Bac Bo is baccarat played with dice: two dice a side, higher total wins, equal totals tie. Bac Bo Stat Master is the statistics tool for it. You record the rounds; it does the counting, the roadmaps and the arithmetic. IMPORTANT: This is not a gambling app, not a betting app and not a real-money game. It takes no deposits, bets, wagers or withdrawals, holds no balance, wallet or credits, and pays out no money, prizes or rewards. It links to no casino or betting operator and cannot influence any real-world outcome. WHAT DICE GIVE YOU A baccarat hand gives you a winner. A Bac Bo round gives you a winner and two totals, 2 through 12, and every tie lands on a total of its own. So alongside the roadmap you know, this app tracks the numbers the table rolled. • Side-total heat across the whole 2 to 12 range • Tie-total heat: which totals the ties are landing on • Sample size shown next to both, so a thin reading cannot look strong Enter a round three ways: Tap to set each die face, Pick to choose from a list, or Board to tap Player, Tie or Banker when you only caught the result. Undo removes the last round; New starts a fresh shoe. Modes: Mirror, Flow Reader Two engines read the same shoe through different lenses, so they can legitimately disagree. • Mirror reads the bead-road column mirror: does each result match the one six hands earlier, and is that mirror holding or flipping • Flow Reader reads the immediate sequence: does the shoe repeat or alternate, and what followed the last two results Follow the shoe on a Live Road with ties marked in place, then switch the same session to a candle or line chart. Counters track rounds, Player, Banker and Tie percentages, and the current streak. No signal appears for the first 7 rounds, because a handful of rounds is not a sample. When one does, it carries a strength value and the reasoning behind it, so you can see why the app said what it said and disagree with it. Rounds are independent. No drought and no payout size makes any total more likely, and the app never pretends otherwise. BUILT FOR EVERYDAY USE iPhone and iPad, portrait and landscape. Dark, light and system themes. 16 languages. No account, no sign-in, no ads. PRIVACY • Every analysis engine runs on your device, so the analysis works offline • Your rounds stay on your device and go to no third-party AI service • No account needed for core use; no wallet, balance or payment data exists • The only network calls: the App Store for subscriptions, our own server for the free daily allowance and purchase checks, and crash diagnostics FREE AND PREMIUM Free use gives you 10 signals a day, no account. Premium removes that daily cap. The roads, the charts, the heat grids and both analysis modes are available to everyone, free. • Premium Monthly: one month, auto-renewing • Premium Yearly: one year, auto-renewing Prices vary by country and are shown in your currency before you confirm. Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for the renewal within 24 hours before the period ends. You can manage or cancel subscriptions in your Apple Account settings after purchase. A subscription unlocks app features only and carries no cash value, credits, rewards, prizes or wagers. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://bacbo-stat-master.web.app/privacy-policy.html DISCLAIMER Bac Bo outcomes are statistically independent. Every signal or statistic is a mathematical study estimate from the results you entered. It is not betting advice, not a winning method and not a guarantee of any outcome. Past results do not predict future rounds. For education, statistics, simulation and research by adults 18+. You are responsible for the laws where you live. Support: apps3mb@gmail.com
