Rainbet's Withdrawal Cap Problem
Rainbet restricts your withdrawals to €5,000 per day, €50,000 per week, and €100,000 per month. For high-volume players or big winners, these artificial limits become a serious problem.
Example: €100K Win on Rainbet
Your €100K win takes 20 days to fully withdraw. During this time, your funds remain locked on the platform.
Same €100K Win on Duel
Full withdrawal processed instantly with no caps, no delays, no restrictions. Your money, your control.
RTP & House Edge Analysis
| Return to Player | Duel Casino | Rainbet |
|---|---|---|
| Originals RTP | 100% | 96% typical |
| Zero Edge Mode | 0% house edge | Not available |
| Effective RTP (Zero Edge) | 100% | 96% |
| Provably Fair Games | All Originals | 8 games only |
Duel's Math Advantage
Zero Edge Windows:
0% house edge = 0% expected loss
€100K wagered at 0% edge:
€0 expected loss
€1M wagered at 0% edge:
€0 expected loss
With Zero Edge mode, you're playing pure variance with no mathematical disadvantage. Every bet has fair odds.
Rainbet's 4% Edge Cost
Standard 96% RTP:
4% house edge = 4% expected loss
€100K wagered at 4% edge:
€4,000 expected loss
€1M wagered at 4% edge:
€40,000 expected loss
The 4% edge compounds with every bet. Over significant volume, this mathematical disadvantage costs serious money.
How 4% Edge Destroys Your Bankroll Over Time
| Total Wagered | Duel (0% Edge) | Rainbet (4% Edge) | Difference |
|---|---|---|---|
| €50,000 | -€0 | -€2,000 | €2,000 saved |
| €100,000 | -€0 | -€4,000 | €4,000 saved |
| €500,000 | -€0 | -€20,000 | €20,000 saved |
| €1,000,000 | -€0 | -€40,000 | €40,000 saved |
These are expected values - the mathematical reality of house edge over volume. Zero edge means zero expected loss.

Duel: Complete Provably Fair Verification
Every single bet on Duel Originals (Crash, Dice, Plinko, Mines, Blackjack, Beef) uses full cryptographic verification that you can audit yourself:
Duel commits to a server seed before you place the bet. You see the hash, proving it can't be changed.
You provide or modify your client seed. This ensures Duel can't manipulate outcomes even if they wanted to.
Each bet increments the nonce, creating a unique combination for every single game round.
After the bet, verify the outcome yourself using the revealed server seed. The math must match exactly.
Bottom line: Duel can't cheat even if compromised
The cryptographic commitment system makes manipulation mathematically impossible. You control the client seed, Duel commits to the server seed before you bet, and you can verify everything independently.
Rainbet: Limited Provably Fair
Rainbet offers provably fair on only 8 in-house games: dice, limbo, blackjack, mines, keno, plinko, case battle, and case opening.
What about the other 6,000+ games?
The vast majority of Rainbet's library consists of third-party slots from providers like Pragmatic Play, NetEnt, and Hacksaw. These games use standard provider RTP with no per-bet verification. You must trust the provider's RTP claims without independent verification.

Which platform has better bonuses - Duel's rakeback or Rainbet's welcome bonus?▼
Duel's rakeback with code JOY has zero wagering requirements and is credited in real-time. You can withdraw it immediately with no restrictions. Rainbet's welcome bonus requires 40x rollover, must be completed in 7 days, restricts max bet to 1% of deposit, and locks your funds until wagering is complete.
