The minefield scrolls down past the red line into the black out-of-bounds strip. Once a row has slid all the way in, every mine in that row has to be flagged 🚩: an unflagged mine goes off and the run is over. You can't click inside the strip, but a row that's only partway in can still be played through the part of it that's above the line.
Flags have to be right: a 🚩 on a safe tile that goes out of bounds also ends the run, so you can't just flag everything. Dig safe tiles to reveal numbers, same as classic: a number counts the mines in its eight neighbours, including the rows above and below. Digging a mine ends the run too. You get one life.
The bottom rows start open, so there's something to read right away. The field starts moving on your first dig or flag, and it speeds up (and gets denser) the longer you last. Your score is how many rows you get past the line.
Mouse: left-click digs, right-click flags, click a finished number to chord. Touch: tap digs, long-press flags (or switch to 🚩 Tap flags). Keyboard: ←↑↓→ move, Space/Enter digs, F flags, N restarts, P pauses.
