理の理 (Ri no ri, Logic and Psychology)

理の理' (Ri no ri, Logic and Psychology) is a card-drafting game for two players. The title is derived from two kanji words: 論理 (logic) which means in this game you can win by precise deduction, and 心理 (psychology) which means in this game you can win by bluffing as well. So the title implies this is a game of deduction vs. bluffing. A round consists of two phases: mustering phase and battle phase. During the mustering phase, players draft revealed soldier cards to form their hand of five cards each. A battle phase consists of five battles. During a battle, the attacker places a card face-down from their hand. The backside of the placed card has partial information about the soldier's identity. The defender looks at it, and places a card from their hand. Then they reveal both cards. A soldier card has its soldier type and power value printed on it. If both players have played a soldier of the same type, the soldier with the lower value wins the battle. Otherwise one with the higher value wins the battle, but some types get a bonus power against a certain type. A new round begins after the fifth battle. When a plyer has won total of six battles, that player immediately wins the game. Players know the identity of some cards their opponent has drafted, and the partial information is printed on backside of each card, which means defender can predict which card attacker has played. But there's some chance of attacker's bluff if carefully drafted. You should consider your opponent's intention to win the game. user summary ラウンドの前半では場に公開されているカードを順番に獲得して自分の手札を構築し、後半では１枚ずつ使用することで相手と勝負を行います。 各ラウンド５回勝負を行い、先に一定数の勝利をおさめることでゲームに勝利します。 カードごとの相性による修正や同種衝突による強弱逆転によりどのカードをいつ使うかの判断が、またカードウラ面により一部情報がわかるのでそれを元に最適解を見つける要素があります。 publisher's summary
