Browser Demo vs. App
King Hub Witness operates as a web-based game. There is no separate application package, sideloading procedure, or native operating system integration confirmed by this guide. The game runs within the browser window, utilizing local storage for balance persistence.
- No Installation: Access is direct via the web interface.
- No APK: No verified mobile application package is provided.
- Local Storage: The wallet balance and fractional carry are saved locally; an active board is not saved and cannot resume after reload. No account login is required.
Game Mechanics & Layout
King Hub Witness is played on a 4×4 board. A fixed number of hazards are hidden in the grid. The layout is sampled uniformly from the published constraint support and remains fixed for the round.
Layout Rules:
- At least one hazard in the eight-neighbour king graph is adjacent to every other hazard.
- Other hazards do not need to be adjacent to each other.
Cell Identification: Cells are numbered row-major from 1 to 16.
Pricing & Probability
Each selected safe cell is priced from the exact posterior over consistent layouts. The gross value starts at 0.97 times the stake and updates as the board reveals information.
Value Calculation:
- Gross value becomes the current value divided by that cell's safe probability.
- Known-safe cells leave value unchanged.
- Proven hazards are disabled and cannot be selected.
Live Gross Quote: The live gross quote is calculated as 0.97 times the original support count divided by the surviving support count.
Controls & Modes
Stake: One whole stake is selected from 10, 20, 50, or 100.
Collection:
- Collection is available after at least one safe reveal.
- A click whose next gross multiplier exceeds 1,000 is rejected before reveal. The round stays active and unchanged; the cap does not disable the cell button.
- Automatic collection occurs only when no eligible uncertain move remains.
Settlement: If no uncertain cell remains after a safe pick, settlement is automatic. A hazard returns zero.
Wallet & Persistence
Initial Balance: 1,000 virtual coins.
Restoration: An idle balance below 10 manually restores the balance to exactly 1,000, preserving fractional change. This is a manual set, not automatic replenishment.
Fractional Carry: Fractional balance persists through settlement, manual refill, and reload.
Unfinished Rounds: An unfinished round ends without refund or resume upon reload. Settings and refill are locked while active.
