Hattrick Codex is in beta: we're still polishing texts and data, so you may spot a few imperfections. Found a mistake or have an idea? Send me an HT-Mail in game: every report makes the Codex better for everyone.
Created by Dema_Jr and built with Kriptico: thirty years of community studies, collected, organised and made easy to read.
Based on the public collections and studies of the Hattrick community · LA-Alpa, nickarana, glynzales, NRGJACK, Kriptico
Where to start
Three parts, like a season: who you send out, what happens in the match, how the club grows.
Who makes the Codex
Hattrick Codex was born from an idea by Dema_Jr and is curated together with Kriptico: we choose the sources, check them and turn them into pages, charts and calculators that are easy to use.

Came up with the Codex and looks after its structure, texts and design. Has been making Hattrick content for years and is an NT Coach.

Reviews and expands the content and wrote the Complete Youth Academy Guide with the Italian U17 staff.
The people behind the numbers
Hattrick Codex exists thanks to the people who spent years collecting matches, crunching the numbers and explaining the rules on the Hattrick forum. Every figure on this site links to their original post.
165 forum posts cited, 18 chapters, 7 calculators, in English, Italian and Spanish. See all sources
Thirty years of answers, finally in one place.
I've been making content about Hattrick for years, and I know how hard it is to find the right answer. It's all out there, but scattered everywhere: the forum, HT-Press, external sites and forums.
Hattrick Codex was born to give every manager a point of reference: every concept explained as simply and directly as possible, so the game gets even better for all of us.
It doesn't replace the forum, which remains the heart of the game: it shines a light on it. Every figure links to its original source, often a thread you'd never have found without the Codex.
The studies aren't mine: they belong to the community that gathered and analysed them, and without them none of this would exist. Hattrick Codex preserves them and passes them on: it brings the knowledge of the most experienced managers together in one place and puts it in everyone's hands.
