Board Mechanics & Support
Row No 101 uses a four-by-four board. The board is drawn uniformly from all configurations that satisfy a specific public support rule: no row contains the contiguous pattern 101. This constraint defines an exact finite board support. Draws are uniform over this support, not over all unconstrained boards.
After each safe reveal, the support filters. The gross quote is calculated as 0.96 × captured stake × initial support size ÷ current compatible support size. Known-certain mines are disabled, and cells with zero conditional safe probability are also disabled.
Payout & The 1000x Cap
The game features a gross payout cap of 1000 times the stake. If a safe reveal would exceed this cap, that cell is disabled. When no eligible reveal remains, the current quote is automatically banked.
The exact expected gross RTP is 0.96. Measured estimates from simulation may vary slightly from this exact value.
Controls & Modes
- Board Size: Four-by-four grid.
- Mine Count: Choices are limited to the exact nonempty support configurations in the source.
- Banking: Manual bank is available only after at least one safe reveal.
- Auto Queue: No auto queue; manual idle-only refill.
- Sound: Remains available throughout the round.
Wallet & Refill Rules
The initial balance is 1000 virtual coins. A manual refill sets the balance to exactly 1000 when the wallet is idle and below 10. This action preserves fractional carry. The wallet persists locally, including zero balances. An unfinished round ends without refund or resume on reload.
Privacy & Storage
Source uses browser localStorage for settled demo balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet; actual browser request capture is pending.
Responsible Use & Audience
This guide targets an 18+ audience policy, not a claim about local law or an implemented age gate. Virtual coins have no cash value. Responsible-use pages can describe optional pauses, a personal time/virtual-coin limit and finding appropriate local qualified help.
Frequently asked questions
What is the board structure and how are boards drawn?
The board is four-by-four. Boards are drawn uniformly from all configurations where no row contains the contiguous pattern 101. This defines an exact finite support.
How is the payout calculated?
Gross quote = 0.96 × captured stake × initial support count ÷ current compatible support count. The maximum payout is capped at 1000 times the stake.
What happens if I hit the 1000x cap?
Cells whose safe quote would exceed 1000 times the stake are disabled. If no eligible reveal remains, the current quote is automatically banked.
Can I bank manually?
Yes, but only after at least one safe reveal has occurred. There is no auto queue.
How does the wallet refill work?
When idle and the balance is below 10, a manual refill sets the integer wallet to exactly 1000. Fractional carry is preserved.
Is fractional carry preserved?
Yes, fractional carry persists across settlement, refill and reload.
What happens if I reload during a round?
An unfinished round ends without refund or resume. The settled balance persists locally.
What are the mine count options?
Mine count choices are only the exact nonempty support configurations in the source.
Is the RTP guaranteed?
The exact expected gross RTP is 0.96. Simulation measurements are supporting sample observations, not the mathematical payout law.
Does the demo use external services?
The template declares a Google Fonts stylesheet. This does not establish anonymity or exclude other processing.
Is this an official casino product?
No. This is an independent guide's demo. It does not certify or reproduce any outside product.
What is the intended audience?
18+ guide audience policy, not a claim about local law or an implemented age gate.
