Every day, Chrono Trivia gives you a set of real events - moments from history, entertainment, science, sports, technology, or pop culture. Your job is simple: arrange them in chronological order, from the earliest event at the top to the most recent at the bottom.
Category puzzles give you 4 events and 3 attempts. The Daily Mix is the main challenge - 6 events and 4 attempts. After each attempt, you'll see how many events are out of place so you can adjust your answer.
Your score is based on how quickly and efficiently you solve the puzzle. Here's how points are awarded:
| Result | |
|---|---|
| Solved on 1st attempt | 100 pts |
| Solved on 2nd attempt | 80 pts |
| Solved on 3rd attempt | 60 pts |
| Solved on 4th attempt (Daily Mix only) | 40 pts |
| Speed bonus (under 30 seconds) | +10 pts |
| Hint used | −15 pts |
| Did not solve | 0 pts |
💡 The maximum score is 110 points - solve on your first try in under 30 seconds with no hints! Category puzzles give you 3 attempts, while the Daily Mix gives you 4.
Classic Mode: Arrange the four events in the correct order. This is the default mode and is great for all skill levels. You only need to get the sequence right - no need to guess specific years.
Expert Mode: In addition to arranging the events, you must also guess the year each event occurred. Your year guess is counted as correct if it's within 2 years of the actual date. Expert mode is perfect for history buffs who want an extra challenge.
Chrono Trivia features 7 puzzle categories, each with a unique daily puzzle:
🌀 Daily Mix - The main event! Features 6 events from all categories combined (instead of 4), with 4 attempts to solve. This is the puzzle everyone plays, perfect for competing with friends since everyone gets the same events.
🎬 Entertainment - Movies, TV shows, music, and media milestones.
💡 Technology - Inventions, gadgets, apps, and digital breakthroughs.
🏅 Sports - Championships, records, and legendary athletic moments.
🔬 Science - Discoveries, space exploration, and medical breakthroughs.
📜 History - Major world events, political milestones, and cultural shifts.
🎨 Pop Culture - Viral trends, toys, internet culture, and social media moments.
After your first attempt, you can unlock a hint that reveals which decade one of the misplaced events belongs to. Using a hint costs 15 points from your final score, so use it strategically - sometimes it's better to reason it out on your own!
Win at least one puzzle each day to build your daily streak. Your streak counter shows how many consecutive days you've played and won. Missing a day resets your streak to zero, so come back every day to keep it alive!

After completing a puzzle, tap "Share Result" to copy or send your score to friends. The share text shows your score, time, and streak without spoiling the answers. You can also share your entire daily summary after completing multiple categories - perfect for group chats and friendly competition!
💡 Don't overthink it - start with any events you're confident about, then fill in the gaps.
💡 Look at the descriptions for clues. Words like "first," "launches," or "debuts" often signal earlier events.
💡 The Daily Mix is the best category for competing with friends since everyone gets the same puzzle.
💡 Try Expert mode once you're comfortable - guessing years is harder but more rewarding!
Chrono Trivia features a database of hundreds of curated events across all categories. New puzzles are generated daily, and every event is used only once before the cycle repeats - so you'll keep discovering new facts for months. All players around the world get the same puzzles on the same day, making it fair for competition.
