How to Read Bead Plates and Derived Road Displays: A Sin88 Roadmap Guide

The bead plate is the master record of every dealt hand, and the four derived road displays — Big Road, Big Eye Boy, Small Road, and Cockroach Road — are compact visual summaries built from that master record. If you want to read them correctly, learn the construction rules first, then practice on a fixed hand sequence, and only then use them at a live table. This guide walks through each layer in that exact order.

What You Need Before You Touch a Roadmap

Roadmap displays assume you already know the three possible outcomes in baccarat: Player, Banker, and Tie. You also need to know which colors the table uses for each outcome. Most platforms mark Player in blue, Banker in red, and Tie in green, but this is not a universal standard. Always confirm the color key before interpreting anything.

Before you rely on any roadmap display — whether on a site such as sin88 or at a physical table — confirm the color key first. It takes five seconds and prevents the most common misreading in the entire game.

You should also understand one fundamental limitation: roadmaps are historical records. They show where the shoe has been, not where it is going. Treat them as descriptive tools for spotting structure, not as prediction machines.

Bead Plate: The Master Record of Every Hand

The bead plate is a grid that logs each hand in the order it was dealt. The standard layout uses six rows per column. The first hand sits in the top-left cell, the second hand goes directly below it, and the grid fills downward to the sixth row. The seventh hand starts the next column to the right. Continue this pattern across the plate and you get a chronological, left-to-right history of the shoe.

Ties follow a special rule. When a tie occurs, it is marked in the current cell — usually with a green line, circle, or letter — and the next non-tie result is recorded in the same column. In other words, a tie does not advance the plate to the next row and does not create a new column. This rule matters later when you compare the bead plate with the derived roads, because different platforms handle ties slightly differently on the derived roads themselves.

Why start with the bead plate? Because every derived road is mathematically constructed from the same stream of results. If you understand how the bead plate fills, you will find it much easier to see why a derived road redraws the way it does.

The Four Derived Roads and Their Construction Rules

Derived roads are not independent records. Each one is a transformation of the results already shown in the Big Road, which is itself the first derived display most players learn. The four roads form a family with progressively longer memory: Big Road shows raw streaks, Big Eye Boy looks one column back, Small Road looks two columns back, and Cockroach Road looks three columns back.

Big Road

The Big Road is built from simple rules. Consecutive wins for the same side stack vertically in the same column. When the winning side changes, a new column starts to the right. This creates a visual pattern where tall columns represent streaks and short columns represent zigzag play.

For example, five Banker wins in a row would appear as a single column with five stacked circles. A result of Player only appears in the Big Road by ending the Banker streak and starting a new column. Ties are noted but generally do not break a column; they are recorded on the current circle and the next win/loss decision continues in the same row structure. Some platforms handle ties differently, so the same caveat about checking the key applies.

Big Eye Boy

Big Eye Boy is the first derived road. It is read from the Big Road and does not begin until the second column of the Big Road exists. For each entry in the Big Road, the rule is:

• If the entry is in the first row of its column, compare it with the entry in the previous column at the same first row. Same result = red, different = blue.
• If the entry is below the first row, compare it with the entry directly above it in the same column. Same result = red, different = blue.

Big Eye Boy answers an important question: does the Big Road look organized? When it prints long runs of the same color, the underlying Big Road is following a predictable pattern. When it alternates frequently, the Big Road is choppy.

Small Road

Small Road works exactly like Big Eye Boy, but with one key difference: instead of comparing against the previous column, it compares against the column two positions back. It also begins later, starting from the third column of the Big Road. For first-row entries, the comparison target is the cell in the column two back at the same row. For lower rows, the comparison target is still the cell directly above in the current column.

Because Small Road extends further into the history, it is less sensitive to the immediate last hand. Players use it to check whether the pattern that Big Eye Boy shows is holding over a longer span.

Cockroach Road

Cockroach Road continues the same logic one more step back. It compares against the column three positions back and begins from the fourth column of the Big Road. It is the least reactive of the four derived roads and tends to stay stable for longer stretches. A streak in Cockroach Road suggests that the same structural pattern has been repeating for a substantial number of hands.

