What Indian Players Should Check
Before switching from the free demo to real play, you must verify the financial and legal setup for ka9. Confirm if the brand accepts INR for deposits and withdrawals, as this avoids currency conversion fees. Check if they support popular Indian payment gateways such as UPI, Paytm, or PhonePe, and learn how to verify these options in the cashier section of the official ka9 site.
- Regulation: Gambling legality in India depends on the specific state you reside in. Some states ban online gaming, while others allow it. You are responsible for checking your local laws.
- Safety: Look for SSL encryption on the official site. Read the terms and conditions regarding withdrawal limits and verification (KYC) processes.
- Age: Ensure you are 18+ or the legal age in your state.
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.
- Individual prospective values above 1,000× the original stake are disabled.
- 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.
