Today's 10 use the UTC date, so friends on that calendar day get the same cards.
Each card is one milestone, told in a sentence or two. The drawing is type, color, and a generic mark. There are no product logos and no borrowed photos. The year is the thing you supply. Lock it in and the card names the documented year, how many years you missed by, and one fact about that date.
An exact year is 100 points. The score falls as the gap grows: a miss of about a dozen years is still worth a few dozen points, and a miss large enough to round under one point scores zero. Ten cards make a round, so a perfect round is 1000. The rank is that total. The decade line looks at the real years, averages your points inside each decade, and names the decade you know best. A tie goes to the decade with more cards, then to the earlier one.
Daily mode does not call a server. This page hashes the UTC date and deals 10 cards from that number, so two people on the same UTC calendar day get the same order. A random round is a fresh shuffle. Play again on a daily date keeps the higher score for that date. The best score is the best round on this device, daily or random.
The set runs from the telephone and the bulb through networks, games, discs, and the recent chat tools. Where a lab date and a public date disagree, the fact says which one the year marks. The first-website card is one of those: the reveal separates the day the page was already running from the day the wider internet was told.
Guesses disappear when you leave or deal again. This browser can keep the best total and the daily total, and Clear saved scores deletes both. If a later save fails, the status says this browser is not keeping the latest score.
Tech Myth or Fact is the swipe quiz for the claims people repeat. Which Tech Era Are You? maps habits to seven eras. Prompt Battle is the head-to-head on writing a better prompt, and the Password Habit Quiz scores reuse and a second factor without asking for a password.
No. The game runs in your browser. The only things saved are your best score and the daily score for the UTC date you played, in this browser's local storage. Individual guesses are not stored and are not sent anywhere.
An exact year is 100 points. The score then falls with distance: each year off multiplies the remaining score by a curve that is about 37 points at 12 years away, and anything that would round below 1 point becomes 0. A round is 10 cards, so the top score is 1000.
Today's 10 is a fixed set of cards chosen from the UTC calendar date, computed in this browser. A friend who opens the game on that same UTC date gets the same cards in the same order. There is no server and no account. Play again on the same date keeps the higher daily score.
Yes. Each card uses a widely documented calendar year, and the reveal adds a one-line fact. Where a day is settled, the fact names it. Where historians split a public unveiling from lab work, the card says which event the year marks. It is a quiz, not a citation list.
Drag the slider or type a four-digit year. Arrow keys move one year, and Shift plus an arrow, or Page Up and Page Down, moves ten. Enter locks the year. The same steps are buttons, so a screen reader can play without dragging. After the reveal, Next card moves on, and Enter does too when focus is not already on a button.
Only in this browser. Clear saved scores deletes both. Clearing site data for cyberscryb.com removes them too. The game does not ask for an account, and leaving the page drops the current round.
