Board game played by players and its playing method

Abstract

A board game, in which a game can be developed in an unexpected way, includes plural dice selected from among plural dice, which can be unfolded two-dimensionally and are rolled. According to the results of the rolling of the dice, a die is unfolded and placed on the play field. On the unfolded dice a player places his/her piece. Also according to the results of the rolling of the dice, a player saves costs necessary for pursuing a game on an Addition/Deduction Unit. On the cards respectively corresponding to pieces, the Group, Level, Ability, etc., of the pieces are indicated. A player makes his/her piece advance or attack the opponent's piece by paying the saved costs, and at the same time makes his/her piece defend itself by paying the saved costs as well. A player, who succeeds in giving predetermined damage to a specific piece of the opponent, wins a game.
