Duel Original · Spin
Roulette with the zero-pocket advantage taken out of the payouts.
How to play
Choose a band to back, from the single 48× pocket down to the 2× half.
The paytable is shown before you commit.
Spin. The pocket it lands in was already decided before the wheel started turning.
Winning bets pay the posted multiplier.
Playing it well
Backing a single pocket and backing half the wheel come to the same thing over time. One pays 48× and almost never lands; the other pays 2× and lands half the time. Pick whichever you enjoy more — neither is the smarter bet.
On most games you have to trust the number on screen. Here you can check it yourself with two figures anyone can see: there are 48 pockets, and one pocket pays 48×. That is the whole proof.
Martingale, Fibonacci and the rest just shuffle your wins and losses into a different order. They do not make a fair game better or a bad game worse. Betting the same amount every spin gets you to the same place with fewer heart attacks.
Quick check. Multiply any band’s payout by the pockets it covers. If the answer is 48 — the pocket count — the edge on that bet is exactly zero. All six bands pass.
Fair odds are not a winning system. Taking the casino’s advantage away does not hand you one. The best any of these games does is break even over time, and a bad night can still take everything you brought. Decide what you are willing to lose before you open the game, not halfway through it.
What it pays
The numbers below are what actually lands in your balance, using a $10 bet as the example.
The wheel has 48 pockets. Back one pocket and it pays 48×. Back two and it pays 24×. Back half the wheel and it pays 2×. Every bet on the table is priced the same way.
That is what makes it exactly fair. A real roulette wheel has 37 pockets but only pays 36× on a single number, and that one missing pocket is the casino’s entire profit.
| Your bet | Covers | Pays | A $10 bet returns |
|---|---|---|---|
| One pocket | 1 of 48 | 48× | $480 |
| Two pockets | 2 of 48 | 24× | $240 |
| Three pockets | 3 of 48 | 16× | $160 |
| Six pockets | 6 of 48 | 8× | $80 |
| Twelve pockets | 12 of 48 | 4× | $40 |
| Half the wheel | 24 of 48 | 2× | $20 |
FAQ
By paying true odds against the pocket count. Standard roulette has 37 or 38 pockets but pays a single number 36×, and that gap is the margin. Castle Roulette has 48 pockets and pays a single pocket 48×, so there is no gap.
48 divides cleanly into 1, 2, 3, 6, 12 and 24, which is what lets every payout band be an exact whole-number multiple. A 37-pocket wheel cannot produce a clean fair paytable, which is part of why real roulette has an edge at all.
No rejection threshold is documented. 2³² is not an exact multiple of 48, so a vanishingly small modulo bias exists in principle — on the order of one part in ninety million.
Uses a public randomness beacon that nobody controls. Duel locks in which beacon round it will use before that randomness exists, so neither side can know the result in advance.
