Verify the seal
A sealed mystery commits its solution — a SHA-256 hash — before you play. After the reveal, paste it here. Your browser recomputes the hash and, if it matches, the seal turns green: proof the answer was fixed in advance. Nothing is sent anywhere.
VerifierPaste a reveal and its commitment, then check the seal.
Audit a dice tape
Dice games don't let the AI invent rolls — they read a published d20 tape generated from
a fixed seed ({game}:{version}). Pick a game to regenerate its
tape here in your browser; it must match the tape printed in the card, roll for roll. Check
a single position too — if your game master shows tape#14=17, this confirms it.
