Duel Original · 6×5 grid
A 6×5 grid game with a sweet-shop theme and a nasty streak.
No published algorithm. Added in September 2026. Grid games resolve against a paytable with thousands of outcomes, so unlike Dice or Castle Roulette there’s no quick sum that confirms the return — you can check any individual round, but not the overall figure.
How to play
Set your stake and spin the 6×5 grid.
Wins resolve against the game’s paytable and feature rules.
Read the rules panel before your first spin — features drive most of the return.
You can still check any round afterwards in the fairness panel.
Playing it well
On Castle Roulette you can prove the odds with two numbers. Here you can’t — the paytable is too big to add up from the outside. That doesn’t make it unfair, but it is a different kind of confidence, and worth knowing the difference.
Like a slot, this is built around long stretches of nothing broken up by the occasional big hit. If you are used to the steady rhythm of Dice, it will feel brutal. Bet smaller than you think you should.
Quick check. You can confirm any individual round from the seed pair in the fairness panel. What you cannot do is reconstruct the paytable to check the advertised return.
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.
This is a grid game, so it works like a slot: symbols land, features trigger, and the payouts come from a table with thousands of combinations in it.
That means you cannot check the odds yourself the way you can on Dice or Castle Roulette. You can still confirm any individual round was not tampered with — you just have to take the overall return on trust.
| Game | Can you check the odds? | Can you check a round? |
|---|---|---|
| Castle Roulette | Yes, in your head | Yes |
| Dice, Plinko | Yes, in seconds | Yes |
| Mines, Keno | Yes, with a spreadsheet | Yes |
| Blackjack, Video Poker | Only the rules | Yes |
| Groomer's Van | No | Yes |
FAQ
It is an in-house grid game rather than a licensed third-party title, so it sits in the Originals category and carries the provably-fair system. Mechanically it has far more in common with a slot than with Dice.
Your own client seed is mixed into every result, so once Duel reveals the server seed you can recalculate any round offline.
