Line of sight (gaming)

Line of sight, sometimes written line-of-sight, is a term used in wargames and some role playing games (RPGs). It refers to visibility (that is, who can see what) on the playing field.

Often in role playing games, miniature figures are used to determine line of sight. This was often used in games such as Dungeons & Dragons early its history, but the latest version of the game doesn't require their use (except in a special edition just for minis). Many wargames use counters or "chits" to represent units and determine line of sight.

Examples

A tank behind a tall hill would not be able to see an enemy tank on the other side of the hill. Therefore, the first tank does not have a "line of sight" to the enemy tank. Conversely, a squad of soldiers atop the hill may be able to see both tanks, though the tanks may not be able to see them (since tank's upward line of sight is limited).

For another example, a group of adventurers in an RPG may not see monsters located around the corner in a dungeon.
