Custom BluGame — for venues and events →

Party games · Bluetooth · No server

Sit down together.
Start playing in 30 seconds.

BluGame is a family of phone party games — 21, Wilki, Mafia, Love Letter, Impostor — playable only when you're actually together. Phones connect directly over Bluetooth, with no internet and no server standing in the middle of the game.

The browser shows the app from the inside, not real gameplay — Bluetooth between phones needs a native app (and on iPhone, no browser can speak BLE at all).

How it works

Zero accounts. Zero waiting. Zero internet.

1

Open the app, everyone on their own phone

No sign-up and no login — you don't create an account or invent any passwords. Your identity for playing is created automatically in the background, on your phone only.

2

Whoever starts the table, the rest join in

There's no "host" in the sense of authority — just the phone that happened to announce the game over Bluetooth first. It disconnects exactly like any other player.

3

You play — in the park, on the bus, on the balcony

No server sits in the middle of the game, so signal coverage doesn't matter. All that matters is being physically close to each other.

Why BluGame exists

Five rules we don't touch

These aren't slogans — they're the rules we design every screen and every line of code against, since day one.

Rule 1

Fairness as a foundation, not a slogan

Cards are shuffled by cryptography (a "mental poker" style protocol), not by trusting the app — designed for fully fair play, so that no device ever knows anyone else's hand.

Rule 2

Egalitarian — no host in charge

The phone that starts the table has no special position at all. It disconnects exactly like any other player, and the game doesn't even notice.

Rule 3

The phone as a tool FOR being together

Zero pushy notifications, zero addictive mechanics, zero dark patterns designed to glue you to the screen instead of to each other.

Rule 4

No moderator, no barriers

We measure the time from opening the app to the first card on the table in seconds. Every extra onboarding step has to earn its place.

Rule 5

A warm, familiar tone

The app should sound like a good friend, not a corporation — in the interface, in the copy, and in the terms of service.

By the numbers

0 servers, 0 accounts, 1 evening

Every game and mode is free forever — a paywall on a single game would split up a group of friends who wouldn't all pay the same.

Portfolio

Many games, one piece of infrastructure

Every new game reuses the same Bluetooth foundation — you add it to the evening, you don't start from scratch.

21

2–4 players · Not available on iOS

A Polish twist on blackjack, dealt from a cryptographically shuffled deck. Draw cards trying to get closer to 21 than the rest of the table — no dealer, no real money, purely for points. Rules and features →

Wilki

4+ players

A classic hidden-role game — some players are werewolves hunting by night, the rest try to track them down by day. The app plays narrator, so nobody sits out after being eliminated. Rules and features →

Mafia

4+ players

A hidden-role game in a mafia setting. Night actions, morning votes, and less certainty by the round about who you can trust — and the mafia has its own hierarchy: the Godfather decides the night's victim, and the Consigliere takes over when he is gone. Rules and features →

Love Letter

2–4 players

A light deduction card game — you hold one card and have to get rid of it before you work out what everyone else is holding. A round takes just a few minutes. Rules and features →

Impostor

4+ players

Everyone except one person knows the same secret word. In a round of word association, you try to spot the Impostor, who's improvising with no idea what's going on. Rules and features →

Kalambury emoji

2–4 players

The table's host knows the word or phrase and describes it using emoji only — adding them one by one while everyone else sees them appear live on their phones and types in guesses. The first to get it right scores a point; a round lasts at most two minutes. The describer's role never rotates — the same player, the host, describes throughout the game. Rules and features →

Quiz

Host + players

The host reads the questions and answer options aloud, and each player picks one answer in the app — they can still change it until the round ends. The app only times the round and collects answers; the host sees live who picked what and can pause the clock. Rules and features →

Questions everyone asks

Before you ask

Is 21 gambling?

No — there's no real money or exchange of value involved. It's a digital version of a classic card game meant for playing among friends, just like at a real table.

How do I know nobody's cheating?

Shuffling and hiding cards is designed for fully fair play: no single device — including the phone that started the table — ever has access to anyone else's cards. The mechanism is built on publicly known cryptographic techniques (so-called "mental poker").

Do I need internet?

Not during play — with one exception: the Quiz in its Custom version (for venues) needs a constant internet connection for the presenter and at every team table. Phones connect directly over Bluetooth Low Energy — in all the other games you may only need internet the first time you download the app.

How many people can play at once?

Depends on the game: 21, Love Letter and Kalambury emoji are 2–4 players, Wilki/Mafia and Impostor are 4 and up, and the Quiz takes any number of players — the more, the longer and more interesting the evening.

What happens to my data?

The app has no account and no login — your identity is a key pair created automatically and stored only on your phone, with no steps on your part. Details in the privacy policy.

Does the BluGame app have ads?

No. The BluGame app contains no ads, ad networks or sponsored content, and we don't sell ad space. At a venue using Custom BluGame, the venue can show players its own logo, welcome text and house rules — that is information from the venue, not advertising.

What languages is the app available in?

The app is available in 5 languages: Polish, English, Spanish, French, and German. Each phone detects its own language from its device settings, so at the same table every player can play in their own — everyone still joins the same game. One exception: the secret words in Impostor are currently Polish-only; translating that word bank is planned as a next step.

Get the crew together. The rest takes 30 seconds.

The app is free, with no ads and no account to create.
