Statement

This is a port from the board game Yavalath

  The Goal

The goal of the game is to make a line of 4 without making a line of 3 beforehand.
Click here or here for more detailed rules.

  Rules

Grid:
Game is played on an hex grid. Grid size will always remain the same.

The grid coordinates are represented in the image below:



Resolution of a turn:

A bot must output the coordinates of the hexagon that he wants to play. Once the output is done, the hexagon at those coordinates will be filled.


Output

If the coordinates:
  • Are outside of Hex grid, the game will end and the other player will win.
  • Are inside but the hexagon at those coordinates is already filled, the game will end and the other player will win (exception if is player 2 first turn, see expert rules).
  • If those coordinates result in a line of 4, then the player win.
  • If those coordinates result in a line of 3, then the other player win.

  Expert Rules

On player 2 first turn, he has a choice to either play normally or to replace opponent first move with his own(steal player 1 first move), this will replace the hexagon color by your color.

  Examples

What is a line

The image below shows all possible directions that you can make a line:

  • Red line: Represents a line of 4
  • Green line: Represents a line of 3
  • Blue line: Represents a line of 2
  • Black line: Represents a line of 3
  • Pink line: Represents a line of 4
  • Yellow line: Represents a line of 4
What is a winning move

The image below shows how to win a game:

  • (2,2): Creates a line of 4 { (0,0), (1,1), (2,2), (3,3) }
  • (4,2): Creates a line of 4 { (4,3), (4,2), (4,1), (4,0) }
  • (5,3): Creates a line of 5 { (3,3), (4,3), (5,3), (6,3), (7,3) }
  • (5,4): Creates a line of 4 { (3,2), (4,3), (5,4), (5,5) }
  • (4,4): Creates a line of 4 { (4,3), (4,4), (3,5), (2,6) }
  • (2,3): Creates a line of 4 { (4,3), (3,3), (2,3), (1,3) } and also creates a line of 3 { (2,3), (2,4), (1,5) } but, since both lines were made one same turn the player wins.
What is a losing move

The image below shows how to lose a game:

  • (2,3): Creates a line of 3 { (2,3), (3,3), (4,3) }
  • (2,2): Creates a line of 3 { (2,2), (3,3), (4,4) }
  • (4,2): Creates a line of 3 { (4,2), (4,3), (4,4) }
  • (4,5): Creates a line of 3 { (3,3), (4,4), (4,5) }
  • (3,4): Creates a line of 3 { (3,3), (3,4), (2,5) }
  • (0,6): Plays a move on occupied cell, the other player wins.
What is a steal

On player 2 first turn, he has the opportunity to play on the square the opponent played, and be the owner of it, the image below shows this:

  • (4,4): First player plays on (4,4)
  • (4,4): Second decides to steal his move and also plays on (4,4)

Victory Conditions
  • Make a line of 4 or 5 before making a line of 3 beforehand.
Loss Conditions
  • Make a line of 3 hexes of same color.
  • You do not respond in time or output an unrecognized command.

  Game Input

Initial input
First line: The id of the player(myId)
Input for one game turn
First line: count: the number of rows on hex grid.
Next count lines: characters representing one line of your grid, top to bottom. (0: empty, 1: yours, 2: opponent).
Next opponentX: the x coordinate of opponent move (-1 on first turn for first player).
Next opponentY: the y coordinate of opponent move (-1 on first turn for first player).
Output
A single line containing the coordinates you want to play. Example "4 4".
You can also print messages by doing the following. Example: "4 4 This is a message/This is another message". The "/" will create a new line between messages.
