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.
Captured settings and the persisted wallet
A new browser wallet starts with 1,000 free virtual coins. Settled balance and fractional-credit carry persist in localStorage. Reload does not replenish settled funds; clearing cache may leave localStorage intact. Fractions accumulate before whole coins are credited.
A spin captures one whole stake and mode. Controls and refill lock during settlement and an active automatic queue. Auto launches at most ten rounds; Stop cancels future launches while active results settle. Refill remains locked until all active results and queued launches finish. Optional manual refill is available while idle with balance below ten; it sets balance to 1,000 and preserves carry. It is not automatic and does not add 1,000.
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.
