Sengoku is a turn-based strategy game set in sixteenth-century Japan, written for Kalgoorlie Retro Gaming. You lead one of 28 clans in the 1560 or 1582 scenario. Each province has a governor and up to seven samurai, each with his own abilities, body points and men, and you appoint one for every order: govern your provinces or delegate them to governors, raise and train soldiers, trade at the market, recruit ronin and your rivals' samurai, make marriages, alliances, threats and tribute, and send spies and assassins against your rivals. Marriages tie the clans, envoys come to you with tribute and alliances, and a governor left to rule alone may serve you well or rebel. Invade a neighbouring province and you fight the battle yourself on a hex field, every officer leading his own unit through the days and nights of the battle. Hold all 38 provinces to win.

It has the same retro look as The Broken Seal: a sixteen-colour screen, portraits for every lord and governor, and its own music.

The current version is 1.7.0 (7 November 2026).

The two editions have the same rules, screens, music and save format. The browser edition is a port of the desktop's Free Pascal code to TypeScript, and both run the same self-test; a battle fought from the same start comes out the same in both. Export and Import move a campaign between the two editions as a save file: see Saves.

The same help is in the game: 9 Other > How to play on the main screen.
