About: This roulette simulator lets you spin the wheel as many times as you want and track patterns in the numbers.
You can choose a condition to highlight certain numbers—like Red 2nd and 3rd dozen or Black 1st and 2nd dozen.
The simulator will display all numbers in sequence and add a subtle glow to the ones matching your chosen condition.
It also calculates important statistics:
- Longest gap: the largest number of spins between hits for your selected condition.
- Shortest gap: the smallest number of spins between hits.
- Average gap: the average number of spins between hits.
- All gaps: a list of every gap, sorted from longest to shortest.
Pushbacks: Some spins neither win nor lose, but instead return your stake—for example when the color misses but the dozen lands, or the dozen misses but the color lands. These are called pushbacks. Inside the visual gap display, pushbacks appear with a small yellow "p" in the bottom-right corner of the number. This makes it easy to count how many times your bet was pushed back during long streaks.
Why this matters: When using betting strategies based on dozens or similar groups, you can experience streaks, gaps, and pushbacks. This simulator highlights them so you can explore probabilities and plan strategies safely!
