Landmines is a modern name for a game which I used to know as Battle of the Atlantic or Minesweepers.
A largish clear space is needed for the best game. In this space scatter as many tennis balls as possible - the game works best if the floor has a good covering of them. Players are paired up - one is blindfolded. The seeing player must then navigate his partner ("ship") from one side of the room to the other, through the barrage of mines, using shouted directions only. Teams take it in turn and times are recorded. If a "ship" touches a "mine" then the watching players shout BANG and the team have a time penalty added. If the "ship" touches 5 mines then it is sunk. Fastest team wins.
