Backgammon: Fair Dice & Nardy

Backgammon and long nardy with dice you can actually check. DICE YOU CAN CHECK Before each game the app seals the whole sequence of rolls and shows its fingerprint. You can add your own phrase, so the app cannot choose a convenient sequence in advance. After the game you get the key and can recompute every roll — in the app, on our website, or with any standard HMAC tool. The computer's level never touches the dice, and neither does any purchase.
