No. Each BINGO5 drawing is independent, and past results cannot predict future winning numbers. The app is for enjoying statistics and AI commentary as entertainment and does not guarantee any winnings. It is an unofficial app with no affiliation with the lottery's issuers or sellers, and lottery tickets cannot be purchased in the app.

The center of the 3 x 3 grid is FREE, and each of the eight surrounding cells has its own fixed set of five candidates (A1 = 1-5, A2 = 6-10, A3 = 11-15, B1 = 16-20, B3 = 21-25, C1 = 26-30, C2 = 31-35, C3 = 36-40). You choose one number per cell, eight in total, and the prize tier depends on how many of the 8 lines (vertical, horizontal, diagonal) are completed. Please check the official lottery website for exact prizes and draw dates.

Hot Strategy (favors frequently drawn numbers), Cold Strategy (favors rarely drawn numbers), Pure Random (picks evenly from each cell's five candidates), Even-Odd Split (keeps the eight numbers at 4:4 even-odd), and Secret Algorithm (a blend of four analysis methods, unlocked by in-app purchase). Tap "Generate Prediction" to get five sets at once, one per strategy.

A score with a four-level label (Spicy, Balanced, Stable, Hotline likely) shown on each prediction card. It estimates how easily the eight chosen numbers would complete lines, based on past trends: each cell's appearance rate is multiplied along each of the 8 lines and summed (2 cells for lines through FREE, 3 cells otherwise). If every number appeared equally often, the value would be about 0.19. It does not guarantee a higher chance of winning.

The strategy used for the 5th set. It splits the eight cells into pairs and assigns each pair one of four methods: top frequency, lowest frequency, longest gap, and cycle detection. It is unlocked by a one-time in-app purchase (JPY 100 in Japan; local pricing elsewhere; not a subscription), with no further charges. Until purchased, the 5th set shows "?" and can be bought from its "Unlock" button.

iPhone: tap "Restore Purchases" in Settings (gear icon at the top right). It is restored if you are signed in with the Apple Account used for the purchase.
Android: with the Google account used for the purchase, it is restored automatically at launch. If it is not reflected, close and restart the app. If payment is pending (for example, cash payment at a convenience store), it is reflected after the payment completes.
If the problem persists, contact support@fujibit.com.

In-app purchases are processed by Apple (App Store) / Google (Google Play), so please request refunds through the store's own process. Once refunded, the "Secret Algorithm" is locked again at the next launch.

AI commentary uses Anthropic's Claude API and requires your own API key. Enter an sk-ant-... key in Settings and save. The key is stored only on your device, and only the statistics summary and predicted numbers are sent directly to Anthropic's API when commentary is generated. API usage fees are charged to the key owner. Predictions and statistics work normally without a key.

From a public CSV source (loto-life.net). Use the buttons below the header to switch the analysis range: Last 100, Last 500, All, or Custom (5 to 3000 draws). Without a connection, the app runs on a bundled sample of 40 draws.

An ad-removal purchase is not currently offered; ad revenue keeps the app free. The full-screen ad is never shown right after launch; it may appear only when you reopen the app from the background.

iPhone: change the app's tracking permission at any time in Settings > Privacy & Security > Tracking.
Android: reset or delete the advertising ID in Settings > Privacy > Ads, or Settings > Google > Ads (varies by device and OS version).
Every feature of the app remains available either way.

No account is required, and the developer runs no servers and does not collect your personal information. For ad delivery, the ad SDK (Pangle) sends information such as the advertising ID directly to the ad provider. See the Privacy Policy and Handling of Personal Information for details.

The app follows your device's language setting (Japanese / English). iPhone: Settings > General > Language & Region, or Settings > BINGO5 ORACLE > Language. Android: Settings > System > Languages (Android 13 and later also support per-app language settings).

iPhone (iOS 16 or later) and Android (8.0 or later). The latest version is 2.0.
