Step-by-Step Mark Proofs (Rule 1 & Rule 2)
DDT38 Big Eye Boy Entry #4

Column 3 has 2 beads. Column 2 has 2 beads. Same depth → red (=).

  1. Column 4 starts, so use Rule 1: compare Column 3 with Column 2, 1 column further back.
  2. Column 3 has 2 beads. Column 2 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 3, the one that just finished, with Column 2.

DDT38 Small Road Entry #4

Column 4 has 2 beads. Column 2 has 2 beads. Same depth → red (=).

  1. Column 5 starts, so use Rule 1: compare Column 4 with Column 2, 2 columns further back.
  2. Column 4 has 2 beads. Column 2 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 4, the one that just finished, with Column 2.

DDT38 Cockroach Pig Entry #2

Column 4 has 2 beads. Column 1 has 4 beads. Different depth → blue (≠).

  1. Column 5 starts, so use Rule 1: compare Column 4 with Column 1, 3 columns further back.
  2. Column 4 has 2 beads. Column 1 has 4 beads. Different depth → blue (≠).

Common table reading watchout: Comparing the wrong columns. Compare Column 4, the one that just finished, with Column 1.

Seed 204338 opening column signature: C1:4P · C2:2B · C3:2P · C4:2B · C5:2P · C6:2B · C7:2P · C8:2B.

DDT38 Big Road Span & Max Streaks
Max 4B / Max 4P Across 32 Logical Cols (32 Display Cols)

In a 2-by-2 twin run, the first bead of each pair triggers Rule 1 at Row 1 (comparing prior depth 2 against depth 2) and the second bead triggers Rule 2 Case 1 at Row 2.

DDT38 Big Eye Boy Rule Breakdown
63 Marks (27R / 36B · 42.9% Red across 26 Display Cols)

DDT38 Small Road & Cockroach Pig Tally
SR: 29R/32B (47.5% Red) · CP: 46R/13B (78.0% Red)

When a column finally extends to a third bead at Row 3, it steps exactly one row past the reference column's depth-2 stop point, producing a textbook Rule 2 Case 2 Blue (≠) break.

DDT38 DERIVED-ROAD & CUT-CARD PROBE

DDT38 Lookback Split (27R/36B BEB · 29R/32B SR · 46R/13B CP)

When a column finally extends to a third bead at Row 3, it steps exactly one row past the reference column's depth-2 stop point, producing a textbook Rule 2 Case 2 Blue (≠) break. Across DDT38, Big Eye Boy prints 27 Red (42.9%) and 36 Blue marks, Small Road prints 29 Red (47.5%) and 32 Blue marks, and Cockroach Pig prints 46 Red (78.0%) and 13 Blue marks.

At the DDT38 cut card after Hand #73, probing Hand #74 via getNextRoadPredictions() yields Banker → BEB RED / SR BLUE / CP RED and Player → BEB BLUE / SR RED / CP BLUE for DDT38.

Table Reality Check

Myth vs. Truth

MythThe second bead of each pair in DDT38 marks Blue because the 2-bead column is about to end.
TruthAt Row 2 in DDT38, the reference column also has a bead at Row 2, so Rule 2 Case 1 marks Red (=); a break only appears if a column stops at 1 or extends to Row 3.
