Put a phone in the middle of the table.
Everything else is already on it. No props to fetch, no account to make, nothing to download if you do not want to.
What is actually on the cards
These are real.
Every prompt in PartyStack was written for PartyStack. Here are three of them, straight off the deck.
Never Have I Ever
Never have I ever pretended to know a song I had never heard.
Confessions
The pettiest thing you have ever done
Hot Takes
Cereal is a soup.
How a night runs
A night, not a menu.
Most party apps are a grid and nothing else. The grid is where a group puts the phone down and starts talking about something else.
Pick something
Grouped by what playing feels like — sit and read a card, get up and act, everybody on their feet. Every row says what the game is, because a title tells you nothing about a game you have never heard of.
Play it
The phone deals, times and keeps score. It is not a judge — it cannot hear the room, and every rules card says so, because a group that thinks the phone is refereeing argues with the phone instead of each other.
It hands you the next one
No game-over screen dead-ends into the library. Each one names a specific next game, playable right now with the people who are actually here, and deliberately a different kind from the one that just ended.
The library
59 games. All original.
Not a list of names you already know with the serial numbers filed off. Every deck, every word list and every drawing was made here.
Nine cultures, not one
Word chains were invented five times.
Antakshari in India, Shiritori in Japan, 끝말잇기 in Korea, 接龍 in China, Word Chain in English. Same mechanic, five cultures, one rule different each. Most apps ship the English one. We ship all five, under their own names.
Secrets, on one phone or several
Nobody sees anybody else's screen.
Hidden roles and secret words only work if the secret stays secret. On one phone, the screen hands over deliberately and tells you to check nobody is looking. With several phones in the room, they find each other over Bluetooth or shared wifi and deal each person their own private view.
Either way: no internet, no server, no account.
Questions people ask
Does PartyStack need an internet connection?
No. Every game, prompt and word list is in the download, so it works in a basement, on a plane or at a festival with no signal at all. Signing in is optional and is the only thing in the app that ever uses a network.
How many people do I need?
Two is enough for about half the library, and most games are best with four to eight. Every game states its own range, and the app tells you when you need one more person rather than quietly leaving the game out.
Do we need one phone or several?
One phone is the default: it goes round the table. If you have several, they can join each other over Bluetooth or the same wifi — again with no internet — and then each person sees their own cards, their own role, or their own bingo ticket.
Can I use it with my family?
Yes. Every game ships fully playable at the mildest setting, which is the default, and that is where a new phone starts. A more personal tier exists for groups who want it and stays locked until somebody deliberately unlocks it in Settings.
Is it free?
Yes, and there is no advertising, no tracking and no analytics of any kind.
