History Timeline Sort

How to play

1. Read all six events, then use the ▲ ▼ buttons to move each one — earliest at the top, latest at the bottom.
2. Press Check order. Events in the right spot turn green and lock in place; the rest stay movable.
3. Rearrange the remaining events around the locked ones and check again — you have 3 checks in total.
4. Whatever happens, the full timeline is revealed at the end with each event's year and a one-line story worth remembering.

Rules

• One board of six events per day, keyed to midnight UTC — identical for every player worldwide.
• Order runs earliest → latest from top to bottom; BC years count as earlier than all AD years.
• After each check, correctly placed events lock and can no longer be moved — locks never come undone.
• Every daily board keeps at least a 2-year gap between any two events, so there are no ambiguous ties.
• Events rotate through a large bank; the same event will not reappear for weeks.

Scoring & streaks

Your result is how many checks you needed (1–3), plus an emoji strip per check showing which positions were right. A first-check perfect sort is the flex. Solving the genuine daily board — not an archive replay — extends your on-device streak.

Strategy tips

• Anchor the extremes first: the clearly oldest and clearly newest events are usually safe bets, and locking them shrinks the middle.
• Date what you can, then interpolate. Even a rough guess like "1800s-ish" is enough to seed a position between two anchors.
• Use your first check as a probe: with six slots, even a half-informed arrangement usually locks two or three positions and tells you where the confusion lives.
• Watch for era clusters — two industrial-age inventions or two space-age missions close together are almost always the intended trap.
• Tie events to lifetimes and technology: if one event needed electricity, radio or flight to exist, it can't precede the invention it relies on.

Difficulty

Rounds take 2–5 minutes. Boards mix easy spreads (a pyramid vs. a smartphone) with genuinely tricky adjacencies a few decades apart. The bank leans on well-documented, widely taught moments — the challenge is ordering, not obscurity.

Controls

• Move events with the ▲ ▼ buttons; moves hop over locked rows automatically.
• Keyboard: Tab between buttons, Enter or Space to activate — every control is a real button.
• The archive picker above the board holds the last two weeks of timelines on this same page.

Accessibility

The entire game is playable by keyboard, every move button carries a descriptive label ("Move X earlier"), lock-state is conveyed in text and structure rather than color alone, announcements go through a polite live region, and the list layout keeps readable contrast in both themes on small screens.
