Four modes of gameplay:
• Classic minesweeper – the game we all know and love
• Open edges helps you avoid hitting a mine with your first click
• Blocking terrain increases the challenge by preventing you from looking at some squares
• In Infinite lives mode, you don't loose the game when you hit a mine, you just get a time penalty in your score — perfect for all those times you accidentally click the wrong square!
• The optional full-screen mode makes it easier on your eyes
