## In short

- A good debate game forces everyone to pick a side in under five seconds, limits speaking time and delivers a verdict. Without those three rules it isn't a game, it's a conversation that drags.
- Here are 9 debate games tested: three apps (Unpopular Opinions, Debatium, OpinionGame), a free classroom platform (Kialo Edu), two card games (The Voting Game, Wavelength) and three formats that need nothing at all.
- Our pick for a party: opinions you vote on. One statement, everyone votes at once, the minority justifies itself, and the real percentage of other players settles it. That's what Unpopular Opinions does, with more than 2 million votes.


## What makes a good debate game

A debate between friends dies in three ways: nobody dares to pick a side, someone hogs the floor, and you never know who won. A debate game exists to fix those three flaws.

- **Sides are forced.** You draw your side at random, or you vote agree / disagree with no "it depends". Defending a side you didn't choose is funnier than defending your own.
- **Time is limited.** One minute per debater, or thirty seconds for the minority. When the timer goes, you move on.
- **There is a verdict.** A judge, a table vote, or a percentage. Without a verdict the debate ends with "well, to each their own", which is the worst possible ending.

The nine games below follow those rules, each in its own way. They are sorted by format: apps first, then physical games, then what you can play with nothing.

## 1. Unpopular Opinions: the debate with a numbered verdict

**How it works.** An opinion shows up: "Soft sandwich bread is better than a baguette." Each player swipes right if they agree, left if they don't. The app reveals whether the take is Popular or Unpopular, with the real percentage of all players: 12% on that one, on more than 5,000 votes. The minority justifies itself, next opinion.

**What works.** It's the fastest debate format there is: no topic to understand, no side to draw, just a statement and a reflex. Every card produces a mini-debate of thirty seconds to five minutes. The percentage acts as a third player: when the whole table agrees but 75% of players think the opposite, the table has to explain itself. More than 2,000 opinions, eight themes (Classic, Couples, Food, Sports, Politics, Controversial, Sexual, Random), one phone passed around, no rules to explain.

**What works less.** It isn't an argued debate with a judge: you vote, you justify, you move on. If your group wants five-minute jousts with a declared winner, the one-minute debate does better. And the app is iPhone-only for now.

**Best for.** Pregames, nights with friends, couples, groups that barely know each other. Fifty opinions to try without the app: [50 unpopular opinions](/en/blog/unpopular-opinions-examples/). [Download on the App Store](https://apps.apple.com/us/app/unpopular-opinions/id6739219396).

## 2. Debatium: debate questions with penalties

**How it works.** Made by Les Ignobles, Debatium runs through debate questions in six packs (Classic, Caliente, Trash, End of the night, Couples, Random). After each question, penalties hit the laziest, the chattiest, or whoever never commits.

**What works.** The questions are written for two or three people who actually talk, and the penalty system punishes exactly the behaviors that kill a debate. Available on iOS and Android, no ads.

**What works less.** No numbered verdict: the table decides alone. The most interesting packs are Premium.

**Best for.** A couple or a small group that wants deep debates more than reflexes.

## 3. OpinionGame: debates, would-you-rather and truth-or-dare mixed

**How it works.** Up to ten players, a category, and cards that carry the name of whoever has to read and answer, with possible penalties. The app mixes three formats: debate between friends, would you rather, and truth or dare.

**What works.** Mixing formats avoids fatigue, and the name on the card makes it clear who speaks. Free with plenty of questions available without a subscription, no ads.

**What works less.** It isn't a pure debate game: between two debates there are dares. And with no statistics, you never know whether your take is actually in the minority.

**Best for.** Groups of five to ten that want one app for the whole night.

## 4. Kialo Edu: structured debate for the classroom

**How it works.** A free online platform where a class builds a debate as a tree of arguments for and against a thesis. Students add claims, rate them, and see the whole argument map.

