Every vault shows four picture-magnets. Together they hint at a single moment in history.
Stuck? Spend points or watch an ad to reveal a clue β the century, the decade, the last digit.
Enter the year and crack the vault. Solve for points; the safe locks down if you rush it.
What's inside
Kings & Rulers, Science, War & Peace, Art & Letters, Faith, Exploration, and more.
Every era is fair game β ancient Olympiads to the space age. Magnitude only; no era to pick.
