Duel Originals: All Games and Their Payouts
Duel Originals are the platform's own games, developed in-house rather than acquired from studios. There are eleven of them, and each card bears the same label: 100% RTP.
This label is the platform's main selling point and the primary reason for questions. Let's break down what truly lies behind it.
What's Included
| Game | Mechanics |
|---|---|
| Mines | 5x5 field, open tiles and avoid hitting a mine |
| Plinko | ball drops through pegs into a cell with a multiplier |
| Blackjack | classic 3:2, reshuffle every hand |
| Dice | set a threshold and guess if the number will be higher or lower |
| Crash | cash out before the graph crashes |
| Keno | choose numbers, matches give a multiplier |
| Video Poker | five-card draw |
| Castle Roulette | live wheel in a show format |
| Beef | original platform mechanic |
| Groomer's Van | slot-like game |
| Rock Paper Scissors | rock-paper-scissors for money |
The first three are covered on separate pages, where you'll find formulas, payout tables, and verification of the stated return.
What 100% RTP Means
Literally: the mathematical expectation of a round is zero. The casino does not take its percentage.
To understand the scale, it's worth comparing. Stake Originals have a house edge of 1%, which is still considered a market benchmark. The average online slot has about 4%. European roulette has 2.7%, American roulette 5.26%. Zero is an order of magnitude better than the best.
It's important not to confuse two statements here:
True: over an infinite distance, your balance tends towards its initial value, rather than decreasing.
False: you will be in profit. Zero is zero. The game stops being paid, but it doesn't become profitable.
The difference is fundamental because variance doesn't disappear with zero mathematical expectation. A session of a hundred rounds can end with a doubled balance or a complete zero. The only thing that changes is that the average across all possible sessions is now exactly in the middle, not skewed in favor of the casino.
We Checked and Found a Discrepancy
The "one hundred percent" claim is verifiable if the game has a published payout table. We took Plinko on sixteen rows with high risk and calculated the return: the sum of all multipliers, weighted by the probability of hitting a cell.
The result was 99.196%, not 100%.
The reason is most likely in the interface: the extreme cell is labeled "1k," meaning rounded. For the sum to exactly equal one hundred percent, the extreme cell should pay around 1263x, and then everything falls into place. The extreme cell appears once every 32,768 drops, so it's precisely on this cell that the missing eight-tenths of a percent can be hung, without touching anything else.
The conclusion is not "we are being deceived," but "check the exact value in the game." A detailed analysis with a breakdown by positions is available on the Plinko page.
Another telling point: the Duel table is the Stake table with two adjusted cells. Nine became 9.1, one hundred thirty became 131. This is exactly how the transition from 99% to 100% should look if the grid is minimally changed.
How Formulas Change Without Commission
This is most clearly seen in Mines. The multiplier is calculated by the number of combinations, and in Stake, the result is multiplied by 0.99 — that very commission. Duel does not have this multiplier.
| Layout | Duel | Stake |
|---|---|---|
| 3 mines, 1 diamond | 1.14x | 1.13x |
| 5 mines, 5 diamonds | 3.43x | 3.39x |
| 10 mines, 5 diamonds | 17.69x | 17.52x |
| 24 mines, 1 diamond | 25.00x | 24.75x |
| 12 mines, 12 diamonds | 400,023x | 396,023x |
The difference is exactly one percent on each cell — no more, no less. This is the entire effect of zero edge, if expressed in multipliers.
Provably fair
All Originals operate on the same scheme. The round result is assembled from the server seed, your client seed, and the bet number, run through HMAC-SHA256, and the resulting hash is translated into the outcome — mine placement, ball path, card order.
The server seed is fixed before the round, and its hash is shown in advance. It is impossible to change the result after you have placed a bet — the hash will no longer match, and anyone can verify it.
The flip side of the same fact: it is also impossible to predict the result. Until the server seed is revealed, no information about it exists in any form. All "predictors" for Mines, Crash, and Plinko are either random image generators or funnels to affiliate links.
How does a casino without a margin survive?
The first and correct question that arises. If proprietary games bring nothing, where does the money come from?
In short: from slots by third-party studios, from sports betting, and from the affiliate program. Originals work as a lure — they are free in terms of mathematical expectation and attract traffic, and the platform earns on everything else. We analyze the model in detail on the page about zero house edge.
Frequently Asked Questions
Do Duel Originals really have zero commission? According to the formulas — yes. Checking the Plinko table showed 99.196% due to rounding of the extreme cell in the interface; with the exact value, it converges to 100%.
Does this mean you can win on them? No. Zero mathematical expectation means breakeven over an infinite distance, not profit.
How do they differ from Stake Originals? By one percent commission. The mechanics, formulas, and provably fair scheme are the same.
Is there a demo mode? Proprietary games are launched with a balance; they do not have a separate demo.
Do settings change the payout? No. The number of mines, risk level, number of rows — all this changes the variance, but not the mathematical expectation.
All calculations on this page were performed by us according to the published tables and game formulas. We do not place affiliate links.
