1-2-3-5 Four-Step Ladder — 20-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix

Case M201-0 quantifies the multi-coup 1-2-3-5 Four-Step Ladder (1-2-3-5) across a 20-unit bankroll and a 72-hand (1-shoe) window, where a 40-unit table ceiling and 10-unit stop-loss produce a 34.27% ruin rate while maps an average stake drawdown-slope of 1.10x and 0.93u ($23) in theoretical house-edge toll. 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.

Reference 8-deck shoe for Matrix Cell M201 (1-2-3-5 Four-Step Ladder, 20u bankroll, 72 hands). Big Road and Bead Plate show Banker (red) and Player (blue); derived roads record structural symmetry.

Big Road B is Banker, P is Player Roads under it Red (=): repeating Blue (≠): breaking
Step-by-Step Mark Proofs (Rule 1 & Rule 2)
Big Eye Boy Mark #2

This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).

  1. Column 2 goes down to Row 3, so use Rule 2: look 1 column back, at Column 1.
  2. Column 1 stopped at Row 2, one row above → blue (≠).

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 stopped at Row 2, one row above → blue (≠).

  1. Column 3 goes down to Row 3, so use Rule 2: look 2 columns back, at Column 1.
  2. Column 1 stopped at Row 2, one row above → blue (≠).

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

Column 4 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

  1. Column 5 starts, so use Rule 1: compare Column 4 with Column 1, 3 columns further back.
  2. Column 4 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 4, the one that just finished, with Column 1.

  • Cell M201 rule: lock the -10u stop on your 20u 1-2-3-5 stack across 72 hands.
  • Matrix M201 inspects 0.93u ($23) in house hold over 79u of 1-2-3-5 action.
  • Scoreboard check M201: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (combinatorial envelope) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 20 units to a 1-shoe session lets 1-2-3-5 Four-Step Ladder overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 72 hands, 1-2-3-5 generates 79u in action, 0.93u in expected loss, and a 34.27% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell 1-2-3-5 bettors whether Banker (red) or Player (blue) is due during a 72-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.
