Step-by-Step Mark Proofs (Rule 1 & Rule 2)
DDT12 Big Eye Boy Entry #8

Column 5 has 2 beads. Column 4 has 2 beads. Same depth → red (=).

  1. Column 6 starts, so use Rule 1: compare Column 5 with Column 4, 1 column further back.
  2. Column 5 has 2 beads. Column 4 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 5, the one that just finished, with Column 4.

DDT12 Small Road Entry #3

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

  1. Column 4 goes down to Row 2, so use Rule 2: look 2 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.

DDT12 Cockroach Pig Entry #4

Column 5 has 2 beads. Column 2 has 2 beads. Same depth → red (=).

  1. Column 6 starts, so use Rule 1: compare Column 5 with Column 2, 3 columns further back.
  2. Column 5 has 2 beads. Column 2 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 5, the one that just finished, with Column 2.

DDT12 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.

DDT12 Big Eye Boy Rule Breakdown
62 Marks (28R / 34B · 45.2% Red across 26 Display Cols)

DDT12 Small Road & Cockroach Pig Tally
SR: 31R/29B (51.7% Red) · CP: 46R/12B (79.3% 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.

DDT12 DERIVED-ROAD & CUT-CARD PROBE

DDT12 Lookback Split (28R/34B BEB · 31R/29B SR · 46R/12B 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 DDT12, Big Eye Boy prints 28 Red (45.2%) and 34 Blue marks, Small Road prints 31 Red (51.7%) and 29 Blue marks, and Cockroach Pig prints 46 Red (79.3%) and 12 Blue marks.

At the DDT12 cut card after Hand #69, probing Hand #70 via getNextRoadPredictions() yields Banker → BEB BLUE / SR BLUE / CP RED and Player → BEB RED / SR RED / CP BLUE for DDT12.

Table Reality Check

Myth vs. Truth

MythThe second bead of each pair in DDT12 marks Blue because the 2-bead column is about to end.
TruthAt Row 2 in DDT12, 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.
