Show HN: Poker hand evaluator in pure C# (.NET 8) – 115M evals/SEC

https://github.com/JBelthoff/poker.net
3•jbelthoff•3mo ago
I rebuilt the classic Cactus Kev poker hand evaluator from scratch in modern C# (.NET 8), focusing on algorithmic clarity and performance instead of lookup tables.

• Pure C#, no unsafe code • Evaluates ~115 million 7-card hands per second • Uses Span<T> and BenchmarkDotNet • Detailed benchmarks and architecture in the README

Thanks for checking this out! If you’re curious about how I squeezed 115 million 7-card evaluations per second in .NET 8, ask away — happy to dig into the combinatorial logic, Span<T> usage, or BenchmarkDotNet setup.

How are these not lookup tables?

jbelthoff•3mo ago
Good question - only one of those, (flushes), is even remotely “lookup-table-ish,” and that’s just a small optimization for detecting flush patterns. It’s not a precomputed hand-rank database.

The evaluator doesn’t rely on massive precomputed tables like SnapCall (platatat/SnapCall) or HenryRLee/PokerHandEvaluator versions. Every hand is still scored in real time through arithmetic and bit logic - prime products, masks, and combinatorial iteration.

hand_rank_jb is the actual evaluation logic, and perm7 just enumerates 7-card combinations. Neither of those stores results. So while there’s a minor mapping array for flush detection, the overall approach remains a pure C# implementation without traditional lookup tables or unsafe code.
