You thought about them. Now they get to guess.
Spanda: the guess-who-poked-you game for close friends.
Spanda is a free guessing game for you and up to four close friends. Think of a friend, open Spanda, tap their name and send a mystery poke. They lock one guess at who sent it before the reveal. Your score sits next to what random picking would get. Spanda 1.0 is available on the App Store for iPhone and also works in your browser.
One circle of up to five. Magic-link sign-up. No payment. No belief required.
You know the feeling
Ever been thinking about a friend, and they call?
You picture someone, and moments later they send you a message. Small coincidences like that can make a day feel warmer.
Spanda takes that familiar feeling and turns it into a game you can share with close friends.
Someone on your mind? Give them a little mystery to guess.
Start a private circle, invite up to four close friends, and make a little room for each other in your day.

Spanda · a small moment of attention
A simple game: think of a friend, send them a mystery poke, and let them guess it was you.
Spanda is a Sanskrit word often translated as a subtle pulse, vibration, throb, or movement of life. We chose it because this game is about tiny felt signals: not grand claims, not thunderbolts.
The small pulse before the phone lights up. The name that arrives before the notification. The sense that someone is near in attention before they appear on the screen.
We're not asking you to believe a doctrine, just to notice, play, guess, record, and see.
One poke. One guess. One reveal.
Think of a friend. Give them a guess.
One free circle of up to five people. Every round starts with a tap on a friend.
- 01
Tap a friend
Someone on your mind? Tap their name. They get a mystery poke that does not say who sent it.
- 02
The answer is sealed
Before your friend guesses, a hash commitment seals who sent the poke. A changed answer would not match that fingerprint.
- 03
Lock in your guess
Your friend picks who they think sent it, and their guess locks before the reveal. Right or wrong, it goes on the board. In the web app, after a correct guess, the two friends can choose to talk in a voice call.
Your score
A little friendly guessing
Right guesses next to what random picking would get. A game score, not evidence of anything.
Illustrative score with four possible senders each round, not a real person’s result.
The idea and its limits
Spanda is a private game for close friends. The sender chooses whom to poke. Knowing who usually reaches out can help you guess without anything unusual going on. Spanda may send a gentle reminder to think of a friend. A reminder never starts a round: you choose a friend and tap their name to send a poke.
Curious, careful, and allergic to pretending.
Spanda is a playful game inspired by telephone-telepathy stories. Telepathy has not been established scientifically. Spanda does not claim it is real or test whether it exists.
In a full circle of five, random picking would get one in four guesses right (25%). Spanda works out the comparison for each round from who could have sent the poke. It is a game score, not evidence of telepathy. Read about the inspiration and why the game cannot test those stories.
The wider scientific consensus remains that telepathy has not been established.
Knowing who usually reaches out, luck, habits and shared routines can all help you guess. A score is part of the game, not a scientific finding.
Sealed answers. Locked guesses.
The sender chooses the friend. The commitment records who sent the poke before that friend guesses.
- 1Sender sealed before the guess
- 2A changed answer would not match the published fingerprint
- 3Guess locked before the reveal
- 4Random-picking comparison worked out from the possible senders
- 5Correct and incorrect guesses both count
If you choose to hide who sent a poke after a miss, the identity and the secret that opens the seal stay hidden.
The Mark
Two arcs. One signal. A gap that matters.
The arcs reach toward each other, but never close. The dot is the moment of attention between them.
Connection is not possession.
Intuition is not certainty.
A hit is not a verdict.
Fair questions
Straight answers. No mystic sales pitch.
Are you saying telepathy is real?＋
No. Telepathy has not been established scientifically. Spanda does not claim it is real or test whether it exists. Knowing who usually reaches out, luck and shared routines can all help you guess.
Can Spanda tell me who I should trust?＋
No. Spanda is a game, not a clinical, therapeutic, diagnostic, relationship, or decision-making tool.
What happens when I miss?＋
Correct and incorrect guesses both count. You can choose whether to see who sent the poke after a miss.
How are answers sealed?＋
The sender is sealed with a hash commitment before the guess. Changing the sealed answer would make it fail to match the published fingerprint. Your guess locks before the reveal. If you choose to hide the sender after a miss, that identity and the secret that opens the seal stay hidden.
Why up to five people?＋
A free circle holds up to five people. In a full circle of five, random picking would get one in four guesses right (25%). Spanda works out the comparison for each round from who could have sent the poke. It is a game score, not evidence of telepathy.
Does it cost anything?＋
Spanda is free: organise one circle of up to five people and join your friends' circles. A Host upgrade for bigger circles and more of them is coming to the iPhone app. Friends you invite will always play free.
