Placing Your Guess

Click anywhere on the world map to drop a pin. You can zoom, pan, and search for locations. The closer your pin is to the actual event location, the higher your score. You can move the pin as many times as you want before submitting.

Choosing the Year

Use the year slider or type directly to pick when you think the event occurred. The year range is customizable per game (default is from 400 BC to the current year). The smaller the gap between your guess and the actual year, the more points you earn.

Using Hints

Each round offers hints organized in five tiers. Hint types include Century, Historical Event, Decade, Contemporary Event, Visual Clues, Continent, Remote Landmark, Region, and Nearby Landmark. Hints are independently purchasable—no prerequisites required. Each hint costs accuracy and XP penalty. Use them wisely.

Frequently Asked Questions

Each round gives you up to 200 XP: 100 for location accuracy and 100 for year accuracy. Location score decays with distance from the actual place (max 20,000 km). Year score decays with the difference from the actual year (max 200 years). Hint penalties are subtracted after the round.

Game is not loading or stuck on black screen
Try refreshing the page. If the issue persists, clear your browser cache and cookies, then reload. Ensure you are using a modern browser (Chrome, Firefox, Safari, Edge).
My friend did not receive the invite
Make sure your friend is logged in. Invites appear in the notification bell at the top right. As a fallback, copy the 6-character room code and share it directly via any messaging app.
Timer ran out before I could submit
In Live mode, guesses are auto-submitted when time expires. If you need more time, ask the host to disable the timer or switch to Anytime mode which has no time limit.
Hints are not showing any information
Hints must be purchased before they reveal content. Click the hint button, confirm the purchase, and the information will appear. Each hint reduces your final score.
Score seems lower than expected
Check if you used hints—they apply penalties to both accuracy and XP. Also verify your distance from the actual location and year difference. The max per round is 200 XP (100 location + 100 year).
