KDice is a browser-based multiplayer strategy game based on Taro Ito's Dice Wars. KDice is programmed in Adobe Flash and AJAX by Ryan Dewsbury and was released in 2006. Gameplay in KDice is a simplified version of Risk with the primary goal of the game being to control every territory on the map.
To attack, a territory containing more than one die is selected, and a target, which must be an adjacent territory held by an opponent, is then selected. The game then rolls a number of dice equal to the sizes of the dice stacks on the two territories and compares the totals. If the attacking player has a higher total, he takes control of the territory under attack; all but one of the dice from the attacking territory are then moved to the defeated territory. Otherwise (if the attacker's total is equal to or less than the defender's), the attacker does not gain control and the number of dice in his stack is reduced to one. Players can attack multiple times per turn, limited only by the number of their dice remaining. At the end of the turn, the player receives a number of dice equal to the largest number of contiguous territories he controls. These are added randomly throughout the player's territories. The maximum number of dice allowed on each territory is eight. Surplus dice (up to 32) are stored if all territories have 8 dice; the game uses these to restack the territories where possible. In contrast to Risk and similar games, dice may not be moved between territories, so forethought and strategic play are required when deciding where to attack.
In August 2007, a new system was put into testing that threw out the algorithm for ELO and ranked players using points accumulated starting from 0. From September 1, 2007 to January 1, 2008, varying implementations of this new system were used where players contributed points to a "pot" every turn and redistributed them according to number of territories held. This led to the birth of a strategy called "point-farming", an unpopular practice where the player in first place would drag the game out as long as possible to keep farming points out of the other players who were jockeying for place amongst each other. The update pushed out on January 2, 2008 was designed to do away with this practice -- in a race that has basically been decided the player in first place will not be awarded extra points for extending the length of the game.
