Grand Martingale (1-3-7-15-31) — 500-Hand High-Limit Marathon (200u Bankroll) Survival & Ruin Proof

[GMRS500] Doubles the prior wager plus 1 extra unit after every loss (1, 3, 7, 15, 31) and resets to 1u on a win. Across 500-Hand High-Limit Marathon (200u Bankroll) (Six-shoe salon marathon exposing long-run house-edge drift against a 200-unit reserve), staking Grand Martingale on Player (1.2351% house edge) generates 2210.0 units of cumulative action, an expected mathematical cost of −27.30 units, ±94.01 units of standard deviation, and a 63.4% session survival rate (36.6% bankroll ruin risk).

Step-by-Step Mark Proofs (Rule 1 & Rule 2)
Big Eye Boy Mark #2

This bead is at Row 3. Column 1 has a bead at Row 3 too → red (=).

  1. Column 2 goes down to Row 3, so use Rule 2: look 1 column back, at Column 1.
  2. Column 1 has a bead at Row 3 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.

Small Road Mark #2

This bead is at Row 3. Column 1 has a bead at Row 3 too → red (=).

  1. Column 3 goes down to Row 3, so use Rule 2: look 2 columns back, at Column 1.
  2. Column 1 has a bead at Row 3 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.

Cockroach Pig Mark #2

This bead is at Row 3. Column 1 has a bead at Row 3 too → red (=).

  1. Column 4 goes down to Row 3, so use Rule 2: look 3 columns back, at Column 1.
  2. Column 1 has a bead at Row 3 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.

GMRS500 STOCHASTIC HORIZON

Grand Martingale (GMRS500) Over 500 Hands With a 200-Unit Bankroll

[GMRS500-MECHANICS] Staking protocol GMRS500 applies Grand Martingale (1-3-7-15-31) (1-3-7-15-31-63) on Player across 500 hands with a 200-unit stop-loss. Doubles the prior wager plus 1 extra unit after every loss (1, 3, 7, 15, 31) and resets to 1u on a win. Six-shoe salon marathon exposing long-run house-edge drift against a 200-unit reserve.

[GMRS500-EXPECTATION] By linearity of expectation, GMRS500 cannot alter the 8-deck 1.2351% Player house edge: multiplying 2210.0u cumulative action by −1.2351% locks in −27.30u expected drift with ±94.01u standard deviation. Accelerates cumulative bankroll commitment to 57 units by step 5, exhausting medium bankrolls two steps faster than standard Martingale. Remember that baccarat is an 18+ / 21+ game of chance; review /legal/responsible-gambling before setting session limits.

  • GMRS500 step sequence: 1-3-7-15-31-63 (4.42u mean bet size across 500 hands).
  • GMRS500 bankroll boundary: 200u starting stack faces 36.6% ruin risk and 63.4% survival probability.
  • GMRS500 road independence: Big Eye Boy and Small Road patterns on BBBPPPBB never change the −27.30u expected house hold.
Table Reality Check

Myth vs. Truth

MythRunning Grand Martingale over 500 hands with 200 units changes the mathematical expectation of the shoe.
TruthEvery hand in GMRS500 faces the same 1.2351% Player house edge; scaling bet sizes to 2210.0u total action scales expected cost to −27.30u while reshaping variance (±94.01u SD).
