The 60-second version

1. Look around. Click and drag the panorama to inspect the scene. Wheel to zoom. Click the cyan + markers for short historical factoids.
2. Place a pin. Click anywhere on the map to drop your guess for where this scene happened.
3. Pick a year. Drag the timeline at the bottom. Hold Shift while dragging for fine control. Or click the year label to type one in directly.
4. Submit. You score on both place and time. Five rounds per session.

No login is needed. Your progress lives in your browser. To enter the public leaderboard you'll be asked for an email at the end of a run — that's the only time it asks.

The five modes

Classic

Five random panoramas from the full archive of 100 historical scenes. Play as many runs as you want.

Daily

The same five rounds for every player worldwide, seeded by today's UTC date. One attempt per day. Builds your daily streak, which earns freezes (skip a day without breaking it) every seven days.

Duel

After finishing any session, click Challenge a friend to generate a 6-character code. Send the link. Whoever uses it plays the same five rounds you just played and tries to beat your score.

Eyewitness

No panorama. You read a three-line first-person account from someone who was there ("we rise before the river god is bright and haul ropes…") and deduce where and when. The panorama is revealed only after you submit.

Newspaper

No panorama. You read a redacted newspaper clip with names and places blacked out. Decode the era and place from context clues. Same reveal payoff at the end.

How scoring works

Each round is worth up to 5,000 points. You earn a place score and a time score, then they're combined.

• Place score decays smoothly with distance. Within ~8 km is perfect. Pinning the right country gives +800 bonus; right continent gives +300.
• Time score decays based on the era. Ancient rounds are forgiving (within ±380 years scores well); modern rounds are tight (within ±22 years).
• The two combine non-linearly: place counts a bit more than time. The result curve for each round is shown at reveal.

Your final round score is then multiplied by your wager (1×–3×) and reduced by any hint costs you spent.

Hints & the confidence wager

Hints let you spend round score in exchange for information:

• Continent (−300) — names the continent.
• Century (−300) — names the century.
• Compass (−150) — gives a rough bearing from prime origin to the answer.

Confidence wager (1×, 2×, 3×) multiplies your final round score. High wager + correct = leaderboard glory. High wager + wrong = bigger penalty. Set it before submitting.

You can also use the timeline:

• Drag normally for fast scrubbing.
• Hold Shift while dragging for ~5× finer control.
• Click the year label to type in a year (e.g. 1492, 1492 CE, 500 BCE, -500).
• Arrow keys nudge ±5 years (Shift+arrows for ±1).

Sharing and friend duels

At the end of a run you'll see four share buttons:

• Copy result — Wordle-style emoji grid for chat. No spoilers.
• Save card — a polished PNG of your run with the world map and pins.
• Save replay — a 12-second WebM clip animating your run round by round.
• Challenge a friend — generates a duel link your friend can play.
• Spectator link — a read-only URL anyone can use to see your finished run.

When you paste a daily or duel URL into Discord, Slack, or Twitter, it auto-renders a custom unfurl image with today's stats or the duel code.
