How we keep it honest
One friend. One guess. A sealed answer.
Spanda is a free game for one circle of up to five. Think of a friend, tap their name and send a mystery poke. The receiver locks one guess before the reveal. Each result sits next to what random picking would get.
The three-step play loop
- 01
Start a circle
Sign in with a magic link and create your circle.
- 02
Invite your friends
Invite up to four close friends to your private circle.
- 03
Tap a friend to start a round
Send a mystery poke by tapping a friend. The receiver guesses who sent it, with the guess locked before reveal. In the web app, after a correct guess, the two friends can choose to talk in a voice call.
Integrity mechanics
A friend chooses to reach out
The sender chooses whom to poke. 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.
Sealed sender
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.
Guess before reveal
The receiver commits one guess before the reveal. Correct and incorrect guesses both count.
An honest comparison
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.
What a score can and cannot say
Your score shows right guesses next to what random picking would get. It is a game score, not evidence of anything. Knowing who usually reaches out, luck and shared routines can all help you guess. Telepathy has not been established scientifically. Spanda does not claim it is real or test whether it exists.
