Duel just dropped a new slot called Groomer's Van. No announcement, no marketing push. It just appeared in the lobby. We noticed and went straight in to check it out.
The Game
Groomer's Van is a slot game on Duel Casino. Like Castle Roulette, it runs at 100% RTP with provably fair outcomes using the same HMAC-SHA256 verification system. The game is provably fair, and we have no reason to doubt that claim based on what we have seen so far.

The Roobet Connection
The game is clearly a diss aimed at Roobet. The main character is a kangaroo that looks a lot like Roobet's brand mascot. See for yourself:

The name itself is provocative. When players hit wins, the game pops up messages like "Found you" and "Groomed" -- which some regulators might frown upon regardless of how the community feels about it.
Whether you think it is funny or over the line, it is definitely not subtle.
How It Plays
The game plays like a standard video slot. Multiple paylines, a base game with regular spins, and a bonus feature. The visuals are decent for what Duel usually puts out. Nothing groundbreaking, but it works.
What stands out is the 100% RTP. Most slots run between 94-97% RTP. A slot at 100% means the house has zero mathematical edge over time. That is revolutionary for any casino, let alone a crypto one.
Castle Roulette Set the Bar
We already did a full audit on Castle Roulette with over 400,000 rounds of data. That game checks out -- the math is clean, the RTP holds, and the provably fair system works as advertised.
Castle Roulette is simple. You pick a multiplier, the wheel spins, you win or lose. It is easy to verify because the game is transparent about its wheel layout and probabilities.
Slots are harder to audit. The RNG determines symbol combinations across multiple reels and paylines. Even with provably fair verification, you need a much larger sample size to confirm the actual RTP matches the claimed RTP.
We have not run the numbers on Groomer's Van yet. This article is a first look, not an audit. We plan to give it the same treatment we gave Castle Roulette once we have enough data.
What We Think So Far
A 100% RTP slot is a big deal. If the math holds up the same way it did with Castle Roulette, Duel is doing something genuinely different in this space. The theme is wild and the in-game messaging might attract unwanted regulatory attention, but the game mechanics look solid.
We will keep an eye on it and come back with the numbers.
