Step-by-Step Mark Proofs (Rule 1 & Rule 2)
DDT24 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.

DDT24 Small Road Entry #5

Column 5 has 2 beads. Column 3 has 1 bead. Different depth → blue (≠).

  1. Column 6 starts, so use Rule 1: compare Column 5 with Column 3, 2 columns further back.
  2. Column 5 has 2 beads. Column 3 has 1 bead. Different depth → blue (≠).

Common table reading watchout: Comparing the wrong columns. Compare Column 5, the one that just finished, with Column 3.

DDT24 Cockroach Pig Entry #4

Column 5 has 2 beads. Column 2 has 3 beads. Different depth → blue (≠).

  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 3 beads. Different depth → blue (≠).

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

DDT24 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.

DDT24 Big Eye Boy Rule Breakdown
65 Marks (32R / 33B · 49.2% Red across 28 Display Cols)

Rule 1: 30 marks · Rule 2 Case 1: 0 · Case 2: 0 · Case 3: 35.

DDT24 Small Road & Cockroach Pig Tally
SR: 31R/31B (50.0% Red) · CP: 43R/18B (70.5% 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.

DDT24 DERIVED-ROAD & CUT-CARD PROBE

DDT24 Lookback Split (32R/33B BEB · 31R/31B SR · 43R/18B 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 DDT24, Big Eye Boy prints 32 Red (49.2%) and 33 Blue marks, Small Road prints 31 Red (50.0%) and 31 Blue marks, and Cockroach Pig prints 43 Red (70.5%) and 18 Blue marks.

At the DDT24 cut card after Hand #75, probing Hand #76 via getNextRoadPredictions() yields Banker → BEB RED / SR BLUE / CP RED and Player → BEB BLUE / SR RED / CP BLUE for DDT24.

Table Reality Check

Myth vs. Truth

MythThe second bead of each pair in DDT24 marks Blue because the 2-bead column is about to end.
TruthAt Row 2 in DDT24, 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.
