2.5% Banker Commission Proof & The 2.6932% Break-Even Threshold

Winning Banker bets pay 0.975 to 1 (2.5% commission), crossing below the 2.6932% zero-house-edge boundary. Never offered as an unconditioned walk-up game without offsetting rules because 2.5% vig is below the combinatorial break-even tax. Setting 0.458597 × (1 − c) − 0.446247 = 0 solves to c = 0.026932 (2.6932% exact break-even commission in an 8-deck shoe). At c = 2.5%, expected return is 0.458597 × 0.975 − 0.446247 = +0.000886 (+0.0886% in favor of the Banker ticket holder).

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

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

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

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 2 stopped exactly one row above this bead.

Small Road Mark #2

Column 3 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

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

Common table reading watchout: Comparing the wrong columns. Compare Column 3, the one that just finished, with Column 1.

Cockroach Pig Mark #2

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

  1. Column 5 goes down to Row 2, so use Rule 2: look 3 columns back, at Column 2.
  2. Column 2 stopped at Row 1, one row above → blue (≠).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 2 stopped exactly one row above this bead.

COMM25 COMBINATORIAL AUDIT

2.5% Banker Commission Proof & The 2.6932% Break-Even Threshold — Exact 8-Deck Accounting

[COMM25-MECHANISM] Winning Banker bets pay 0.975 to 1 (2.5% commission), crossing below the 2.6932% zero-house-edge boundary. Never offered as an unconditioned walk-up game without offsetting rules because 2.5% vig is below the combinatorial break-even tax. Across Theoretical actuarial boundary and promotional loss-cap coupon audits, pit supervisors enforce this exact settlement table on every 416-card shoe.

[COMM25-PROOF] Setting 0.458597 × (1 − c) − 0.446247 = 0 solves to c = 0.026932 (2.6932% exact break-even commission in an 8-deck shoe). At c = 2.5%, expected return is 0.458597 × 0.975 − 0.446247 = +0.000886 (+0.0886% in favor of the Banker ticket holder). Because each six-card deal is governed by the fixed third-card tableau, scoreboard trends on Big Eye Boy, Small Road, and Cockroach Pig cannot shift the -0.0886% (Player Adv.) Banker expectation.

Table Reality Check

Myth vs. Truth

MythCasinos could easily cut Banker commission in half to 2.5% and still hold a comfortable house edge.
TruthBecause raw Banker wins (45.8597%) exceed raw Player wins (44.6247%) by only 1.2351%, any commission below 2.6932% hands the mathematical edge to the bettor.
