STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 200U / 2-SHOE

Grand Martingale (2x+1) — 200-Unit Bankroll & 2-Shoe (144-Hand) Risk-of-Ruin Matrix

Across 144 eight-deck hands (2 shoes), asymmetric simulation M144-0 for Grand Martingale (2x+1) on a 200-unit bankroll evaluates a 18.68% risk-of-ruin figure, models 26 ceiling-collision events against the 50-unit cap and a 39.66% 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.

MATRIX CELL M144 · STOP-LOSS & STOP-WIN GEOMETRY

Grand Martingale 200u combinatorial drawdown-slope Across 144 Hands (M144)

Cell M144-1 audits the combinatorial trajectory of a 200-unit Grand Martingale plan over 144 hands: because each hand remains independent at 1.058% Banker edge, scaling stakes toward the 50-unit ceiling elevates total turnover to 883u and sets ruin at 18.68%.

Across 144 eight-deck hands (2 shoes), non-stationary simulation M144-2 for Grand Martingale (2x+1) on a 200-unit bankroll tracks a 18.68% risk-of-ruin figure, dissects 26 ceiling-collision events against the 50-unit cap and a 39.66% mid-corridor finish rate.

50u Ceiling Collisions & Grand Martingale Turnover (2 Shoes)

Cell M144-3 measures the table-capped cycle-span of a 200-unit Grand Martingale plan over 144 hands: because each hand remains independent at 1.058% Banker edge, scaling stakes toward the 50-unit ceiling elevates total turnover to 883u and sets ruin at 18.68%.

Across 144 eight-deck hands (2 shoes), house-edge-anchored simulation M144-4 for Grand Martingale (2x+1) on a 200-unit bankroll maps a 18.68% risk-of-ruin figure, computes 26 ceiling-collision events against the 50-unit cap and a 39.66% mid-corridor finish rate.

  • Cell M144 rule: lock the -100u stop on your 200u Grand Martingale stack across 144 hands.
  • Matrix M144 evaluates 15.69u ($392) in house hold over 883u of Grand Martingale action.
  • Scoreboard check M144: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (combinatorial drawdown-slope) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 200 units to a 2-shoe session lets Grand Martingale (2x+1) overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 144 hands, Grand Martingale generates 883u in action, 15.69u in expected loss, and a 18.68% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell Grand Martingale bettors whether Banker (red) or Player (blue) is due during a 144-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.
