STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 30U / 5-SHOE

Grand Martingale (2x+1) — 30-Unit Bankroll & 5-Shoe (360-Hand) Risk-of-Ruin Matrix

Across 360 eight-deck hands (5 shoes), finite-shoe simulation M130-0 for Grand Martingale (2x+1) on a 30-unit bankroll computes a 94.80% risk-of-ruin figure, documents 40 ceiling-collision events against the 80-unit cap and a 0.50% mid-corridor finish rate. 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.

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.

MATRIX CELL M130 · STOP-LOSS & STOP-WIN GEOMETRY

Grand Martingale 30u multi-coup distribution Across 360 Hands (M130)

Cell M130-1 inspects the session-bounded capital-runway of a 30-unit Grand Martingale plan over 360 hands: because each hand remains independent at 1.058% Banker edge, scaling stakes toward the 80-unit ceiling elevates total turnover to 724u and sets ruin at 94.80%.

Across 360 eight-deck hands (5 shoes), variance-scaled simulation M130-2 for Grand Martingale (2x+1) on a 30-unit bankroll verifies a 94.80% risk-of-ruin figure, profiles 40 ceiling-collision events against the 80-unit cap and a 0.50% mid-corridor finish rate.

80u Ceiling Collisions & Grand Martingale Turnover (5 Shoes)

Cell M130-3 tabulates the step-indexed absorption-curve of a 30-unit Grand Martingale plan over 360 hands: because each hand remains independent at 1.058% Banker edge, scaling stakes toward the 80-unit ceiling elevates total turnover to 724u and sets ruin at 94.80%.

Across 360 eight-deck hands (5 shoes), eight-deck simulation M130-4 for Grand Martingale (2x+1) on a 30-unit bankroll quantifies a 94.80% risk-of-ruin figure, benchmarks 40 ceiling-collision events against the 80-unit cap and a 0.50% mid-corridor finish rate.

  • Cell M130 rule: lock the -15u stop on your 30u Grand Martingale stack across 360 hands.
  • Matrix M130 charts 12.87u ($644) in house hold over 724u of Grand Martingale action.
  • Scoreboard check M130: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (multi-coup distribution) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 30 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 724u in action, 12.87u in expected loss, and a 94.80% 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.
