Three rows and four columns
Twelve independent fair binary choices determine occupied cells on a3-row,4-column board. The software selects the largest orthogonally connected occupied component; diagonal contact does not connect cells. If several components tie in size, it selects the component containing the earliest cell in row-major order: top row left to right, then the next row. The player does not choose cells or the component.
A straight component of three cells has exposed perimeter8. A filled2×2 square also has perimeter8. A completely filled3×4 board scores14. One-cell and two-cell components score0 despite having exposed edges. Size ties use the earliest row-major cell, rather than selecting whichever tied shape has a larger perimeter.
The score histogram for raw scores0,8,10,12,14,16,18,20 is803,816,814,646,516,312,156,33 patterns respectively. These counts sum to4096;3293 patterns have positive gross credit. Positive credit is not necessarily profit after subtracting the stake. Linear, square and cube weighting preserve which boards have positive scores and which have zero scores.
Exposed edges after the size threshold
A selected component with fewer than3 cells scores0. Otherwise its raw score is the number of exposed horizontal and vertical cell edges, including edges on the board boundary. Shared edges inside the component are not exposed. This is a perimeter count, not the number of cells, not the combined perimeter of all components, and not a Mines reveal or cash-out decision.
Powers with three distinct exact means
For p=1,2,3, the gross-credit multiplier is0.96 × score^p / mean(score^p). The exact means are9.302734375,115.087890625,1517.51171875 respectively. Each mode therefore has expected gross credit96% of the captured stake. Powers do not multiply by2 or3, and they do not change the generated score distribution or positive-credit frequency. The96% expectation is neither a winning probability nor a final-wallet guarantee.
The finite virtual wallet
A new browser wallet starts at 1000 virtual coins. Settled integer balance and fractional payout carry are saved in localStorage. A gross credit is added to any saved fraction; the integer part is credited and the remaining fraction is carried forward. These coins have no cash value, deposits, withdrawals or prizes. Storage belongs to this browser and origin, not to an account or an external payment balance.
Only an idle balance below ten offers Free refill. Clicking it sets the balance to 1000; it does not add 1000 to the existing balance. The fractional carry is preserved. Refill is unavailable during settlement or an active automatic queue. Changing the stake cannot force a refill while the balance is ten or more. A previously saved zero balance remains zero after reload until the user clicks the available refill.
Requests and privacy limits
The game needs no login or personal-data form. That does not mean no personal data is processed. Pages request Google Fonts and a Statinside counter; hosting, CDN and third-party requests may expose IP addresses, device information, URLs and request times. Exact retention periods, cookie lifetimes, linking practices and anonymity have not been independently established here. We make no promise that technical data cannot identify or be linked to a person.
No legal eligibility verdict
The interface is intended for people aged 18 or older. This site restriction is not a statement of a universal legal gambling age, a licence or permission to use another service. Any question about a particular real-money activity requires current local law and the exact facts about the service and user. This guide has not verified those facts and does not give legal advice.
Choose before the whole-board draw
Choose stake and weighting before Draw. One captured stake is debited for the whole board; there are no rows of separate stakes or paylines. A round settles in480milliseconds. Settings and refill lock during settlement and an active Auto queue. Auto schedules up to10 rounds when balance permits. Stop cancels future rounds only, without cancelling or refunding the current round.
Frequently asked questions
Is Seinlucky a verified operator?
Seinlucky is a search topic on this independent guide. A matching name or domain does not establish a business, official application, licence or payment service. We have not verified an operator, official address, financial offering or support channel. Boundary Ribbon is our own virtual-coin simulator with its own mathematics; it is not a commercial replica or a test of an external service.
Who selects the component?
Twelve independent fair binary choices determine occupied cells on a3-row,4-column board. The software selects the largest orthogonally connected occupied component; diagonal contact does not connect cells. If several components tie in size, it selects the component containing the earliest cell in row-major order: top row left to right, then the next row. The player does not choose cells or the component.
Which edges count toward the score?
A selected component with fewer than3 cells scores0. Otherwise its raw score is the number of exposed horizontal and vertical cell edges, including edges on the board boundary. Shared edges inside the component are not exposed. This is a perimeter count, not the number of cells, not the combined perimeter of all components, and not a Mines reveal or cash-out decision.
What does a completely filled board score?
A straight component of three cells has exposed perimeter8. A filled2×2 square also has perimeter8. A completely filled3×4 board scores14. One-cell and two-cell components score0 despite having exposed edges. Size ties use the earliest row-major cell, rather than selecting whichever tied shape has a larger perimeter.
Is96% the chance of profit?
For p=1,2,3, the gross-credit multiplier is0.96 × score^p / mean(score^p). The exact means are9.302734375,115.087890625,1517.51171875 respectively. Each mode therefore has expected gross credit96% of the captured stake. Powers do not multiply by2 or3, and they do not change the generated score distribution or positive-credit frequency. The96% expectation is neither a winning probability nor a final-wallet guarantee.
Can settings change during a round?
Choose stake and weighting before Draw. One captured stake is debited for the whole board; there are no rows of separate stakes or paylines. A round settles in480milliseconds. Settings and refill lock during settlement and an active Auto queue. Auto schedules up to10 rounds when balance permits. Stop cancels future rounds only, without cancelling or refunding the current round.
When is free refill available?
Only an idle balance below ten offers Free refill. Clicking it sets the balance to 1000; it does not add 1000 to the existing balance. The fractional carry is preserved. Refill is unavailable during settlement or an active automatic queue. Changing the stake cannot force a refill while the balance is ten or more. A previously saved zero balance remains zero after reload until the user clicks the available refill.
What happens if I reload before settlement?
Reload preserves saved balance and fractional carry when browser storage remains available. A draw debits its stake before the short settlement animation: leaving or reloading during that unfinished animation can discard its pending credit. Reload after settlement preserves the completed result. Clearing cache alone may not delete localStorage; removing site storage can erase the wallet. Private browsing and browser settings can change storage availability and retention.
Does having no account guarantee anonymity?
The game needs no login or personal-data form. That does not mean no personal data is processed. Pages request Google Fonts and a Statinside counter; hosting, CDN and third-party requests may expose IP addresses, device information, URLs and request times. Exact retention periods, cookie lifetimes, linking practices and anonymity have not been independently established here. We make no promise that technical data cannot identify or be linked to a person.
Does18+ establish legal permission?
The interface is intended for people aged 18 or older. This site restriction is not a statement of a universal legal gambling age, a licence or permission to use another service. Any question about a particular real-money activity requires current local law and the exact facts about the service and user. This guide has not verified those facts and does not give legal advice.
Does weighting change positive-result frequency?
The score histogram for raw scores0,8,10,12,14,16,18,20 is803,816,814,646,516,312,156,33 patterns respectively. These counts sum to4096;3293 patterns have positive gross credit. Positive credit is not necessarily profit after subtracting the stake. Linear, square and cube weighting preserve which boards have positive scores and which have zero scores.
What can the simulator evidence prove?
The4096-board enumeration checks Boundary Ribbon and its stated payout formula only. It does not certify an outside random generator, prove a licence, assess an application, establish privacy or demonstrate an external service’s ability to pay. We give no commercial audit, regulatory approval, legitimacy verdict or general safety guarantee for the entity someone intended to find.
