The Full Hosted Platform
When subscriptions launch, the hosted platform will add cloud sync, QR verification, multi-device support, and cryptographically verifiable transparency reports.
1 Plan Your Night
Set your games, sheet prices, and prize plans in the web dashboard. The rules engine ensures compliance with your jurisdiction's regulations and that all money balances correctly.
2 Print QR-Verified Sheets
Print unique tickets with QR codes that link to your venue's subdomain. Each QR code opens a player page showing their sheet, the calls so far, and their results.
3 Call the Game
Use the caller screen to draw numbers. Before the first call, a cryptographic seed is generated and its fingerprint published. The complete draw order is fixed at that moment but kept secret until the game closes - proving draws are fair and predetermined.
4 Check Claims Instantly
Scan the QR code or type the sheet ID to verify claims. The system shows exactly which call completed their line or full house, and whether the claim is valid.
5 Publish Transparency Reports
At the end of the night, an automatic report shows every game, every payout, and proves the balance: takings + money brought in = prizes paid + money held + house share. The seed is revealed so anyone can verify the draws were truly predetermined.
What Makes It Different
Cryptographically Provable Draws
The complete draw order is fixed before the first call using a cryptographic seed. The fingerprint is published immediately. At the end of the game, the seed is revealed so anyone can verify the draws matched the pre-committed order.
Append-Only Records
Every event is recorded in an append-only log with cryptographic hash chaining. Records cannot be edited or deleted - corrections are new visible entries.
Automatic Balancing
Every report shows the balance equation: stakes + money in = paid out + held + house share. The system ensures this always holds before publishing.
Works Offline
If your internet drops, the night continues from the commit seed and cached Georgia K voice. Closed nights stay in the on-device archive; when cloud sync is connected they can publish to the API. On a phone, add Bingo Caller to the home screen from your browser menu so Setup opens in one tap with the voice pack cached.
