Every derived road on a Macau or Las Vegas baccarat scoreboard—Big Eye Boy (lookback 1, hollow circles), Small Road (lookback 2, solid circles), and Cockroach Pig (lookback 3, slashes)—follows the exact same two rules: Rule 1 when starting a new Big Road column, and the three-case Rule 2 when continuing down a column. On derived roads, Red (=) always means the Big Road pattern is repeating and Blue (≠) always means the pattern broke.
Opening `BPPP` sequence demonstrating Rule 2 Case 2 (Blue ≠ at Row 2) and Rule 2 Case 3 (Red = at Row 3) on Big Eye Boy.
This bead is at Row 2. Column 1 stopped at Row 1, one row above → blue (≠).
Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.
This bead is at Row 3. Column 1 stopped at Row 1, more than one row above → red (=).
Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.
Column 2 has 3 beads. Column 1 has 1 bead. Different depth → blue (≠).
Common table reading watchout: Comparing the wrong columns. Compare Column 2, the one that just finished, with Column 1.
Hollow circles (lookback 1), solid circles (lookback 2), and diagonal slashes (lookback 3).
1-based Big Road coordinates where each derived road begins recording marks.
Same depth = Red (=); different depth = Blue (≠).
Case 1 (bead at Row R) = Red (=); Case 2 (stopped at Row R-1) = Blue (≠); Case 3 (stopped at Row <= R-2) = Red (=).
Because Rule 1 tests depth === refDepth and Rule 2 tests depth !== refDepth against the same reference column.
Derived roads never record whether Banker or Player won a hand. Instead, they answer one structural question: is the Big Road repeating the column pattern it established N columns ago (Red =), or breaking from it (Blue ≠)?
Every walkthrough in this hub isolates one exact combination of road (Big Eye Boy, Small Road, or Cockroach Pig) and rule case (Starting Conditions, Rule 1 Red, Rule 1 Blue, Rule 2 Case 1 Red, Rule 2 Case 2 Blue, Rule 2 Case 3 Red, and the Prediction Table), complete with 1-based Big Road highlight coordinates and verbatim describeMark() steps.

Mistake #1 occurs on Rule 1 (starting a new column at Row 1): learners accidentally compare the brand-new 1-bead column (`Column C`) against the previous column. Because Column C has only just started and its final depth is unknown, Rule 1 always compares the column that JUST FINISHED (`Column C - 1`) with the column N positions further back (`Column C - 1 - N`).
Mistake #2 occurs on Rule 2 (continuing down to Row R): learners memorize the false shortcut 'if the reference column has no bead at Row R, mark Blue.' As `BPPP` proves, no bead at Row R is Blue (≠) ONLY when the reference column stopped at Row R - 1 (one row above). When the reference column stopped two or more rows above, Rule 2 Case 3 marks Red (=).
