game and keep best times. On a phone, turn the wide Expert field upright so the squares stay tappable.

Claude wrote this game from a short brief like this one. It was then played, tested on phones and tuned before it went up here.

How to play

Each number tells you how many of the 8 squares around it hide a mine.
Flag the squares you are sure are mines, and dig the rest.
Your first tap is always safe.
Clear every safe square to win.
