Are you ready to sell your soul—literally—for the good of the nation? In 'I made a contract with the devil for the sake of my country, and it turned out to be a big deal!!', you step into the shoes of a party leader in a world where the supernatural is as real as an empty campaign promise. Your goal is simple yet perilous: win a four-week election campaign to become the next great leader. But don't think it's just about making pretty speeches; to win public support, you'll need financial power, military might, and intelligence.

The core gameplay revolves around a classic trick-taking mechanic, but with a chaotic twist. While the game uses three main suits for standard play, the real drama unfolds when you tap into 'forbidden power.' There are special suits: the Devil and the Priest. Playing a Devil card allows you to overpower almost any standard play to win the trick, but watch out! If an opponent is clever enough to play a Priest card in the same trick, the divine power nullifies the demonic pact, and the Priest takes the win. It's a high-stakes game of cat and mouse where you must manage your hand to fulfill the contracts you accepted at the start of each round.

Beyond winning tricks to collect crystals, your primary focus must be meeting your specific contract goals. Ultimately, the player who best balances influence, strength, and a bit of devilish cunning to hit their contract targets will be crowned the winner. It's fast, it's tense, and above all, it's a political struggle where nobody is truly a saint!
