Independent guide
This independent Xvive guide supplies its own free Signal Stair Mines demo. Operator identity, domains, licence, apps, payments, support and commercial game equivalence have not been independently verified. No operator account or commercial link is supplied here.
External claims remain unverified
A matching brand, professional design, search result or HTTPS connection does not verify ownership, authorisation or safety. Match any claim against an independent regulator register, including entity, current status, scope and listed domains. No operator licence or service is endorsed here.
Technical requests and data limits
There are no account, payment or identity-document forms here. Fonts, the visit counter, server and CDN requests can expose technical data including IP and browser details. Complete anonymity, third-party data use and cookie lifetimes are not established. Clearing cache alone may leave localStorage intact.
Three occupied rows with distinct counts
Choose6,7 or8 hazards on a4×4 board. Exactly three rows contain hazards; their positive hazard counts are all different. The fourth row is empty. Counts are1/2/3 for6;1/2/4 for7;1/3/4 for8, in any row order. All2304/576/384legal layouts respectively are equally likely andfixed during a round.
Expected return and variance
Exact expected return is 97% for permitted stopping policies. The initial 3% reduction is applied once; conditional safe-branch compensation preserves expectation. Choosing coordinates or stopping changes risk and variance, not this expectation. A short session is not guaranteed to match it.
Persisted wallet and manual refill
Settled balance and fractional payout carry persist in localStorage. Reloading during a round ends it without refunding its already deducted stake. Outside a round, refill restores 1000 coins when balance is below the smallest stake; it does not add 1000 or reset fractional carry. Hazard count, stake and refill are locked during play.

What are the three occupied-row counts?
Choose6,7 or8 hazards on a4×4 board. Exactly three rows contain hazards; their positive hazard counts are all different. The fourth row is empty. Counts are1/2/3 for6;1/2/4 for7;1/3/4 for8, in any row order. All2304/576/384legal layouts respectively are equally likely andfixed during a round.
How is value calculated?
Live value starts at 0.97 times the virtual stake. A safe reveal divides it by that cell’s exact conditional safe probability among the remaining compatible legal layouts. A hazard ends the round with zero return. Reveals change knowledge, not the hidden layout.
