The game is set in Japan during the Sengoku or "Warring States" period. Each player assumes the role of a great Daimyo with troops. Each Daimyo has the same ten possible actions to develop a kingdom and secure points. To do so, the Daimyo must deploy armies with great skill. Each round, the players decide which of the actions are to be played out and in which of their provinces. If battle ensues between opposing armies, the unique Cubetower plays the leading role. The troops from both sides are thrown in together and the cubes that fall out at the bottom show who has won immediately. Owning provinces, temples, theaters and castles means points when scores are tallied. Whichever Daimyo accumulates the greatest number of points after the second tally becomes shogun and wins the game.
