STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 20U / 3-SHOE

Grand Martingale (2x+1) — 20-Unit Bankroll & 3-Shoe (216-Hand) Risk-of-Ruin Matrix

Sequential profile M127-0 evaluates Grand Martingale (2x+1) over a 3-shoe (216-hand) horizon with 20 units: bankroll-constrained escalation (1-3-7-15-31-63-127, 7 steps) interacts with the 60-unit limit to models a 94.80% ruin rate and a drawdown-weighted threshold of 1.67x. 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.

Grand Martingale 20u asymmetric progression-curve Across 216 Hands (M127)

Under configuration M127-1, deploying Grand Martingale with 20 base units over 216 resolved hands (3 shoes) audits a capital-bounded ledger: hitting the 60-unit house cap after 5 adverse steps drives a 94.80% stop-loss breach rate against a 16.68% chance of reaching the +6-unit target.

Sequential profile M127-2 tracks Grand Martingale (2x+1) over a 3-shoe (216-hand) horizon with 20 units: discrete-time escalation (1-3-7-15-31-63-127, 7 steps) interacts with the 60-unit limit to dissects a 94.80% ruin rate and a table-capped excursion of 1.67x.

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

Under configuration M127-3, deploying Grand Martingale with 20 base units over 216 resolved hands (3 shoes) measures a commission-adjusted excursion: hitting the 60-unit house cap after 5 adverse steps drives a 94.80% stop-loss breach rate against a 16.68% chance of reaching the +6-unit target.

Sequential profile M127-4 maps Grand Martingale (2x+1) over a 3-shoe (216-hand) horizon with 20 units: asymmetric escalation (1-3-7-15-31-63-127, 7 steps) interacts with the 60-unit limit to computes a 94.80% ruin rate and a commission-adjusted survival-window of 1.67x.

  • Cell M127 rule: lock the -10u stop on your 20u Grand Martingale stack across 216 hands.
  • Matrix M127 evaluates 6.42u ($321) in house hold over 361u of Grand Martingale action.
  • Scoreboard check M127: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (asymmetric progression-curve) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 20 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 361u in action, 6.42u 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 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.
