What this guide offers
This guide explains an original constrained-board game and lets you try it with virtual coins. The companion pages cover browser use, the local wallet, privacy observations and practical limits. Their scope is this website’s demonstration.
The original demonstration
The board has 16 cells, numbered left to right across four rows. Choose 3, 4 or 5 hazards before starting. The game samples one complete layout uniformly from 68, 72 or 24 permitted layouts, respectively. That layout stays fixed throughout the round.
Safe cells connect through horizontal or vertical neighbours. They must remain connected even if any single safe cell is removed. This constraint changes the chances from those of an ordinary board with independently placed hazards.
How picks change the chances
Each cell displays its conditional chance of being safe among layouts compatible with the revealed safe cells. Percentages are rounded to one decimal for display; the calculation uses the full ratio. Already revealed cells, proven safe cells and proven hazards are disabled.
The gross multiplier is 0.97 × original layout count ÷ remaining layout count. It starts at 0.9700×. A safe pick divides the previous multiplier by that cell’s safe chance. A hazard ends the round with zero returned coins.
Settlement and limits
After at least one uncertain safe pick, Collect returns the current gross value. A safe pick that leaves no uncertain cells triggers automatic collection. Stake and hazard settings, restoration and a second start are locked during play; sound remains available.
Settlement credits the whole-number part of stake × multiplier + saved fractional carry and saves the remainder for later rounds. The multiplier includes the stake; it is not a profit multiplier. A losing round returns zero and preserves the saved fraction.
Outside identity and services
This is an independent guide using the search name 7JJ and offering its own original browser demo. The name and domain alone do not establish a company, licence, ownership, official address, business history or affiliation. The demo does not certify or reproduce an outside product.
No official app, APK, cashier, support channel, bonus, account recovery process or outside service has been verified here. Descriptions and assessments on these pages concern this guide and its demo.
The code includes a guard against a prospective multiplier above 1,000×. However, these supported layouts can reach at most 65.96×, 69.84× and 23.28× for 3, 4 and 5 hazards. The guard is therefore unreachable in this demo and does not set an attainable target or protect a stake from loss.
Audience and data
The guide is intended for adults aged 18 and over as its own audience policy. The interface has no age verification, and this label is not a statement about the legal age or legality in any location.
Virtual coins make the demonstration free to use; they do not make every pattern of use harmless. You can choose a personal time or coin limit and stop without restoring the wallet. The demo does not enforce timers, spending limits or account exclusion.
The demo stores virtual balance and fractional carry in localStorage. Pages request Google Fonts, and the site uses the Statinside visitor counter with account 44. The counter requests and font loading involve network connections outside the local wallet.
These observations do not establish anonymity or a complete account of server logs, retention, tracking, data sale or further processing. The absence of account and payment forms does not mean that no personal data are processed. No privacy policy for an outside 7JJ service has been verified.
Frequently asked questions
Is this an official 7JJ app or account service?
No official status or outside service has been verified here. This independent guide offers its own browser demo without sign-in, deposits or withdrawals.
Does the layout change after a pick?
No. One permitted layout is sampled at Start and stays fixed for that round.
Is 97% a guaranteed return?
No. It is the expected gross return under the uniform-layout model, not a win probability or promised session result. An abandoned round forfeits its possible return.
