Roulette offers more bet types than almost any other casino game, ranging from near 50/50 bets to long-shot single number wagers. Understanding what each bet pays and its probability of winning is step one for any beginner.
The table below uses European roulette (single zero, 37 total numbers: 0-36), which is the standard for most crypto casinos including SPUNK.BET.
| Bet Type | Coverage | Payout | Win Probability | House Edge |
|---|---|---|---|---|
| Straight Up | 1 number | 35:1 | 2.70% | 2.70% |
| Split | 2 numbers | 17:1 | 5.41% | 2.70% |
| Street | 3 numbers | 11:1 | 8.11% | 2.70% |
| Corner | 4 numbers | 8:1 | 10.81% | 2.70% |
| Six Line | 6 numbers | 5:1 | 16.22% | 2.70% |
| Dozen | 12 numbers | 2:1 | 32.43% | 2.70% |
| Column | 12 numbers | 2:1 | 32.43% | 2.70% |
| Red/Black | 18 numbers | 1:1 | 48.65% | 2.70% |
| Odd/Even | 18 numbers | 1:1 | 48.65% | 2.70% |
| High/Low | 18 numbers | 1:1 | 48.65% | 2.70% |
Notice that every bet on a European roulette table has the same house edge: 2.70%. Whether you bet on a single number or Red/Black, the casino takes the same percentage cut over time. The difference is volatility: outside bets (Red/Black, Odd/Even) win often but pay small, while inside bets (Straight Up) win rarely but pay large.
The house edge is the mathematical advantage the casino has over you on every bet. In European roulette, it exists because the payout for a Straight Up bet is 35:1, but the true odds are 36:1 (36 non-winning numbers out of 37 total). That one-unit gap is the house's profit margin.
| Variant | Numbers on Wheel | Zero Slots | House Edge |
|---|---|---|---|
| European | 37 (0-36) | Single zero | 2.70% |
| French (La Partage) | 37 (0-36) | Single zero | 1.35% on even-money bets |
| American | 38 (0, 00, 1-36) | Double zero | 5.26% |
Always play European roulette. American roulette nearly doubles the house edge with its extra "00" slot, and you get no additional benefit. If French rules (La Partage) are available, even-money bets have a house edge of just 1.35%, making it the best roulette variant for players.
For every 10,000 SPUNK you wager in total over a session, you will lose an average of 270 SPUNK. This is the long-term average, not a per-spin guarantee. In a short session, you might win big or lose big. But over hundreds of spins, your results will converge toward losing 2.70% of your total wagered amount.
Betting systems are structured approaches to adjusting your bet size based on previous results. None of them can change the house edge, but they dramatically affect the pattern of your wins and losses. Understanding the tradeoffs helps you pick the right approach for your bankroll and risk tolerance.
| System | How It Works | Bet After Loss | Bet After Win | Risk Level |
|---|---|---|---|---|
| Martingale | Double your bet after each loss | 2x previous bet | Reset to base bet | Very High |
| D'Alembert | Increase by 1 unit after loss, decrease by 1 after win | +1 unit | -1 unit | Moderate |
| Fibonacci | Follow the Fibonacci sequence after losses | Next Fibonacci number | Go back 2 numbers | High |
| Flat Betting | Same bet every round | No change | No change | Low |
How it works: Start with 100 SPUNK. If you lose, bet 200. Lose again, bet 400. Keep doubling until you win, then reset. When you eventually win, you recover all losses plus one base bet profit. The problem: After 7 consecutive losses (which happens more often than you think at ~48.65% win rate), your next bet would be 12,800 SPUNK — 128x your starting bet. Most bankrolls and table limits cannot sustain this. One bad streak wipes out hundreds of small wins.
How it works: Start with a 5-unit bet (500 SPUNK if your unit is 100). After a loss, increase by 1 unit (600). After a win, decrease by 1 unit (400). The advantage: Much less aggressive than Martingale. Your bets escalate slowly, which protects your bankroll during losing streaks. The downside: Recovery from deep losing streaks is slow, and the system still does not change the underlying house edge.
How it works: Bet sizes follow the Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13, 21... After each loss, move to the next number. After a win, go back two numbers. The middle ground: Less aggressive than Martingale but faster recovery than D'Alembert. Bets grow exponentially but slower than doubling. After 7 losses your bet is 13 units instead of 128 units (Martingale).
| System | Max Bet Size Reached | Biggest Drawdown | Bankroll Needed | Bust Risk |
|---|---|---|---|---|
| Martingale | 128x base | 255 units | 500+ units | High |
| D'Alembert | ~15x base | ~60 units | 100+ units | Low-Medium |
| Fibonacci | ~34x base | ~88 units | 150+ units | Medium |
| Flat Betting | 1x base | ~15 units | 50+ units | Very Low |
Recommendation for beginners: Use flat betting or D'Alembert. They keep you in the game longest and give you the most spins for your bankroll. Martingale is exciting but dangerous. Fibonacci is a reasonable middle ground if you want some escalation without Martingale's extremes.
The most important roulette skill is not picking the right number — it is managing your money so you can survive losing streaks and still be playing when the wins come.
| Rule | Conservative | Moderate | Aggressive |
|---|---|---|---|
| Session Budget | 10% of total bankroll | 20% of total bankroll | 30% of total bankroll |
| Bet Size | 1% of session budget | 2% of session budget | 3% of session budget |
| Stop-Loss | 50% of session budget | 70% of session budget | 90% of session budget |
| Win Target | 25% profit | 50% profit | 100% profit |
| Spin Limit | 50 spins | 100 spins | 200 spins |
Reality: Every spin is independent. The wheel has no memory. After 5 blacks, the probability of the next spin being Red is still 48.65%. After 50 blacks (astronomically unlikely but theoretically possible), it is still 48.65%. This is the gambler's fallacy, and it is the single most common mistake in roulette.
Reality: No betting system — Martingale, D'Alembert, Fibonacci, Labouchere, or any other — can change the house edge. They change the distribution of your wins and losses (lots of small wins vs. rare big losses, for example), but the expected loss over time is identical. The house edge is built into the payout structure, not the bet pattern.
Reality: In physical casinos, some players believe dealers develop a consistent throw that lands in predictable sectors. In crypto roulette, this is completely irrelevant because outcomes are determined by a cryptographic random number generator. There is no wheel, no ball, no physics to exploit. The result is provably random.
Reality: In European roulette, every bet has the same 2.70% house edge. A Straight Up bet on number 17 has the same expected return as a bet on Red. The difference is volatility: inside bets have bigger swings (rare big wins), outside bets have smaller swings (frequent small wins). Neither is mathematically "better."

Play Roulette FreeStart with flat betting on outside bets (Red/Black or Odd/Even). Bet 1-2% of your session bankroll per spin, set a stop-loss at 50% of your budget, and cap your session at 50 spins. This approach gives you the most playing time, the smoothest experience, and the least risk of going bust quickly. Once you are comfortable, you can experiment with D'Alembert or Fibonacci systems.
No. Roulette has a built-in house edge (2.70% in European) that cannot be overcome by any strategy, system, or approach over the long term. For every $10,000 wagered, you will lose an average of $270. Professional gambling exists in games with player edges (poker, sports betting with information advantages), but roulette is not one of them. Play it for entertainment, not income.
At provably fair casinos like SPUNK.BET, no. Provably fair means the outcome of each spin is determined by a cryptographic seed that you can verify independently after the round. The casino cannot change the result after your bet is placed. Always play at provably fair platforms and verify results periodically. Unverifiable roulette at unknown sites is a different story — stick to platforms that let you audit outcomes.
