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.
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.
