About the Job

Requirements

Proven experience as a slot mathematician or game mathematician in iGaming.
Deep command of probability theory, statistics, and combinatorial analysis.
Experience building and validating PAR sheets and simulation models.
Understanding of ultra-high return-to-player rates, including how near-zero edge affects variance and exposure.
Proficiency in simulation tools and scripting such as CUDA or Rust.
Understanding of provably fair systems and how game mathematics interacts with cryptographic verification.

Responsibilities

Design and validate game-math models for original slots and house games.
Define return-to-player rates, variance, hit rates, pay tables, and bonus-round mechanics.
Simulate millions of rounds to stress-test edge cases before release.
Work with game designers and engineers to translate mathematics into playable experiences.
Model extreme-variance scenarios, particularly the effects of near-zero edge on outcomes.
Ensure game mathematics is compatible with provably fair verification.
Analyze live game performance against theoretical models and flag deviations.
Contribute to player-versus-player and prediction-market mechanics that require probability modeling.

Workplace: remote

Department: Risk & Compliance

Description

Duel is a protest against everything wrong in gambling. The purest, fairest casino ever built. The Vatican of gamba. We're waging holy war on scammers, fake bets, and dark patterns; and we need someone to build the math that makes provably fair games actually work.

The role

You own the numbers behind every original game we ship. RTP, volatility, hit frequency, pay tables, bonus mechanics, all of it. Duel runs at 99.9–100% RTP. That means the math has to be perfect. There's no fat margin to hide behind. Every model you build will be provably fair and publicly verifiable, which means every model you build has to be bulletproof.

This isn't tweaking pay tables on someone else's slot. You're designing the mathematical foundations of games that have never existed before.

What you'll do

Design and validate game math models for original Duel slots and house games
Define RTP, variance, hit rates, pay tables, and bonus round mechanics
Simulate millions of rounds to stress-test every edge case before anything ships
Work directly with game designers and engineers to translate math into playable experiences
Model extreme variance scenarios - at near-zero edge, the tails matter more than anywhere else
Ensure all game math is compatible with provably fair verification
Analyse live game performance against theoretical models and flag drift
Contribute to PvP and prediction market mechanics where probability modelling is needed

What you'll need

Proven experience as a slot mathematician or game mathematician in iGaming
Deep command of probability theory, statistics, and combinatorial analysis
Experience building and validating PAR sheets and simulation models
Comfortable working at ultra-high RTP: you understand what near-zero edge does to variance and exposure
Proficient in simulation tools and scripting (CUDA, Rust, or similar)
Understanding of provably fair systems and how game math interacts with cryptographic verification
Meticulous. At these margins, a rounding error is a crisis.

Come build the math behind the fairest games ever made.
