What this teaches
Name the board sizes and how a phone player marks a mine, and the game sets up each one.
- "beginner, intermediate and expert boards" asks for the three classic sizes: 9 by 9, 16 by 16 and 30 by 16.
- "a flag-mode button so it works on my phone" replaces the right-click a phone does not have.
- The change asked for a safe first tap the game already had; the best times per board are what it added.
Changes
Never let the first tap hit a mine, and keep my best time per difficulty.Change request · V1 → V2
What changed
- The best time is kept for each difficulty.
- The first tap was already safe in V1, so that half of the request changed nothing.
What stayed: The three boards, the timer and flag mode work as before.

Known limitations
- The best times are kept in this browser only.
- The expert board is wide and needs scrolling on a phone.
- Each move redraws the board, so a keyboard player's focus leaves the grid after every reveal or flag.
- Flagging and unflagging a square before the first tap counts as a win.
- After a loss, wrongly placed flags still look like flags.
