Step-by-Step Mark Proofs (Rule 1 & Rule 2)
DDT31 Big Eye Boy Entry #3

This bead is at Row 2. Column 2 has a bead at Row 2 too → red (=).

  1. Column 3 goes down to Row 2, so use Rule 2: look 1 column back, at Column 2.
  2. Column 2 has a bead at Row 2 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 2 stopped exactly one row above this bead.

DDT31 Small Road Entry #2

Column 3 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

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

Common table reading watchout: Comparing the wrong columns. Compare Column 3, the one that just finished, with Column 1.

DDT31 Cockroach Pig Entry #3

This bead is at Row 2. Column 2 has a bead at Row 2 too → red (=).

  1. Column 5 goes down to Row 2, so use Rule 2: look 3 columns back, at Column 2.
  2. Column 2 has a bead at Row 2 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 2 stopped exactly one row above this bead.

Key Facts & Table Specifications

DDT31 8-Deck Hand Distribution
74 Hands (36 Banker / 30 Player / 8 Tie)

Seed 204331 opening column signature: C1:2B · C2:2P · C3:2B · C4:2P · C5:2B · C6:2P · C7:2B · C8:1P.

DDT31 Big Road Span & Max Streaks
Max 4B / Max 4P Across 31 Logical Cols (31 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.

DDT31 Big Eye Boy Rule Breakdown
63 Marks (27R / 36B · 42.9% Red across 32 Display Cols)

Rule 1: 29 marks · Rule 2 Case 1: 0 · Case 2: 0 · Case 3: 34.

DDT31 Small Road & Cockroach Pig Tally
SR: 27R/34B (44.3% Red) · CP: 43R/16B (72.9% 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.

DDT31 DERIVED-ROAD & CUT-CARD PROBE

DDT31 Lookback Split (27R/36B BEB · 27R/34B SR · 43R/16B 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 DDT31, Big Eye Boy prints 27 Red (42.9%) and 36 Blue marks, Small Road prints 27 Red (44.3%) and 34 Blue marks, and Cockroach Pig prints 43 Red (72.9%) and 16 Blue marks.

At the DDT31 cut card after Hand #74, probing Hand #75 via getNextRoadPredictions() yields Banker → BEB RED / SR RED / CP BLUE and Player → BEB BLUE / SR BLUE / CP RED for DDT31.

Table Reality Check

Myth vs. Truth

MythThe second bead of each pair in DDT31 marks Blue because the 2-bead column is about to end.
TruthAt Row 2 in DDT31, 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.
