This is java version of the classic Parker Brothers RISK board game, with a simple map format, network play, 1 player, hotseat, 5 user interfaces and many more features, it works in all OSs that run java 1.4 or higher. if you've ever played conventional Risk, you already know the basics. However, jRisk adds a couple of additional tweaks to the original game. Notably, the application allows you to play three different types of games: Domination, Capital, and Secret Mission. Unlike conventional Risk, jRisk offers six map views; besides the familiar Continents view, you have Ownership, Border Threat, Card Ownership, Troop Strength, and Connected Empire. These views help you keep tabs on your empire, detect threats, and manage your troops more effectively.
