Flat betting in roulette means you always wager the same stake on every spin, no matter if you just won or lost, instead of increasing or decreasing your bets like with Martingale‑style systems.

What flat betting is

  • You choose a fixed unit (for example €2 or €5) and keep that exact bet size every spin.
  • You can use it on even‑money bets (red/black, odd/even, high/low) or on any other layout (single numbers, dozens, etc.); the key is that the amount per spin never changes.
  • It contrasts with progressive systems like Martingale or Paroli, where you adjust your stake after each loss or win.

In other words: same chip size, every spin, regardless of the outcome.

How to do flat betting (step‑by‑step)

  1. Decide your bankroll
    • Example: you bring €200 to a roulette session.
  2. Choose a fixed unit
    • A common guideline is 1–2% of your bankroll per spin, e.g. €2–€4 on a €200 bankroll, so you can survive longer streaks.
  3. Pick your bet type
    • Many players use flat betting on even‑money bets like red/black or odd/even to get frequent hits and smoother swings.
    • You can also flat‑bet on a specific number or section (e.g. always €1 on number 17 every spin).
  4. Place the same bet every spin
    • Example even‑money: bet €2 on red every spin for 50 spins → you risk €100 total if you play all 50.
    • Example straight‑up: bet €1 on number 16 for 25 spins → you wager €25 total; if 16 hits once, you get 35:1 (= €35 profit on that spin, minus your previous losses).
  5. Stop when you hit your limit
    • Before you start, set a max loss (e.g. half the bankroll) and maybe a win target, then quit when you reach it.

Risks and downsides

  • House edge still wins long term
    • Flat betting does not change the inherent house edge (about 2.7% on European roulette, ~5.26% on American), so over many spins you statistically lose slowly to the casino.
  • Limited profit potential
    • Because you never increase stakes on winning streaks, you usually only see modest, gradual profits when you run hot.
  • Slow grind of losses
    • The upside is you rarely blow up a bankroll in a few spins, but the downside is the edge “grinds you down” over time; you can have many small losing sessions.
  • Can feel boring or repetitive
    • Some players find always betting the same amount dull compared with systems where stakes move up and down.

Upsides compared to progressive systems

  • Better control over losses
    • You always know your maximum exposure; for example, with €200 and flat €5 bets over 20 spins, your worst‑case loss is €100 if you play every spin.
  • Lower risk of ruin
    • You avoid the huge bet sizes that happen in systems like Martingale after a losing streak, reducing the chance of hitting table limits or going bust in a few spins.
  • Very simple to execute
    • No calculations or tracking progression, which makes it attractive for beginners who mainly want a controlled, longer roulette session.
