CortiX Games is an independent, learner-built training platform. It is not affiliated with, endorsed by, or sponsored by any trading firm, publisher, university, or competition organiser.
Any firm names that appear in interview-context notes are used purely descriptively to indicate the kinds of role a topic is relevant to; no commercial relationship is implied.
Practice questions are drawn from a mix of (a) original questions authored for the platform, (b) classical probability and combinatorics problems that have entered the public puzzle tradition, and (c) prompts adapted and rewritten from openly available problem-solving literature. Where a question reflects a technique discussed in a published textbook or competition, only the technique itself is reused; numbers, narrative, and presentation are independently produced.
If you believe a specific question reproduces protected expression from a work you own, please contact cortixgames@gmail.com and we will review and rewrite or remove it promptly.
The site bundles KaTeX (MIT, github.com/KaTeX/KaTeX) and Chart.js (MIT, chartjs.org). KaTeX math fonts are distributed under SIL OFL 1.1. Observable Plot and D3 (used on chart-bearing tutorials) are loaded under their respective ISC / BSD-3 licences.
All firm names referenced in question or tutorial context (e.g. trading firms named on a concept page's interview-context callout) are the trademarks of their respective owners. Such references are descriptive and do not imply sponsorship or endorsement.
