STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 150U / 3-SHOE

Grand Martingale (2x+1) — 150-Unit Bankroll & 3-Shoe (216-Hand) Risk-of-Ruin Matrix

When a 150-unit stack enters a 3-shoe (216-hand) session using Grand Martingale (2x+1), house-edge-anchored model M142-0 benchmarks 1302u in cumulative action and a 38.84% barrier-absorption probability before the 60-unit table maximum truncates the eight-deck drawdown-slope. 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.

Testing Grand Martingale (1-3-7-15-31-63-127) at 150 units across 216 coups in cell M142-1 models a 38.84% chance of striking the -75-unit stop-loss, while the 60-unit pit ceiling and 1.058% Banker edge impose 23.14u ($1157) in expected erosion.

When a 150-unit stack enters a 3-shoe (216-hand) session using Grand Martingale (2x+1), sequential model M142-2 computes 1302u in cumulative action and a 38.84% barrier-absorption probability before the 60-unit table maximum truncates the finite-shoe capital-runway.

60u Ceiling Collisions & Grand Martingale Turnover (3 Shoes)

Testing Grand Martingale (1-3-7-15-31-63-127) at 150 units across 216 coups in cell M142-3 inspects a 38.84% chance of striking the -75-unit stop-loss, while the 60-unit pit ceiling and 1.058% Banker edge impose 23.14u ($1157) in expected erosion.

When a 150-unit stack enters a 3-shoe (216-hand) session using Grand Martingale (2x+1), multi-coup model M142-4 verifies 1302u in cumulative action and a 38.84% barrier-absorption probability before the 60-unit table maximum truncates the stochastic envelope.

  • Cell M142 rule: lock the -75u stop on your 150u Grand Martingale stack across 216 hands.
  • Matrix M142 profiles 23.14u ($1157) in house hold over 1302u of Grand Martingale action.
  • Scoreboard check M142: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (non-stationary stake-velocity) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 150 units to a 3-shoe session lets Grand Martingale (2x+1) overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 216 hands, Grand Martingale generates 1302u in action, 23.14u in expected loss, and a 38.84% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell Grand Martingale bettors whether Banker (red) or Player (blue) is due during a 216-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.
