A territory comes with a number of dice. When it is a player's turn, - she marks one of her territories as a launching pad for an attack at a - neigboring territory of the other player. Such an attack is enabled only if - her chosen territory has more dice than the territory of the other player. - The effect of the attack is that the territory changes ownership and that all - but one of the attack dice are moved to the newly conquered territory. A - player may continue her turn as long as she can launch attacks. Optionally, - she may choose to pass after her first attack is executed, meaning she ends - her turn. At the end of a turn, a number of dices are distributed across the - players' territories. The game is over when a player whose turn it is cannot - attack on her first move. - - A player can use the following five keys to play the game: - -- with ← and → (arrow keys), the player changes the territory focus - -- with enter, the player marks a territory the launching pad for an attack - -- with the "d" key, the player unmarks a territory - -- with the "p" key the player passes. - Once a player passes, the game announces whose turn it is next. - - Play - ---- - - Run and evaluate - (roll-the-dice) - This will pop up a window that the game board, and instructions. -|# - -(require 2htdp/image (except-in 2htdp/universe left right)) - -;
