Roulette Statistics

American straight bets hit a chosen number only 1/38 of the time, about 2.6316%, while European gives you 1/37 or roughly 2.7027%, and that small tilt grows into house edges of about 5.26% versus 2.70%. See how every payout and outcome tier shifts, from red and black probabilities to dozens and columns, so you can finally compare odds side by side on the same page.

Statistics that fail independent corroboration are excluded.

A single number lands at 2.6316% on American roulette, but only 2.7027% on European, a small shift caused by the extra zero. That difference compounds into house edges of about 5.26% versus 2.70% for straight bets, even though payout charts tempt you with neat 35 to 1 odds. Let’s compare how often each bet type wins, including why even a “50 50” like red still loses more often on American than on European.

Key Takeaways

  • The probability of landing on a single specified number on an American roulette wheel is 1/38 (≈2.6316%), because there are 38 possible outcomes on an American wheel.
  • The probability of landing on a single specified number on a European roulette wheel is 1/37 (≈2.7027%), because there are 37 possible outcomes on a European wheel.
  • The probability of landing on red on a European roulette wheel is 18/37 (≈48.6486%).

Straight bets hit a specific number about 2.70% on European wheels and 2.63% on American, powering higher house edge.

Odds & Probabilities Interpretation

Whether you bet on one magic number, a whole color, or an entire dozen, roulette always finds a way to be “fair” in the math and unfair in the payout, with European odds of 1 in 37 (about 2.70 percent) and American odds of 1 in 38 (about 2.63 percent) plus the extra zeros quietly taking an average house edge of about 2.70 percent on straight bets in Europe and about 5.26 percent in America.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source
ChatGPTClaudeGeminiPerplexity

Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.

AI consensus: 1 of 4 models agree

Directional
ChatGPTClaudeGeminiPerplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified
ChatGPTClaudeGeminiPerplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.

AI consensus: 4 of 4 models fully agree
