Outside bets (Red/Black, Even/Odd, High/Low) have the best probability (48.65%) but only pay 1:1. They're perfect for beginners and betting systems like Martingale. Inside bets offer higher payouts but lower probability - use them for occasional big win attempts.
Castle Roulette Strategies
🎯 Recommended Strategies
Martingale System
High RiskDouble after every loss on even-money bets (Red/Black, Even/Odd).
- Loss: Bet $2 on Red
- Loss: Bet $4 on Red
- Win: Profit $1, reset to $1
- Guaranteed profit after any win
- Simple to implement
- Requires large bankroll
- Table limits will stop you
- Risk of long losing streaks
D'Alembert System
Medium RiskIncrease by 1 unit after loss, decrease by 1 after win on even-money bets.
- Loss: Bet $10
- Win: Bet $5
- Win: Bet $5 (minimum)
- Less aggressive than Martingale
- Works with moderate bankroll
- Slow profit accumulation
- Can still hit losing streaks
Fibonacci System
Medium RiskFollow Fibonacci sequence after losses, move back two steps after win.
- Loss: $1 → $1 → $2 → $3
- Win: Move back two steps
- Mathematically interesting
- More gradual progression
- Complex to track
- Still requires bankroll
🔢 Number Pattern Strategies
Hot Numbers
Bet on numbers that have appeared frequently in recent spins. Works on the theory of temporary "hot streaks".
Cold Numbers
Bet on numbers that haven't appeared in many spins. Based on "regression to the mean" theory.
Neighbor Bets
Bet on a number and its neighbors on the wheel (not the layout). Based on dealer patterns.
⚠️ Strategy Warning:
No roulette strategy can overcome the 2.7% house edge in the long run. Each spin is independent and random. Strategies manage your bankroll and provide structured betting, but they don't change the odds. The house always has an edge.

Castle Roulette FAQ
97.3% RTP comes from the European single-zero wheel. With 37 numbers (0-36), the true odds are 36:1 for straight up bets, but the payout is 35:1. This creates a 2.7% house edge (100% - 97.3%). European roulette has better RTP than American (94.74%).
No betting system can overcome the mathematical house edge in the long run. Systems like Martingale can provide short-term wins but risk catastrophic losses. The house edge of 2.7% means over thousands of spins, you'll lose 2.7% of total money wagered.
Start with even-money outside bets: Red/Black, Even/Odd, or High/Low (1-18/19-36). These have 48.65% probability of winning each spin (excluding zero). They're simple, have frequent wins, and work well with conservative betting systems.
Statistically, no number is luckier than others. However, many players have preferences: 17 (center of layout), 7 (lucky number), 0 (house number), or birthdays. In Castle Roulette, track hot/cold numbers in the statistics to inform your bets.
Castle Roulette has approximately 45-60 seconds between spins. This includes 30 seconds for betting, 15 seconds for spinning and ball landing, and 15 seconds for payout. This pace allows strategic betting and is faster than physical casinos but not overwhelming.
Yes! Duel Casino's interface allows multiple bets per spin. You could combine: Martingale on Red/Black, while also betting on hot numbers. However, manage your total bet per spin (table max is typically $10,000 for VIP players).
