Unless you've never used a computer before, this game shouldn't offer you any challenges you haven't met before. This is a very faithful copy of the Minesweeper games distributed with Windows since ages ago.

The game board is made with small images arranged in a table (generated with document.write, but Shep started development way back in 1997 so please excuse the somewhat old-fashioned approach). The game plays very nicely nevertheless, and it feels very much like the real Windows game.
