Scope of this independent guide
zbus.info publishes editorial pages and its own Queens on Open Cells browser simulator. A matching name or search query establishes no outside operator, official domain, licence, app, commercial catalogue, support contact or regional availability.
The simulator uses free virtual coins with no cash value. There are no deposits, withdrawals, commercial accounts or prizes here. Its results establish no external game mathematics, financial safety or commercial affiliation.
The actual simulator rules
One spin draws sixteen independent fair open/closed cells in a four-by-four board. Raw score counts complete placements of four queens on open cells, with exactly one queen in each row and column and no shared diagonal. The software counts all qualifying placements; the player does not choose a placement after seeing the board. One whole stake covers the board.
These are this guide's original rules. Visual resemblance, game-category names and search snippets provide no evidence about an external commercial game.
Worked scoring examples
A completely open board permits two placements and scores two. A board containing only its main diagonal scores zero. A board opening only columns [1,3,0,2] in rows zero through three permits one placement and scores one. Queen conflicts include both diagonal directions.
Limits of external claims
No outside business identity, official domain, commercial safety verdict, licence, financial service or support channel is authenticated here. A logo, search ranking, name or professional interface does not establish these facts. HTTPS encrypts transport to a selected host; it does not certify the host business.
The simulator cannot test external responsiveness, commercial payouts, accounts, funds or transactions. No commercial testing history, regulator endorsement or named editorial team with verified contacts has been established for these pages.
Local storage and external requests
The browser retains settled balance and fractional-credit carry as local game state. These records are not an online account and provide no recovery or device synchronisation service. Clearing site storage can remove them; cache deletion alone may not do so.
Pages request Google Fonts and a Statinside analytics script. Server/CDN logs and external requests may expose IP address, browser, device and request details. No anonymity, cookie lifetime, absence of profiling or complete third-party processing description is established. Having no personal-information form does not establish that browsing creates no personal data record.
Adult use and time boundaries
This guide and simulator are for adults aged eighteen or older. That is this website rule, not a determination of gambling eligibility, regional availability or local authorisation. Jurisdiction-specific questions require an authoritative local source.
Choose a stopping time outside the game, take breaks and leave when the time arrives. A free refill is optional, not an obligation to continue. If play crowds out other activities or feels difficult to stop, seek qualified local support; no diagnosis, symptom threshold or treatment claim is supplied here.
Frequently asked questions
Is this an authenticated operator website?
No. This guide provides its own simulator and authenticates no outside commercial affiliation.
How is raw score defined?
One spin draws sixteen independent fair open/closed cells in a four-by-four board. Raw score counts complete placements of four queens on open cells, with exactly one queen in each row and column and no shared diagonal. The software counts all qualifying placements; the player does not choose a placement after seeing the board. One whole stake covers the board.
What is an example of the score?
A completely open board permits two placements and scores two. A board containing only its main diagonal scores zero. A board opening only columns [1,3,0,2] in rows zero through three permits one placement and scores one. Queen conflicts include both diagonal directions.
What do the weighting modes change?
Low, Medium and High apply square-root, identity and square weights to a positive raw score. Zero stays zero, and each mode is separately normalised.
What does 96% describe?
Exact expected gross virtual return relative to captured stake under the stated probability condition. It is not a win probability or session guarantee.
