Backgammon True Dice vs Backgammon Online with Friends

Backgammon you can check. Every backgammon app says its dice are random. This one lets you prove it. Before your first move, Backgammon True Dice generates a random 32-byte seed and shows you its SHA-256 fingerprint, right there on the board. Every roll of the game is derived from that seed, so the whole sequence is fixed before you make a single decision. When the game ends, the seed is revealed and the app replays every roll in front of you. Copy the seed, the fingerprint and the roll journal, and you can repeat the calculation with any tool you like. The opponent never sees the seed. It receives the board and the roll that has already happened — nothing else. Difficulty changes how deeply it thinks, never what you roll. TWO GAMES ON ONE BOARD • Backgammon — opposing tracks, hitting, the bar, gammons and backgammons • Long nardy — one direction, no hitting, one checker off the head per turn, mars PLAY YOUR WAY • Three opponent levels, from a relaxed game to a genuinely hard one • Two players on one device, passing it back and forth • Take back a whole turn until you confirm it • Legal moves highlighted, so the rules never get in the way SEE THE DICE FOR YOURSELF • The game fingerprint stays visible on the board while you play • Full roll journal, including the rolls that decided who starts • A histogram of all 36 outcomes for you and your opponent, against what fair dice would give • Journals of your last twenty games, so you can check a suspicion days later BUILT TO BE QUIET • Works entirely offline, in airplane mode, on a plane or underground • No account, no sign-in, nothing to set up • Not a single system permission requested — no contacts, no location, no notifications • Nothing is collected: no analytics, no tracking, no networking code at all Backgammon and long nardy are traditional games with centuries of history. This app adds one modern thing to them: dice you do not have to take on trust.

Backgammon against a real person — and you can hear them. At a table joined by an invite code you see their face too. The dice are fair: the game seed is on the table and every roll can be recomputed. No coins, no banners, no sign-up. VOICE AND FACE AT THE TABLE At an online table you can talk. The microphone is asked for once, when you sit down; say no and nothing else changes — the game simply goes on in silence. Video is switched on with a button and only at a table joined by an invite code, that is, between people who know each other; the camera is off by default. You can mute your opponent, report them, and never be matched with them again. GLASS DICE Every roll is computed from the game seed (HMAC-SHA256). The seed is shown on the table; “Verify” recomputes every die. Face, doubles and luck statistics for you and your opponent. No rigged dice, ever. BACKGAMMON AND THREE MORE RULE SETS • Backgammon: hitting, the bar, the doubling cube, the Crawford rule, gammon and backgammon. • Long nardy: the head, the 6-6/4-4/3-3 first-move exception, the six-block rule, mars and koks. • Tavla and Shesh Besh presets. Matches to 3, 5 and 7 points. A CHAMPION-LEVEL COACH Hints show the best play; the post-game review shows where points were lost. In backgammon the evaluation comes from a neural net stronger than GNU Backgammon, on your phone, offline. HONEST OPPONENTS Six bot characters from novice to master, always labelled. No fake “humans”. Two players on one phone. ONLINE WITH LIVE PLAYERS Find an opponent by rating or play a friend with a table code. Online dice come from the arbiter: the seed hash is shown to both before the first roll, and after the match the seed is revealed so every roll can be recomputed. Elo rating and a top-100 table — only for matches against real people. NO COINS, NO BANNERS Nothing you can buy makes you stronger. The Store screen holds Pro, three boards sold separately, and tips. Pro unlocks board themes, unlimited hints and the full luck history. Tips (“Support the yard”) unlock nothing — they are just a thank-you. The whole game is free. No banners and no ads mid-game — just a short video between games, and Pro or any purchased board turns it off. Any board can be tried on for a day for one video. ONE HAND Portrait board, tap a checker and tap a point, two-dice jumps in one tap, auto-move when there is no choice. Works offline. No sign-up. Interface in 19 languages.