How to Read a Roadmap in Eight Steps

Now that the construction rules are clear, here is a repeatable reading routine. It works for any baccarat table that displays bead plates and derived roads.

1. Confirm the color key. Identify which color represents Player, Banker, and Tie before reading anything else.
2. Identify the display type. Check the label or the position of the grid. The bead plate is the grid with six rows per column. The derived roads sit to the right or below it on most layouts.
3. Locate the newest hand. On the bead plate, the newest recorded result is the most recently filled cell. On the derived roads, it is the rightmost entry. Reading from the wrong end is the quickest way to draw the wrong conclusion.
4. Read columns as streaks. A tall column on the Big Road means repeated consecutive wins for one side. The longer the column, the longer the streak.
5. Read the space between columns as zigzag. Many short columns next to each other mean the game is alternating sides rapidly.
6. Compare Big Eye Boy and Small Road. If Big Eye Boy is steady but Small Road is mixed, the pattern is short-lived. If both are steady in the same direction, the structural pattern is more established.
7. Note the amount of data. A road with six entries is almost meaningless. A road with fifty entries shows a real structure worth analyzing.
8. Convert the read into a bankroll decision. Roadmaps help you choose when to be conservative or when to step back. They never tell you to raise your stake.

A 12-Hand Example You Can Verify

To show how the rules work together, take this 12-hand sequence: Banker, Banker, Player, Banker, Player, Banker, Banker, Banker, Player, Player, Banker, Player.

Reading this onto a Big Road gives the following structure: Column 1 holds two Banker results, column 2 holds one Player result, column 3 holds one Banker result, column 4 holds one Player result, column 5 holds three Banker results, column 6 holds two Player results, column 7 holds one Banker result, and column 8 holds one Player result.

From that Big Road, the derived roads produce the following entries, reading left to right in chronological order:

This example demonstrates why you cannot read derived roads without the Big Road beside them. The all-red Small Road looks like a strong trend at first glance, but it is simply the mathematical consequence of a short, repetitive sequence. If you look at the Big Road, you can see exactly which columns caused those reds. That is the correct way to interpret a roadmap: you verify the derivation instead of trusting the color at face value.

Common Mistakes That Skew Roadmap Reading

The most frequent errors are structural, not mathematical. Here is what to watch for:

• Treating a tie as a column break. On most tables, a tie is noted in the current cell and does not advance the column. If you treat it as a new column, every subsequent derived road will be offset.
• Ignoring the lag on derived roads. Big Eye Boy has fewer entries than the Big Road because it starts at the second column. Small Road and Cockroach Road start even later. A player who compares lengths without accounting for this lag will misjudge the history.
• Confusing the comparison offsets. Big Eye Boy references one column back, Small Road references two columns back, and Cockroach Road references three columns back. Swapping them produces a completely different reading.
• Believing a balanced or focused road is a prediction. The fact that the last twelve hands formed a neat pattern does not increase the probability of the next hand following it. Each hand in baccarat is an independent event.
• Reading with too little data. Do not draw conclusions from a road that shows only a handful of hands. The display needs a meaningful sample before the structure it reveals is worth acting on.

The Checklist to Take to the Table

Before you sit down with a bead plate and derived roads in front of you, run through this final checklist so that your reading is consistent every time.

• I know which color represents Player, Banker, and Tie on this specific table.
• I have identified whether I am looking at the bead plate or a derived road.
• I know where the newest hand is recorded on the display I am using.
• I am reading columns as streaks and row changes as transitions.
• I remember which offset each derived road uses: one back for Big Eye Boy, two back for Small Road, three back for Cockroach Road.
• I have compared my derived-road read against the Big Road to confirm the structure exists.
• I have set a loss limit before the session, and I will not raise it because a roadmap looks confident.

Any roadmap display is useful only when the person reading it understands what it can and cannot do. It can organize the past into visible structure. It cannot predict the next hand, and no pattern, however consistent, changes the fundamental risk of the game. Keep the reading routine simple: verify the key, check the latest hand, read the structure, and let your bankroll rules do the decision-making.
