Queen Guard app for iPhone and iPad

Queens Guard (or Agon) is a strategy game for two players, played on a 6x6 hexagonal gameboard.
It may be the oldest board game played on a hexagonally-celled board, first appearing in France as early as the late eighteenth century.
The game reached its greatest popularity a century later when the Victorians embraced it for its blend of simple rules and complex strategy.

Rules

Each player has one queen and six guards. Black player moves first, then move turns alternate. A circle below the game board always indicates the color of the move turn. On each turn, a player moves one of his pieces.

The object of the game is to be first to maneuver ones queen to the central blue cell (the throne) at the center of the board, and surround her with all six of her guards.

Moves

The game board may be thought of as a series of concentric rings of hex cells (highlighted by rings of alternating colors).
Pieces move one step at a time to an adjacent cell, either sideways in the same ring, or towards the throne to the next ring.
The cell moved to must be vacant. Only the queen may move to the throne.

Captures

A piece is captured when two enemy pieces are on adjacent sides of it, in a straight line.
The player whose piece is captured must use his next move turn to relocate the captured piece at its starting position.
Relocation is automatically executed by application.

Other rules

If a player surrounds an empty throne with his guards, then neither player will be able to form the winning configuration, and that player forfeits the game.
It is not allowed to move a piece between and adjacent to two enemy pieces, in a straight line.

Restart

When the game ends, a new game starts automatically. But, if you want to begin a new game before the current one ends, just touch the Restart button.