**What works.** It's the reference for teaching what a balanced, sourced debate looks like, and it's free for teachers. Students defend positions that aren't their own and see the structure of the argument.

**What works less.** It isn't a party game: you need a session, a moderator and some preparation.

**Best for.** Teachers, debate clubs, youth groups.

## 5. The Voting Game: who is most likely to…

**How it works.** A card game where everyone anonymously votes for which player in the group best fits the question on the card. Votes are tallied and revealed, and players find out who voted for whom.

**What works.** Anonymous voting makes people honest, and the reveal creates instant debates: "who voted for me?". It's the physical cousin of the opinions vote, aimed at people instead of statements.

**What works less.** It needs a group that knows each other, and it's about the players, not about ideas: with strangers it falls flat. A box to buy.

**Best for.** Groups of five to ten close friends.

## 6. Wavelength: guess where the other person stands

**How it works.** A board game (with an app version): a player sees a position on a scale between two extremes ("cold" / "hot") and gives a clue; their team has to guess where the dial sits.

**What works.** It's clever, it creates discussions about how each person perceives things, and it works with a single phone or the box.

**What works less.** It takes two teams and some concentration, and it's about perception more than opinion. Not for a loud pregame.

**Best for.** Groups that like board games.

## 7. The one-minute debate (no materials)

A topic is thrown out, two volunteers flip a coin for their side. One minute each, timer on a phone. Then the table votes by show of hands. The loser picks the next topic.

**Why it works.** Drawing the side at random is the rule that changes everything: defending "brunch is overrated" when you love brunch produces much better arguments. Prepare twenty topics in advance, or pull from [the 50 unpopular opinions](/en/blog/unpopular-opinions-examples/).

## 8. For or against (no materials)

The host reads a topic: "For or against pineapple on pizza." Everyone raises a hand for or against at the same time. One "for" and one "against" each get one sentence to convince, then you vote again. Whoever changed their mind names the winner.

**Why it works.** The second vote measures persuasion, not the starting opinion. It works with thirty people as well as three, which is why it shows up in team buildings and camps.

## 9. Opinions you vote on (no materials, or with the app)

Someone reads a statement out loud. On a signal, everyone votes at the same time, thumbs up or thumbs down. The minority gets thirty seconds to justify itself. Next statement.

**Why it works.** It's format #1 without the phone: the fastest to start, the easiest to understand, the only one that still works at two in the morning. With [Unpopular Opinions](/en/), the real percentage of other players adds the verdict you miss when playing from memory.

## Our pick by situation

- **Pregame with friends, you want people talking fast:** opinions you vote on, with or without the app.
- **Two or three people, you want deep debates:** Debatium.
- **Five close friends who like to argue for fun:** The Voting Game.
- **Ten people who want one app all night:** OpinionGame.

## Frequently asked questions

### What is the best debate game for friends?

For a party, a game of opinions you vote on: Unpopular Opinions (one statement, everyone swipes agree or disagree, verdict as a percentage). For argued debates with a judge: The Voting Game for vote-based rounds, or the one-minute debate with no materials. For teens or a classroom: Kialo Edu, free and built for it.

### Which app can I use for debates with friends?

Unpopular Opinions (iPhone, free, divisive opinions with the other players' percentage), Debatium (iOS and Android, debate questions with penalties) and OpinionGame (iPhone, debates, would-you-rather and truth-or-dare mixed). One phone is enough in all three cases.

### How do you run a debate game with no materials?

Three formats work with nothing: the one-minute debate (one topic, two sides drawn at random, one minute each, the table votes), for-or-against by show of hands, and opinions you vote on (one statement, everyone votes at once, the minority explains). You just need someone to read the topics and a timer.

### Can a debate game be played online or long distance?

Yes. On a video call, read the opinion, everyone answers at the same time on a signal, the minority justifies itself. With the Unpopular Opinions app, each player swipes on their own phone and you compare your verdicts and the other players' percentage.
