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

This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).

  1. Column 2 goes down to Row 3, so use Rule 2: look 1 column back, at Column 1.
  2. Column 1 stopped at Row 2, 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.

Small Road Mark #2

This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).

  1. Column 3 goes down to Row 3, so use Rule 2: look 2 columns back, at Column 1.
  2. Column 1 stopped at Row 2, 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.

Cockroach Pig Mark #2

Column 4 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

  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 2 beads. Same depth → red (=).

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

How Six-Pip Card Depletion at 75% Depth Impacts 8D (4% Vig)

Audit DEP421 evaluates a 8-deck (416-card) shoe at 75% penetration where 28 of 32 Six-Pip Card cards have exited, leaving 4 Rank-6 cards inside the 104-card stub with Banker EV at -0.6096% under 4%.

Under the fixed third-card tableau for DEP421, banker 6 only draws (dep421) when player pulls a third-card (8d-75%) 6 or 7; depleting 6s (dep421·8d-75%) directly alters both banker 6 draws and super 6 settlement frequency. With 4 Rank-6 cards inside 104 remaining 8D cards (75% dealt), single-card slope (-1.13 bps) keeps Banker house edge at 0.6096% and Player at 1.2246%.

Table Reality Check

Myth vs. Truth

MythWhen 28 Six-Pip Card cards leave a 8D shoe by 75% depth (DEP421), Big Eye Boy red or blue marks show whether Banker or Player will win next.
TruthDerived-road red and blue marks only compare Big Road column lengths and never track Rank-6 stub counts (4/32 in 104 cards); Banker carries a -0.6096% expectation under 4%.
