Gunjin Shogi, also known internationally as the strategy board game Stratego, is a game of hidden pieces and strategic deduction. Players battle without knowing their opponent's piece placements, deducing their opponent's strategy based on captured pieces. The objective is to capture your opponent's headquarters. Losing your headquarters to the opponent results in defeat.
