# Open Algorithms & Code

Every algorithm that shapes your experience is documented here — in plain language, with the actual formulas, and direct links to the source code.

When an algorithm decides who sees your profile, how your reliability is scored, or which games appear in your feed — those decisions affect real-world interactions. A late-cancel penalty isn't just a number; it's the difference between a full table and a cancelled game night.

We believe you deserve to understand how every scoring and matching system works. Not in vague marketing terms — in actual math, with the real weights, thresholds, and design tradeoffs explained.

Each section below documents one of our algorithm systems. You'll find the formula, the reasoning behind key decisions, and a direct link to the source code on GitHub. If something seems wrong, you can open an issue.
