Hex: A single hexagon in a hexagonal grid.179

Hexagonal/ Hex Grid: The hexagonal pattern laid over a map to facilitate unit movement, measuring
distance, and providing location of units.180

Hex Side: One of the six sides of the hexagon. Sometimes rivers, ridge lines, fortifications or some
other feature run along the hex side. This means the gamer must pay attention to the differences in types
of hex sides as well as different hexes.181

Hex Number: In many games, a four-digit number that describes the row the hex is in (first two digits)
and the hex in that row (second two digits). It is printed in the hex. It was developed by Arnold
Hendricks (while he was working for wargame publisher SPI in the early 1970s) and later released to the
public domain for any game publisher who wanted to use it (many do). A variant of the older letternumber
hex identification system.182

Higher Authority: Designated Controllers, who act as commands and organizations outside of game
play and they make decisions and provide policy guidance to the players as required to maintain game
play and keep the game focused on the objectives. Higher Authority is normally part of Control and is
used by the Game Director to direct game play; however, some games may require the cell to be part of
the game play instead of game control. (Also called Higher Headquarters (HHQ), National Command
Authority, etc.) 183

Hotwash: “the act of reviewing any operations (in particular, a wargame). A hotwash is so named
because it occurs as quickly as possible after the conclusion of the move or game (while it’s still “hot”).184
Note: In large or complex games, the Game Director and game staff, often conduct a hotwash each day.

Hybrid or Mixed Format Game:
• A game that has both open and closed components.185 (See Open Game, Closed Game, and Three
Map Problem)
• A wargame that use multiple adjudication methods, i.e. stochastic for combat outcomes,
BOGSAT (adjudication thru judgment) for diplomatic outcomes.186
