Pockets
Thirty-seven numbers including one zero.
123mkv — European roulette
European roulette connects a single-zero wheel, a ball and a number layout. 123mkv explains its numbered pockets, grouped selections and result reading.
Context and practical meaning
A European wheel has zero and the numbers one through thirty-six. The wheel order differs from the table layout. Numbers next to each other on the cloth may therefore be far apart on the wheel.
A single number differs from a group such as red/black or odd/even. Zero belongs to neither red/black nor the ordinary odd/even groups. Covering more numbers does not remove risk.
After a round closes, the pocket in which the ball settles determines the result. A previous run of red or black does not compel the next outcome. The single-zero European layout should not be confused with an American double-zero version.
Points requiring attention
Single selection
An outcome on one specific number.
Groups
Colours, odd/even and other number sets.
Independence
Past sequences do not guarantee future outcomes.
A closer look at real situations
A chip’s position on the layout may refer to one number or several. A line or corner position should not be mistaken for a single-number selection.
The result field differs from the history strip. Do not infer the current result from a previous number before the current round is confirmed.
Questions about European roulette
Is zero part of even?
Zero is not included in ordinary roulette odd/even selections.
Is wheel order the same as the cloth?
No. Adjacent layout numbers do not necessarily sit together on the wheel.
Is black certain after many reds?
No. Earlier colours do not force the next result.
Is a double-zero version identical?
No. Additional pockets change the structure; this page covers single zero.
