Send a symbol to a friend's mind. Guess the future door. Lock in a hunch before the outcome. MindLink turns classic parapsychology protocols into honest games — every trial is randomized, timestamped, and scored against chance, so you learn what your intuition can (and can't) do.

One sender, one receiver, four symbols. Share a 6-letter code and see if your partner picks up the signal — tracked live against the 25% chance baseline with real z-scores.
Invite a friend →Pick left or right — the winning side is generated by a cryptographic RNG only after you commit. Bet your confidence and build a personal calibration curve.
Play solo →Record a hunch before the outcome. Each entry is SHA-256 hashed and timestamped at lock — no editing after the fact, so a "called it" actually means something.
How it works →A classic sender/receiver signal-detection protocol. The sender focuses on a hidden symbol; the receiver guesses which of four it is. 25% is chance — everything above that is the interesting part.
Two doors. You commit to one, then a secure random generator
(crypto.getRandomValues) decides where the prize was. If anything in you can lean
on the future, this is the cleanest possible test — and if not, you'll watch a beautiful 50% baseline emerge.
Set your confidence on every trial. Scoring uses the Brier rule: honest confidence earns more points than bravado. A wrong guess at 100% sure scores 0; a wrong guess at 50% still scores 75.
Play Future DoorsEver "known" something before it happened, but only mentioned it after? The journal fixes the after-the-fact problem: write the hunch down before the outcome, and MindLink hashes it (SHA-256) with a timestamp at the moment you lock it.
Later, resolve it as a hit or a miss. Over time you get an honest ledger of your predictions — not the highlight reel memory keeps for you. Part of the iOS app, coming soon to the App Store.
Every game feeds one question: when you say 80%, are you right 80% of the time? MindLink bins your trials by stated confidence and plots observed accuracy against it.
Most people discover they're overconfident (bars falling short of the teal ticks, like this typical curve). Closing that gap is the core skill of good forecasting — useful long after you close the app.
MindLink is a game and a citizen-science tool for intuition, calibration, and connection. Telepathy and precognition are not established science — streaks happen by chance, and that's part of what you're learning to see.
Ganzfeld sender/receiver studies and presentiment meta-analyses have reported small above-chance anomalies, but large transparent replication projects have repeatedly failed to confirm them, and mainstream neuroscience explains anticipation through prediction, expectation, and learning — not information from the future.
So why play? Because the experimental protocols themselves are great training instruments. Every MindLink game is a real signal-detection task with honest baselines. Whether or not psi exists, you build skills that are unambiguously real:
Match your confidence to your actual accuracy — the core skill of good forecasting.
Watch yourself chase streaks and patterns in pure noise, and learn to catch it.
Practice quiet focus, first-impression trust, and partner connection.
Live z-scores and p-values against chance teach what "significant" really means.
