Timeline Detective Game
Play a free sequencing game right in your browser. Everyday Events puts the steps of a familiar routine — making a sandwich, planting a seed, getting ready for bed — back in order. Invention Timeline puts a handful of major, well-known inventions back in the order they were invented, from the wheel to smartphones. Mixed Review combines both. Tap the cards in order, check your answer, and see the correct sequence if you miss one. No sign-up, and nothing is saved.

Examples to try
Everyday Events: Making a Sandwich

Tips for better results
Start with Everyday Events
Familiar routines are the most intuitive way to learn the tap-to-order mechanic before trying Invention Timeline.
Tap a placed card to undo it
If you change your mind, tap a card already in your order to send it back — no need to start the round over.
Use the correct-order reveal to learn, not just score
A missed round always shows the full correct order, so it's a teaching moment even when the answer isn't perfect.
Session best isn't saved
The score shown is just for this browser session — nothing is stored, so every visit starts fresh.
How the timeline detective game works
Everyday Events draws from a bank of 16 original, safe, familiar routines — no current events, and nothing that requires a value judgment — each shuffled into a fresh, scrambled order for you to solve.
Invention Timeline draws a random handful of items from one master, well-established chronological list of 12 major inventions. Only the relative order is ever used — no specific years are shown — and every pair on the list is separated by decades or centuries, so the correct order is never a close or disputable call.
Everything runs in your browser — nothing you tap is uploaded, and no score or progress is saved after you leave the page.

Frequently asked questions
Is Timeline Detective free?
Yes, completely free, with no account and no limit on how many cases you play. There are no ads.
What's the difference between the three categories?
Everyday Events puts the steps of a familiar routine back in order. Invention Timeline puts a handful of major inventions back in chronological order. Mixed Review combines both.
Does the game show specific invention years?
No. Only the relative order (which came first) is ever shown or asked about — no exact dates or years appear anywhere in the game.
Is the invention order accurate?
Yes. Every invention on the list is separated from its neighbors by decades or centuries, so the order used is well-established and not a close or debatable call.
Is this game about current events or politics?
No. Every sequence is either a safe, everyday routine (like making a sandwich) or a long-settled historical invention timeline — nothing current-events or political.
How do I undo a card I tapped by mistake?
Tap the card in your order (not the bank below) and it moves back to the bank so you can place it again.
Does this use AI?
No. This is a browser-only game with a fixed, hand-written set of sequences. It does not use AI, and the game runs entirely on your device.
Are scores saved?
No. Your score, streak, and session best stay in your browser for the current session and are cleared when you leave the page.
