Cockroach Pig is a baccarat derived road displayed with red and blue diagonal marks. It is also called Cockroach Road on many scoreboards and in English-language explanations.
The unusual name hides a precise function: it compares the shape of the Big Road with earlier columns. It does not record a new Banker or Player result, and its colors do not mean Banker and Player.
Cockroach Pig is the third of the common derived roads:
| Derived road | Typical mark | Depth of comparison |
|---|---|---|
| Big Eye Boy | Red or blue circles | Nearest structural comparison |
| Small Road | Red or blue solid dots | One level deeper |
| Cockroach Pig | Red or blue diagonal slashes | Deepest of the standard three |
Different displays may translate or label these roads differently. “Cockroach Pig,” “Cockroach Road,” and sometimes “Small Cockroach Road” can refer to the same third derived chart. The symbol and calculation are more reliable identifiers than the English label.
It is built from the Big Road, not from the shoe directly
The Big Road groups consecutive Banker and Player wins into columns. Ties normally annotate an existing result rather than creating a fresh Banker-or-Player cell.
Cockroach Pig does not inspect the card ranks, the shoe order or the raw probability of the next hand. It receives a new mark only after the Big Road has enough column structure for the required comparison.
That distinction prevents three common errors:
- a red slash is not a Banker prediction;
- a blue slash is not a Player prediction;
- a long run of one color does not change the drawing rules or remove the house edge.
The chart is a transformation of past outcomes. Once the Big Road is known, the Cockroach Pig marks are determined by the chosen roadmap algorithm.
What the red and blue slashes mean
In the usual derived-road convention:
- red indicates that the compared Big Road structure is behaving consistently under the road’s rule;
- blue indicates that the compared structure differs under that rule.
“Consistent” does not mean mathematically predictable. It means only that two locations in an already recorded grid satisfy the same structural test.
A display can therefore show a red Cockroach Pig slash after a Player win or after a Banker win. The direct winner determines where the Big Road moves; the resulting Big Road position determines the derived color.
The standard lookback logic
Cockroach Pig looks farther back than Big Eye Boy and Small Road. A practical way to understand the standard method is to separate two cases.
When the Big Road starts a new column
A new column begins when the winning side changes, ignoring Tie annotations. The Cockroach Pig comparison tests the depth of two earlier Big Road columns separated by the road’s three-column lookback. If the compared depths match, the derived mark is red; if they differ, it is blue.
When the Big Road continues down the same column
A repeated Banker or Player result extends the current column. The Cockroach Pig test looks three columns to the left at the corresponding row position and compares that cell with the one immediately above it. Matching occupancy produces one color; different occupancy produces the other.
The exact starting cell is easy to misstate because interfaces number columns differently and road diagrams describe “columns back” from different reference points. The safest practical rule is this: Cockroach Pig cannot begin until the Big Road contains enough history for a three-column structural comparison. A trusted display calculates it automatically.
For readers implementing the chart in software, the algorithm should be tested against a known roadmap example rather than coded from color intuition. An off-by-one column error can create a convincing but entirely different road.
A compact example
Imagine these Big Road column depths, read from left to right:
3, 1, 3, 2, …
When a later result creates a new column, the Cockroach Pig rule compares two earlier columns at its specified separation. If the relevant depths are both 3, the mark is red. If they are 3 and 2, the mark is blue.
For that new-column case, the comparison can be written compactly as:
Derived color = red when the two required column depths are equal; blue when they are unequal.
The two depths are the columns selected by the road’s standard lookback rule. This notation describes the display calculation only; it does not estimate the next hand’s probability.
Now imagine the current Big Road column continues from row 2 to row 3. The algorithm checks the corresponding location three columns to the left. If both the target cell and the cell above share the required occupied-or-empty relationship, the mark is red; otherwise it is blue.
The example explains the kind of test, not a betting signal. The mark reports whether past grid shapes match.
Why the road uses slashes
The diagonal slash distinguishes Cockroach Pig from the circular Big Eye Boy and solid-dot Small Road when several charts share one display. Red and blue are already used across baccarat scoreboards, so shape is needed to prevent one road from being mistaken for another.
Typical electronic displays show the derived roads beneath or beside the Big Road. On a manual scorecard, players may draw:
- open circles for Big Eye Boy;
- filled circles or dots for Small Road;
- short diagonal strokes for Cockroach Pig.
A casino may use different colors or icons, especially in digital products. The legend on the table display controls.
The term is real, but the prediction claim is not
The Wizard of Odds explanation of baccarat scoreboards documents Cockroach Pig as the third derived chart and describes its three-column lookback from the Big Road. That supports the term’s use; it does not establish a forecasting advantage.
Baccarat outcomes are generated by the remaining card composition and the fixed third-card rules. A road is not part of that causal process. It neither rearranges the shoe nor tells the dealer which card to draw.
Suppose the last twelve Cockroach Pig marks are red. That statement tells you that the Big Road repeatedly met the red structural condition. It does not supply the probability that the next coup will be Banker, Player or Tie. The next hand still resolves under the same approved rules and payout structure.
This is the same boundary explained in Why Baccarat Roads Cannot Predict the Next Hand and Roadmap Prediction Myth.
A useful verification role
Although it has no predictive power, Cockroach Pig can still be useful as a recordkeeping check.
If a player’s handwritten road disagrees with the table display, the difference can reveal:
- a missed Banker or Player result;
- a Tie incorrectly entered as a new Big Road cell;
- the wrong derived-road starting point;
- a mistaken column-depth comparison;
- a display that uses a different symbol convention.
The proper response is to trace the Big Road first. Trying to “correct” Cockroach Pig without confirming its source grid usually compounds the error.
For casino operations, the derived road is secondary to the official game record. A dispute about a wager is settled from cards, bets, approved rules, dealer calls and surveillance evidence—not from whether a roadmap looked red or blue.
Cockroach Pig versus Cockroach Road
The site has a separate Cockroach Road entry because readers search both names. They should not be treated as two independent systems unless a particular manufacturer explicitly defines them that way.
Use this identification test:
| Question | If the answer is yes |
|---|---|
| Does the chart use red and blue diagonal strokes? | It is probably the third derived road |
| Is it calculated from Big Road structure? | It is a derived chart, not a direct result board |
| Does it look three columns back under the standard method? | Cockroach Pig/Cockroach Road is the likely label |
| Does it claim to forecast Banker or Player? | The claim goes beyond what the chart records |
The glossary term is therefore best understood as a name for a deterministic display transformation. Its marks may be interesting, culturally familiar and useful for checking a scorecard. They are not evidence that the shoe has developed memory.
