Why We Are Not the Official 28Z Site
28Z is the search name discussed in this independent guide. We have not verified an external operator, its official domain, licence, account system, payments or apps. The game on 28z.info is our own free simulator; its rules and 97% theoretical return describe only this simulator. No equivalence to another service is established. This guide has no accounts, deposits, withdrawals or cash prizes.
Our Editorial Approach: Facts vs. Simulations
Twelve independent fair bits are sampled once at round start and revealed one per second. They mark the 12 edges between three left vertices A/B/C and four right vertices 0/1/2/3, in order A 0,A 1,A 2,A 3,B 0,...,C 3. Bit 1 opens an edge;0 closes it. Terminal reward is 1 if all seven vertices have at least one open incident edge, otherwise 0. This is coverage, not a connected-path requirement. Exactly 2161 of 4096 complete layouts cover all vertices; initial expected reward 2161/4096. Quote=0.97×exact conditional coverage probability÷(2161/4096), and may rise or fall. Allknown-covered vertices fix maxquote 0.97×4096/2161≈1.838556224. Auto 2/3/5 cannot trigger; final settlement applies. Collect initially at 0.97 or after a reveal, or preselect automatic 1.2/1.5/2/3/5. The first upward crossing pays the full actual quote. A vertex with all incident edges closed proves failure and ends immediately; reveal 12 settles automatically. Every revealed-information stopping policy has exactly 97% expected gross return, not 97%winchance or guaranteed balance. Hidden bits are never resampled while quoting. Wallet and fractional credits persist after reload. Idle balance below 10 may be restored to 1,000 free coins.

Privacy and Technical Details
The simulator stores only its virtual balance and fractional credits locally. There is no account, deposit or identity form here. Google Fonts and Statinside analytics make third-party requests. Server/CDN logs and those requests may expose IP addresses, device and request information. Anonymity and specific cookie lifetimes have not been verified. Clearing cache alone may leave localStorage intact; use the browser’s site-data controls to remove it.
