When Does Big Eye Boy Start? The Third-Hand Rule

Why does Big Eye Boy stay empty during the first column of a shoe and on the first cell of Column 2? Here are the two exact Big Road cells that trigger the very first Big Eye Boy mark.

Deal the first two or three hands of a fresh baccarat shoe and you will notice that the Bead Plate and Big Road light up right away while Big Eye Boy stays completely blank. Why doesn't Big Eye Boy start on Hand 1—and why do players call its opening trigger the “Second-Column / Third-Hand Rule”?

Because Big Eye Boy compares the active Big Road column against 1 column to the left, it cannot draw a mark during Column 1 (when there is no column to the left) or on the very first cell of Column 2 (when Column 2 has not finished, so you cannot yet compare finished column depths). Instead, Big Eye Boy always waits for the first hand after Column 2, Row 1—which lands on one of two exact Big Road cells.

The two possible starting cells for Big Eye Boy

ScenarioBig Road Trigger CellRule UsedHow First Color Is Decided
Case A: Column 2 wins a 2nd hand in a rowColumn 2, Row 2Rule 2 (Continuing Down)Check Column 1 at Rows 2 and 1: if Column 1 has depth ≥ 2 (both cells filled) → RED; if Column 1 stopped at depth 1 (one filled, one blank) → BLUE.
Case B: Column 2 stops at 1 hand and switches sidesColumn 3, Row 1Rule 1 (New Column)Compare Column 2's finished depth (1) with Column 1's depth: if Column 1 also had depth 1 → RED; if Column 1 had depth ≥ 2 → BLUE.

Case A — Starting at Column 2, Row 2 (Shoe: BBBPPB)

Suppose Banker opens the shoe with 3 wins (Column 1, depth 3), and then Player wins Hands 4 and 5:

BBBPPB
Case A (BBBPPB, 6 hands): Column 1 has 3 Banker wins and Column 2 has 2 Player wins. Big Eye Boy opens on Hand 5 (Column 2, Row 2) with a RED ring via Rule 2, followed by a BLUE ring on Hand 6 (Column 3, Row 1) via Rule 1.
  • Hands 1–3 (Banker streak in Column 1): No column sits to the left of Column 1, so Big Eye Boy records nothing.
  • Hand 4 (Player at Column 2, Row 1): Column 2 has just started. Why can't Rule 1 fire here? Because Rule 1 on Column c compares the finished depth of Column c−1 with Column c−2—and at Column 2, Column c−2 does not exist!
  • Hand 5 (Player at Column 2, Row 2 — First Mark!): Player wins a second time, advancing down Column 2 to Row 2. Now Rule 2 looks 1 column left at Column 1 (Rows 2 and 1). Because Column 1 has depth 3, both Row 1 and Row 2 in Column 1 are filled → Big Eye Boy draws its very first mark: a Red hollow ring.
  • Hand 6 (Banker at Column 3, Row 1 — Second Mark): Banker wins Hand 6, starting Column 3 at Row 1. Now Rule 1 compares Column 2's finished depth (2) with Column 1's depth (3) → different depths = Blue hollow ring.

Case B — Starting at Column 3, Row 1 (Shoe: BBBPBBPPBBPBBP)

What if Column 2 never reaches Row 2? In this 14-hand shoe, Banker wins Hands 1–3 (Column 1, depth 3), Player wins Hand 4 (Column 2, Row 1), and then Banker immediately wins Hand 5 to start Column 3:

BBBPBBPPBBPBBP
Case B (BBBPBBPPBBPBBP, 14 hands): Because Column 2 has only 1 Player win, Column 2 Row 2 never happens. Big Eye Boy opens on Hand 5 at Column 3, Row 1 with a BLUE ring via Rule 1.
  • Hand 4 (Column 2, Row 1): Still waiting for the hand after Column 2, Row 1.
  • Hand 5 (Column 3, Row 1 — First Mark!): Because Banker won Hand 5, Column 2 finished with a depth of 1. Big Eye Boy opens at Column 3, Row 1 under Rule 1, comparing Column 2's finished depth (1) with Column 1's depth (3) → different depths = Blue hollow ring.
  • Why it is sometimes called the “Third-Hand Rule”: In the fastest possible opening—B-P-B (or P-B-P) and B-P-P (or P-B-B)—Column 1 has depth 1, Hand 2 lands at Column 2 Row 1, and Hand 3 lands at either Column 2 Row 2 or Column 3 Row 1. Thus Hand 3 of the shoe is the earliest hand on which Big Eye Boy can ever produce its first mark (and Ties before that point simply delay the hand count without moving the Big Road cell).

Hand #14 · Why the newest marks are red or blue

  • Big Eye Boy: Column 7 has 2 beads. Column 6 has 1 bead. Different depth → blue (≠).
  • Small Road: Column 7 has 2 beads. Column 5 has 2 beads. Same depth → red (=).
  • Cockroach Pig: Column 7 has 2 beads. Column 4 has 2 beads. Same depth → red (=).

Frequently asked questions

On which Big Road cell does Big Eye Boy record its first mark?
Big Eye Boy records its first mark on the first hand dealt after Column 2, Row 1 of the Big Road: either at Column 2, Row 2 (if the second column wins a second hand in a row) or at Column 3, Row 1 (if the second column stops at depth 1 and switches sides).
Why can't Big Eye Boy start on Column 2, Row 1?
Because Row 1 of any Big Road column uses Rule 1, which compares the finished depth of the previous column (c minus 1) against the column before that (c minus 2). At Column 2, Column c minus 2 would be Column 0, which does not exist.
What is the earliest hand number in a shoe where Big Eye Boy can start?
Hand 3 of the shoe. If Hand 1 is Banker and Hand 2 is Player (reaching Column 2, Row 1 on Hand 2), then any non-tie Hand 3 lands at either Column 2, Row 2 (if Player wins again) or Column 3, Row 1 (if Banker wins) — which is why players call it the Third-Hand Rule.
Do Ties at the start of a shoe trigger Big Eye Boy?
No. Ties do not advance down a Big Road column or start a new column, so derived roads ignore Ties completely and wait for the first decided hand after Column 2, Row 1.
When do Small Road and Cockroach Pig record their first marks?
Small Road (lookback 2) starts one column later at Column 3, Row 2 or Column 4, Row 1. Cockroach Pig (lookback 3) starts one column after that at Column 4, Row 2 or Column 5, Row 1.
