In this game, capturing your opponent's pieces makes their remaining pieces more powerful.
 
Each player begins with four pieces. On his move, a player may move one of his pieces n spaces, where n varies depending on the number of pieces she has remaining:
Four pieces remaining: one space per turn
Three pieces remaining: two spaces per turn
Two pieces remaining: three spaces per turn
One piece remaining: four spaces per turn.
 
A piece may capture an opposing piece by moving onto it. If a piece makes a capture before it has used all of the spaces available to it that move, it may continue to make additional captures until it has moved its limit. A piece may move over intervening pieces. The player who captures all of his opponent's pieces wins.
 
In the Ist variant, a piece may move n spaces in any combination of diagonal or orthogonal directions.
In the IInd variant, pieces may move n spaces in any combination of orthogonal directions.
In the hex variant, pieces may move n spaces in any combination of hexagonal directions.
The three variants above each have a 'free' variation, in which your pieces start off the board. Each turn a player may either place a piece or move a piece that is already on the board.
