STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 500U / 5-SHOE

Grand Martingale (2x+1) — 500-Unit Bankroll & 5-Shoe (360-Hand) Risk-of-Ruin Matrix

Within drawdown-weighted horizon M150-0, a 500-unit treasury backing Grand Martingale (2x+1) for 360 hands (5 shoes) faces a 80-unit bet cap that dissects 18.31% ruin exposure, 42.18% target attainment at +125u, and 39.51% time-limit expiration. Every 8-deck hand remains statistically independent (45.86% Banker, 44.62% Player, 9.52% Tie), meaning progression sizing reshapes session variance without altering the house edge.

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

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

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

Common table reading watchout: Comparing the wrong columns. Compare Column 2, the one that just finished, with Column 1.

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

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

  1. Column 4 goes down to Row 3, so use Rule 2: look 3 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.

Table Reality Check

Myth vs. Truth

MythBringing 500 units to a 5-shoe session lets Grand Martingale (2x+1) overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 360 hands, Grand Martingale generates 2207u in action, 39.22u in expected loss, and a 18.31% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell Grand Martingale bettors whether Banker (red) or Player (blue) is due during a 360-hand run.
TruthOn Big Eye Boy, Small Road, and Cockroach Pig, red indicates repeating column structure and blue indicates breaking structure; neither color represents Banker or Player.
