Games::Risk - classical 'risk' board game


version 4.000


Risk is a strategic turn-based board game. Players control armies, with which they attempt to capture territories from other players. The goal of the game is to control all the territories (conquer the world) through the elimination of the other players. Using area movement, Risk ignores realistic limitations, such as the vast size of the world, and the logistics of long campaigns.

This distribution implements a graphical interface for this game.

Games::Risk itself tracks everything needed for a risk game. It is also used as a heap for Games::Risk::Controller POE session.




Start the application, with an initial batch of @modules to build.


    my @modules = Games::Risk->maps;

Return a list of module names under Games::Risk::Map namespace.



  • my $game = Games::Risk->new

    Create a new risk game. No params needed. Note: this class implements a singleton scheme.


The following accessors (acting as mutators, ie getters and setters) are available for Games::Risk objects:

  • armies()

    armies left to be placed.

  • map()

    the current Games::Risk::Map object of the game.

Public methods

  • $game->cards_reset;

    Put back all cards given to players to the deck.

  • $game->destroy;

    Break all circular references in $game, to reclaim all objects referenced.

  • $game->player_lost( $player )

    Remove $player from the list of active players.

  • my $player = $game->player_next()

    Return the next player to play, or undef if the turn is over. Of course, players that have lost will never be returned.

  • my @players = $game->players()

    Return the Games::Risk::Player objects of the current game. Note that some of those players may have already lost.

  • my @players = $game->players_active;

    Return the list of active players (Games::Risk::Player objects).

  • $game->players_reset( @players )

    Remove all players, and replace them by @players.

  • $game->players_reset_turn()

    Mark all players to be in "turn to do", effectively marking them as still in play. Typically called during initial army placing, or real game start.

  • $game->send_to_all($event, @params)

    Send $event (with @params) to all players.

  • $game->send_to_one($player, $event, @params)

    Send $event (with @params) to one $player.


This is a work in progress. While there are steady improvements, here's a rough list (with no order implied whatsoever) of what you can expect in the future for Games::Risk:

  • screen to customize the new game to be played - DONE - 1.1.0

  • config save / restore

  • saving / loading game

  • network play

  • maps theming

  • i18n - DONE - 3.101370: gui, 3.112590: maps

  • better ais - DONE - 0.5.0: blitzkrieg ai, 0.5.1: hegemon ai

  • country cards - DONE - 0.6.0

  • continents bonus - DONE - 0.3.3

  • continents bonus localized

  • statistics

  • prettier map coloring

  • missions

  • remove all the FIXMEs in the code :-)

  • do-or-die mode (slanning's request) - DONE - 1.1.2

  • "attack trip" planning (slanning's request)

  • other...

However, the game is already totally playable by now: reinforcements, continent bonus, country cards, different artificial intelligences... Therefore, version 1.0.0 has been released with those basic requirements. Except new features soon!


Please report any bugs or feature requests to bug-games-risk at, or through the web interface at I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.


I definitely recommend you to buy a risk board game and play with friends, you'll have an exciting time - much more than with this poor electronic copy.
