Enter a 3-digit seed (e.g., 128). The tool builds the grid with the mirror map (0↔5, 1↔6, 2↔7, 3↔8, 4↔9), shows all 8 line numbers, and suggests the top 3.
Grid
Formula recap: Top = (c, m(c), m(c)) · Middle = (m(c)+1, a, b) · Bottom = (m(mid-left), m(mid-left), m(b)) with m(d)=(d+5) mod 10.

Top 3 Most Likely (Heuristic)
Scoring favors lines that include seed digits (a,b,c) or mirror(c), reward clean singles and one-double patterns, and lightly boosts sums in the mid range. Tweak the weights in code if you want it more aggressive.
