The complete rules of Mas o Menos

Mas o Menos ("More or Less") is a party trivia game about percentages. The in-game tutorial covers the basics in four screens; this page is the full reference — every scoring rule, setup option, and edge case.

The core idea

Every question in Mas o Menos has an answer that is a percentage between 0 and 100: "What percentage of Olympic gold medals in a given sport went to one country?", "What share of adults say they have read a book in the past year?", and so on. You are almost never expected to know the exact figure. Instead, the game splits each round into two jobs: one player commits to a specific guess, and everyone else judges whether the truth is higher or lower than that guess. Being roughly calibrated beats being encyclopedic.

A round, step by step

1. The guesser locks in a number

Play rotates through the players. On your turn you read the question aloud (or read it from the shared screen in online play) and enter a percentage from 0 to 100. You cannot change it once it is submitted. There is no penalty for a wrong guess, so a confident, specific number is always better than a vague one near 50.

2. Everyone else votes More or Less

Every other player privately chooses whether the real answer is Más (more than the guess) or Menos (less than the guess). Votes are cast at the same time and are hidden until the reveal, so there is no benefit to waiting to see what other people pick.

3. The reveal

The real percentage appears along with a short fun fact that gives the number context. The app then scores the round automatically.

Scoring

• The guesser earns up to 3 points based on how close the guess landed to the real answer. An exact hit is the full 3; the points taper off as the gap widens; a wild miss earns nothing.
• Every other player earns 1 point for a correct More or Less vote, and nothing for an incorrect one.
• If the guess is exactly equal to the answer, votes are treated generously so voters are not punished for an impossible call.

Because the guesser can score more per round but only on their own turn, and voters score smaller amounts every round, the game tends to stay close. A player who is not great at picking exact numbers can still win on consistent voting.

Setting up a game

• Players: 1 to 10. Solo play is a personal challenge against the point scale. Three to six players is the best party range.
• Rounds: choose a fixed number, or unlimited rounds if you would rather stop whenever you like. With a fixed count, the game ends automatically and shows the final standings.
• Answer timer: set a per-turn time limit, or turn the timer off entirely for a relaxed game. When the timer is on and it runs out before a guess is submitted, the turn is skipped and no points are awarded for it.

Offline (pass-and-play) vs online

Pass-and-play uses a single device that moves around the room. The guesser holds the phone for their turn, then hands it off so each other player can tap in their vote without the guesser seeing. No internet connection is needed once the app has loaded, which makes this mode reliable on a road trip or anywhere signal is poor.

Online multiplayer gives each player their own screen. One person creates a free account and hosts a room; the app produces a short room code; everyone else enters that code on the Join screen to connect. All players see the same question and answer their part of the round simultaneously, and the host's device keeps the authoritative score. If someone's connection drops mid-game they can rejoin the same room with the code and pick up where the room is.

Common questions about the rules

Can I look up the answer?

Nothing stops you, but it defeats the point — and in a timed game you usually will not have time. The fun fact on the reveal screen is there to reward you with the context after the round, not before.

What happens on a tie at the end?

The final standings show tied players at the same rank. Add one sudden-death round as a house rule if you want a single winner.

Do stats carry between games?

Yes. Win rate, average guess error, and best score are tracked on your device, and also on your account if you play online.
