集団陣形棋 (Shudan-Jinkeiki)

集団陣形棋 (Shudan-Jinkeiki) (Troop-Chess) is an abstract game for two players, which can be played using components from other games (such as Go, Chess, Shogi). In Troop-Chess, players organize battle-formations with their pawns and use these formations in both offence and defense.

The game can be played in three versions, each using groyps of three, five or eight pawns. A player can take action only if they have organized a battle-formation using the specified number of pawns.

For this reason, a player who has reduced their pawns to fewer than the specific number, or has divided them too small, making it impossible to organize any formation, will lose the game. It is possible that both players get incapacitated at the same time, because they have reduced their pawns too much simultaneously. In this case, the game ends in draw.

Each type of battle-formation has its own nature, such as strong in attack or highly maneuverable. One formation has only mobility. As well as the predefined formations, you can create original battle-formations as you like. And modify the number of pawns that are used too.

Each pawn does not have any nature by itself, but the power or strength of the formation organized from pawns is affected by its relationship with the neighboring pieces.

What is required to determine this is only a method to judge which are allies or enemies.

Further, whilst in the original game, each pawn has no nature itself, the designer encourages players to customize the game further by introducing specialized pawns. user summary

複数駒で陣形を築き、攻守に役立てる2人用アブストラクトゲーム。 3，5，8駒のバージョンがあり、それぞれの数で規定の陣形を作らねば行動不可能。 ゆえに、自軍の駒が既定の駒数未満に減らされるか、陣形を作れないほど分断された方の負けとなる。場合により、同数駒で双方行動不能となる場合があるが、その場合は引き分け。 陣形により攻撃力が強い、機動力が高いと性格が分かたれている。機動力のみの陣形も。 こちらが用意・提示している以外の陣形を各人が好みで創造することも可能。駒数も自由。 周囲との関係性で陣形の強さが変わるため、駒は無性格。敵味方判別の白黒があればいい。 駒は無性格であるが、発展形として特殊駒を導入するとゲームの深みは格段に増す。 publisher's summary
