Building a math-first poker engine in .NET

This started as a solo engineering project, and it has grown into something much more interesting than a simple side experiment.

I’ve been building a Texas Hold’em toolkit in C# focused on:

bitwise data manipulation
Monte Carlo equity estimation
extensible game-state abstractions
a low-level math-first design without relying on lookup tables

The core idea is not just to compute odds, but to build a reusable platform for poker analysis and strategy modeling with clean abstractions and strong performance characteristics.

The project already includes:

low-level card and rank primitives
Texas Hold’em-specific logic
CLI tooling for range-vs-range estimation
benchmark projects for performance validation

Current benchmark results for 10,000 Monte Carlo simulations:

2 players: ~284.5 ms
3 players: ~448.3 ms
4 players: ~628.7 ms

This is still early, but the foundation is solid and there is a lot of space to evolve into deeper GTO-style work, more advanced equity modeling, and broader tooling.

This project is now open for collaboration and contributors; if you are interested in:

poker math
algorithmic optimization
C# / .NET
simulation systems
performance engineering
open-source game-analysis tools

I’d love to connect and build this further together.
