The world is a small map with 12 territories, each containing a castle. Surrounding the land portion of the map is an ocean perimeter. The land part of the world gets divided up among the players and everyone gets an equal number of castles. The object of the game is to take over everyone else's castles using your armies. You can attack any castle if it is immediately adjacent to one of your castles. After capturing a castle you get to draw a loot card which gives you gold. Use the gold to buy more armies or to buy a ship which you can use to transport armies to attack castles that aren't immediately adjacent to your already conqured land.
To Attack a castle there are two phases. The External Battle and the Internal Battle. The external battle by land can be either a Direct Attack or a Sneak Attack.
The Direct Attack is the only time you directly face-off against an opponent using the Odyssey. The duel is simply this: The Attacker sends the BallSpot across the screen at the highest speed possible, and attempts to wiggle it, using ENGLISH, past the Defender who can only use their Vertical Control to block it. It IS a bit more challenging then, say, Tennis or Football, because of the high speed of the BallSpot. Really, the game is mostly on the game board and in this case, the video component is used when dice or even Rock, Paper, Scissors would have sufficed.
