STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 150U / 10-SHOE

Grand Martingale (2x+1) — 150-Unit Bankroll & 10-Shoe (720-Hand) Risk-of-Ruin Matrix

Within non-stationary horizon M143-0, a 150-unit treasury backing Grand Martingale (2x+1) for 720 hands (10 shoes) faces a 100-unit bet cap that measures 94.80% ruin exposure, 19.74% target attainment at +38u, and 0.50% 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.

Table Reality Check

Myth vs. Truth

MythBringing 150 units to a 10-shoe session lets Grand Martingale (2x+1) overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 720 hands, Grand Martingale generates 4342u in action, 77.17u 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 720-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.
