No login here
This site has no registration or login form. The demo needs no account; operator authentication and password-recovery flows are unverified. Do not enter credentials into an unverified page.
Unverified destinations
Do not share passwords or one-time codes with unsolicited contacts. A similar domain or HTTPS certificate does not establish the destination’s identity. No example operator login domain is supplied or endorsed here.
Unconfirmed recovery
Use only documented recovery procedures from a service whose identity has been independently established. No support contact, response time, reset-token lifetime or 2 FA feature has been verified here.
Checking external claims
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.
Two even coordinate sums
Choose 3, 4 or 5 hazards on a 4×4 board. Number rows and columns from 0 to 3, top to bottom and left to right. Add the row indices of all hazards and, separately, their column indices. Both sums must be even. Individual indices need not be even, and this does not require an even hazard count in every row or column. All 140, 476 or 1092 legal layouts respectively are equally likely; one stays fixed throughout the round.
Wallet and restoring balance
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.
Technical data
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.
Frequently asked questions
Is this an operator website?
This independent XOTOTO guide supplies its own free Even Coordinates 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.
What are the coordinate sum rules?
Choose 3, 4 or 5 hazards on a 4×4 board. Number rows and columns from 0 to 3, top to bottom and left to right. Add the row indices of all hazards and, separately, their column indices. Both sums must be even. Individual indices need not be even, and this does not require an even hazard count in every row or column. All 140, 476 or 1092 legal layouts respectively are equally likely; one stays fixed throughout the 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.
