BluGame

How it works

Zero accounts. Zero waiting. Zero internet.

Open the app, everyone on their own phone

No sign-up and no login — the app creates you an identity protected only by your own recovery phrase. Nobody knows it but you.

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.

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 marketing copy — 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, 5 games, 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

Five 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

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.

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.

Mafia

4+ players

The same hidden-role mechanics as Wilki, in a mafia setting instead of werewolves. Night actions, morning votes, and less certainty by the round about who you can trust.

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.

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.

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. Phones connect directly over Bluetooth Low Energy — you may only need internet the first time you download the app.

How many people can play at once?

Depends on the game: 21 and Love Letter are 2–4 players, Wilki/Mafia and Impostor are 4 and up — 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 protected only by a recovery phrase that only you know. Details in the privacy policy.

What if I didn't save my recovery phrase?

If you didn't save it and still have the app installed — nothing happens, you don't need the phrase to play. If you uninstall the app without a saved phrase, you lose access to that identity permanently — reinstalling just creates a new one for you, with zero history, no need to provide anything.

Does the BluGame app have ads?

The app is labeled "Contains ads" on Google Play, and that's true — but only in one specific case. If you connect to a Custom BluGame table at a venue or event that broadcasts its own personalized version of the BluGame games over Bluetooth, you'll see that venue's branding/message — that's the "ad". If you never do that, the BluGame app has no ads at all, and we intend to keep it that way.

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.
