How is this scored?
Each spin either nudges the line up or down: +1 for an Odd
number, −1 for an Even number. Green (0 or 00) doesn't move
the line at all, since it's neither odd nor even. The shaded
purple region above zero is "Odd territory," and the shaded
amber region below zero is "Even territory." In Unit Count
view the three moving averages smooth that same line over its
last 10, 20 and 50 spins, and each stays blank until enough
spins exist to fill its window. Click any legend entry to hide
or show that line.
🔼🔽 High / Low Unit Count

🟢 Zero (0) / Double Zero (00) Unit Count

How is this scored?
Only the two green pockets move this line: +1 for a 0, −1
for a 00. Every red or black number leaves it flat, so long
stretches of the chart are level by design — each pocket is
expected only about once every 38 spins. Above zero means 0
has landed more often than 00 this session; below zero means
the reverse. In Percentage view the line is 0's share of the
green spins only, where 50% is the even split. Click any
legend entry to hide or show that line.
🎯 0 / 00 Unit Count vs Expected
+1 each time that pocket hits; a miss leaves the line flat — against an expected average of 1 hit per 38 spins

How is this scored?
Each line counts how many times that pocket has landed: +1
on a hit, and no movement on a miss, so a line can only
climb or hold level. The gold line is the expected average —
one hit per 38 spins, since each pocket is 1 of 38. It
climbs slowly and smoothly while the tallies step up in
jumps, so expect them to cross back and forth rather than
track it closely. Click a legend entry to hide or show that
line.
📊 Column Unit Count vs Expected
+1 each time the column hits; a miss leaves the line flat. Switch to Pairs to count a hit on either of two columns

How is this scored?
Each line counts how many times that column has landed: +1
on a hit, and no movement at all on a miss, so a line can
only climb or hold level — it never falls. A green spin is
always a miss, since 0 and 00 sit in no column. In Pairs a
spin counts if either of the two columns lands. The gold
line is the expected average — where the count should sit by
that spin. A column covers 12 of the 38 pockets, so it gains
12 hits per 38 spins on average, and a pair covers 24. A
line above gold is running hot, one below it cold. Click a
legend entry to hide or show that line.

Expand a column to see its streak distribution — a 0 spin breaks any column streak, same as it would break a real column bet
🔁 Back-to-Back Occurrences by Dozen
1st Dozen (1–12) · 2nd Dozen (13–24) · 3rd Dozen (25–36) — a 0 spin breaks any dozen streak, same as it would break a real dozen bet
