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.

Frequently asked questions

Is Seinlucky a verified operator?

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.
