Today’s plate
Timestamp
Five real photographs and prints out of the American record. For each one: what year was it made, and where was it taken? You’ll see how close you got, and what you were looking at.
Free, no login, nothing saved to a server. A new set of five every day.
Teachers: the full version runs all 900+ rounds across every APUSH period with a unit-review mode, student logins, ranks and a class leaderboard, and every guess lands in your Google Sheet.
Read the frame like evidence — clothing, machinery, signage, the photographic process itself.
Slide the year, drop a pin. Both halves score independently, out of 5,000 each.
Every frame is a real public-domain or openly licensed source, credited — no illustrations, no stand-ins.
Click the map to drop your pin. Zoom in for cities.

What today covered
Five plates, one page of review
This is one day of it.
The classroom version runs 900+ rounds across all nine APUSH periods — with a unit-review mode, its own daily challenge, XP and ranks, a field notebook students fill as they discover plates, a class-period leaderboard, and every guess landing in your Google Sheet.
Not buying today? Take a whole simulation instead.
Tell me where to send it and I’ll hand you Cold Case Logic — a complete, classroom-ready simulation, free. Students do the work, and every answer lands in your Google Sheet. Same idea as this game, a full class period long.
