Straight versus split
One square and a shared edge represent different covered sets.
A single-zero reference
- Wheel

- Inside
- Specific numbers or adjacent groups on the layout.
- Outside
- Larger groups such as red/black or dozens.
- Closing point
- Selections close at the table’s announced cutoff.
One wheel, several kinds of selection
The wheel’s pocket sequence is not the same as the order of numbers printed on the table. A split concerns adjacent table squares, not simply neighbouring wheel pockets. This distinction prevents a common mistake when interpreting grouped selections.
A live presentation adds the dealer’s announcement and a visible result marker. The valid result and round status matter more than a frozen video image. If the picture stops, do not infer the final outcome from where the ball appeared to be.
Reading a standard roulette round
This page describes a conventional single-zero format. Double-zero games have an additional pocket and should not be read as identical.
Some tables add rules such as la partage. Their presence cannot be assumed from the word European alone; read the actual table rules before applying them.
Select the covered set
A straight covers one number; a split covers two adjoining layout numbers. The marked position defines the selection.
Observe the cutoff
After the closing announcement, selections cannot be treated as newly accepted merely because chips remain visible.
Match the pocket
Use the announced winning pocket to check all selected sets. One number can belong to several groups.
Apply zero rules
Zero is neither red nor black and is excluded from ordinary odd/even and high/low groups. Special rules must be explicit.
Check a completed round in order
A result check uses the final round information and the exact covered set.
Confirm the round
Match the displayed round identifier or sequence.
Read the result
Use the final number, not an intermediate ball position.
Map the selection
Check whether the result lies within the selected group.
Read exceptions
Apply any explicit zero or void-round rule separately.
The layout vocabulary

Questions about single-zero roulette
Does red become due after black?
No. Earlier independent spins do not force the next colour.
Are wheel neighbours table neighbours?
Not necessarily. Read the layout for split and corner coverage.
Does every European table use la partage?
No. It must be stated in that table’s rules.
Does a picture prove a live table?
No. This page’s casino imagery illustrates the format and is not a live game feed.
