Empire Tide

Each lead gives you clues about where and when the trail leads. The twist: a city may have belonged to a different empire in the target year than it does today, so you must read the empire clue against the year you pick. Catch the culprit by choosing the right city and the right year across every lead.

• Read the case-file clues for the current lead
• Pick the city you think the trail points to
• Pick the year, the ruling empire depends on it
• Commit your guess; nail both city and year to catch the culprit

• Desktop: click a city and a year, then click Track the Culprit
• Phone & tablet: tap a city, tap a year, then tap to commit

• If a clue names an empire, find the city-and-year combination where that empire actually ruled
• Right city but wrong year still loses the trail, treat the date as half the answer
• Easy, Medium and Hard widen the map and the span of years you must consider

Empire Tide is a geography-and-history deduction game about shifting borders and the rise and fall of empires across the ages.

• Skills: world history, empires, historical geography, change over time
• Best for: roughly grades 6–11 (ages 11–16)
• For parents & teachers: how empires rose, shifted and fell.

Following clues to a city while remembering that it may have belonged to a different empire in the target year than it does today is historical geography rather than modern geography.

Making the year part of the question is the original twist.

That is the correction most map knowledge needs. Borders are recent almost everywhere, and a place's name, ruler and language can each have changed within a century — so "where is it" and "whose was it" are separate questions with separate answers.

Empire Tide is an original geography-and-history deduction game built around shifting borders and the rise and fall of empires. Play free in your browser with daily and practice chases.
