Duped — The Daily Bluff Game

Duped is a free daily bluff game where one true, barely believable fact hides inside a lineup of lies — some written by yesterday's players, some by an AI trained to sound convincing. Every day there is exactly one new case. You read the question, study the answers, and pick the one that isn't lying to you. Guess right and your truth streak grows. Guess wrong and you've been duped — and somewhere out there, the player who planted that lie takes the credit. Then the badge comes off: you write a lie of your own for tomorrow's case, and come back the next morning to find out how many people fell for it.

THE GAME

What is Duped?

Duped is a bluffing trivia game — think of it as two truths and a lie turned inside out. Instead of two truths and one lie, every case gives you one verified truth buried in a pile of fabrications. The question is always real and always a little hard to believe: the kind of fact that makes you say “that can't be right” just before you discover that it is.

What makes the game tick is where the wrong answers come from. They aren't written by a quizmaster trying to be fair. They're written by other players trying to fool you, sharpened by an AI that fills in the gaps, and filtered by a review pass that throws out anything too close to the truth. The result is a lineup where every option sounds plausible, exactly one is real, and the rest were engineered to end your streak.

You don't need an account to play. Open the site and today's case is waiting — the game runs in your browser, remembers your streaks on your device, and never asks for an email address. One case goes live every day and closes at midnight UTC, when the next one takes its place. Closed cases move to the archive with the answer revealed, along with the lies that fooled the most players.

THE LOOP

How to Play

1. Play the detective

Today's case opens with a single question and a handful of answers. One of them is the verified truth; the others were planted to deceive you. Read carefully, distrust anything that sounds too neat or too dramatic, and lock in your pick. You get one guess per day — no second chances, which is exactly what makes the choice interesting. The moment you answer, the reveal shows whether you found the truth or got duped, which lie fooled you, and what percentage of players got it right.

2. Become the liar

After you answer, the roles flip. You get a preview of tomorrow's question and one shot at writing a lie for it — a fake answer that will be shuffled in with the truth and shown to every player who comes after you. Good lies are specific, boring in the right ways, and just plausible enough to feel safe. Lies that land too close to the real answer get rejected in review, so bluffing well takes actual craft.

3. Return for the verdict

The next day your verdict comes in: how many players saw your lie, how many picked it, and whether you ended anyone's truth streak. Fooling a third of the field feels great; watching your lie outperform the AI's feels even better. Then today's case is waiting, and the loop starts again. The full rules live on the how-to-play page.

THE STAKES

Two Streaks to Guard

Duped tracks two streaks, and they pull against each other in a way most daily trivia games don't. Your daily streak counts consecutive days you've shown up and played, win or lose. It rewards the habit — the same pull that keeps people coming back to a daily crossword.

Your truth streak counts consecutive days you've spotted the real answer. This is the one worth bragging about, and the one everyone else is actively trying to break: every lie in today's lineup was written by someone hoping to end it. One convincing fake is all it takes, and the game will tell you exactly whose lie got you.

Every result turns into a compact, spoiler-free share card — your case number, your verdict, and your streaks — built for the group chats where friends compare results without ruining the answer. There's no global leaderboard to grind; the scoreboard is the group chat.

THE LIARS

Where the Lies Come From

Most trivia games live or die on their question writers. Duped lives on its liars. Every wrong answer in a case has one of two origins: a player who solved yesterday's case and chose to plant a lie, or an AI asked to generate decoys in the same register as the truth. Player lies tend to be the dangerous ones — humans are unreasonably good at inventing the small, mundane details that make a fabrication feel real.

Before any lie reaches the lineup, it passes a review step. Anything factually true, too close to the real answer, or trying to smuggle in a spoiler gets cut. What survives is a set of answers that are wrong, safe, and genuinely hard to tell from the truth — which is the whole game.

THE RHYTHM

Why One Case a Day

Duped follows the rhythm that Wordle made famous: one puzzle per day, the same puzzle for everyone, gone at midnight. If you like daily games like Wordle, the shape will feel familiar — a two-minute ritual with your coffee rather than an endless feed.

The daily limit isn't just pacing. Because everyone faces the same case, your result means something when you share it, and the lies get a full day to rack up victims before the verdicts land. Scarcity is also what makes the streaks matter: you can't grind your way back after a bad day. You can only come back tomorrow.

THE FINE PRINT

Frequently Asked Questions

Is Duped free to play?

Yes. Duped is completely free and playable in any modern browser at getduped.app. There is nothing to install and no paywall — the site is supported by a small, unobtrusive ad.

Do I need an account?

No. The game stores an anonymous id in your browser to remember your streaks and whether you have played today. No sign-up, no email, no password. Clearing your browser storage resets your streaks, so treat them kindly.

When does a new case start?

A new case goes live every day at midnight UTC, everywhere at once. The current case closes at the same moment, so late-night players in California and early risers in Berlin are always looking at the same board.

What happens if I get duped?

You will see the truth, the lie that fooled you, and how many other players fell for the same one. Your truth streak resets, but your daily streak survives — showing up counts. Then you get your revenge: write a lie for tomorrow’s case.

How are lies moderated?

Every submitted lie goes through review before it can appear in a case. Lies that are accidentally true, too close to the real answer, or inappropriate are rejected. The goal is a lineup that is hard because it is clever, not because it is unfair.

Can I read past cases?

Yes. The archive lists every closed case with its question, the verified truth, and the lies that fooled the most players. Past cases are not replayable for score — the daily case is the game — but the archive is an excellent training ground.

Is there a mobile app?

Not yet. The site is built mobile-first and works like an app in your phone’s browser — add it to your home screen and it is one tap away. If a native app ever happens, the streaks you have built will be the reason.
