The freeware game Combat Engineer is basically a remake of Minesweeper, but
with some things of its own.

The playfield consists of 33×19 cells and one bomb in each corner. The primary
goal of the game is to defuse those bombs before your time runs out. This is
simply done by clicking on the corner cells, however, unlike Minesweeper ,
you can’t just click any cells, but only adjacent ones to already opened ones
(you start with 3×3 opened ones in the center). So you have to make your way
to all four corners.

Like Minesweeper , each cell contains a number from 0 (blank) to 7, telling
how many mines are in adjacent cells. So you have to think which ones you
simply open and which ones you mark as a mine. If you trigger one or two
mines, the game does not end, because you are a bit protected, however the
third mine will kill you.

The game comes with 4 difficulty settings (Easy, Medium, Hard, Very Hard),
which impact on how dense the minefield will be.
