Roulette spins are independent — past results never influence the next spin, and "hot" or "cold" streaks don't change the odds. This tracker is for fun and observation only, not a betting system. Please play responsibly. 18+.
Using the roulette number tracker
This tracker logs every spin you tap and instantly updates your statistics: which numbers are running hot, which are cold, and how the results split across red/black, odd/even and 1–18 / 19–36. It's a great way to visualise how randomness actually behaves at the wheel.
What "hot" and "cold" really mean
Over a short run, some numbers naturally appear more than others — that's variance, not a pattern. A European wheel has 37 pockets, so each number has a 1 in 37 chance on every spin, every time. The wheel has no memory: a number being "cold" doesn't make it "due".
The gambler's fallacy
- Each spin is independent — previous outcomes don't affect the next.
- Chasing hot or cold numbers doesn't improve your odds.
- The single zero is where the house edge lives (about 2.7% on European roulette).
