User summary:
Pirates Code is a game of deduction and bluffing. There are 14 cards, each numbered 1 through 14, and 12 of them are dealt to players evenly. The remaining 2 cards compose a cipher of the treasure cache. A player wins the game by specifying the correct numbers of these 2 cards.

Each card has its own ability to help gain some clues about the treasure cache. But using the ability comes with a risk of revealing clues to other players. Players have to weigh the risk and the benefit when playing a card.

When a player is sure they have enough clues, it's time for them to declare the codes. The player wins if they are correct. If another player says they have one of the declared numbers, the declaration fails. The declared player misses one turn, but they don't get eliminated, and at least they gain a clue that another player has one. Therefore players may declare codes without enough clues, and experienced players will find out other benefits from early declaration.

「パイレーツコード」は推理とブラフのゲームです。
1～14の番号が書かれた14枚のカードのうち、12枚をプレイヤーに均等に配ります。残った2枚は財宝の隠し場所を示す暗号となります。この2枚の番号を正しく言い当てたプレイヤーが勝者です。
カードにはそれぞれ独自の効果があり、財宝の隠し場所に関する手がかりが得られます。しかし、それには相手に手がかりを与えるリスクも付きまといます。カードを使用する際は、このリスクとリターンを測る必要があります。
十分な手がかりを得られたと確信したら、暗号を宣言します。その暗号が正しければ勝利します。正しくなくても1ターンを費やすだけで、脱落はしません。そのため、実は十分な手がかりがなくても宣言することができますし、熟練者はこの宣言を他の目的で使うことを思いつくでしょう。
