Nest The Game [iPhone]

NEST - a strategy game for 2 players - remotely resembling chess.
A great bird’s nest is a battlefield. Each player tries to win a fight for the nest by surrounding a small defenseless chick with their various bird soldiers - while trying to protect their own.

How to win?

Victory can only be achieved in one way. You have to surround the enemy’s chicken from all six sides of these hexagons. No matter if it’s surrounded by soldiers of only one team or both - the only important thing is the absolute encirclement on all sides! Which means the immediate victory of a player whose chicken will find at least one free field around itself.

Basic rules
o. Players alternate after each move. You can either cast a new stone or move with already deployed one.
o. The first stone of the starting player belongs to the centre of the battlefield. The first stone of the second player must be placed on the touch of the opponent's first stone.
o. Each newly deployed stone (except the first stone) must only be attached to one's own existing stones and must not touch any opposing ones.
o. Until you deploy the chick (in the third or fourth move), players are only allowed to cast stones, not to move with them. From then on, you can move your stone in one of the ways described below, at your discretion to win the game!
o. All stones must be connected to each other with at least one side, therefore creating a nest. Any move that would violate this rule is not possible (except for one exception - falcon).
