Changelog | PuzzledQuant

September 2026

New Features

Fermi Estimation — A new game for the estimation round. You are asked for a quantity nobody expects you to know exactly — the number of trees on Earth, the mass of the atmosphere, the legal chess positions — and answer with a range rather than a number. A range that contains the answer scores on how narrow it is, so a lazy "one to a trillion" is worth nothing, and a range that misses loses points in proportion to how far off it was. Ten questions per run across three difficulties, with time left on the clock worth a small bonus. Available on premium.
A Much Bigger MCP Toolkit — Your assistant can now do most of what the website does. It can search and browse problems instead of drawing one at a time, open a specific problem you name or link, pull today's Question of the Day, read the official written solution when you ask for it, suggest what to practise next based on the topics you have covered least, find problems similar to one you just solved, bookmark problems and file them into your problem sets, and tell you your leaderboard rank. It can also look up the real topic, company, and job filter values, so asking for "Jane Street probability problems" or "quant roles in Singapore" no longer quietly comes back empty.
Custom Problem Sets — Organise problems into named sets for revision, interview prep, topic practice, or any other workflow — "Interview shortlist", "Probability drills", "Weekend practice", or whatever suits you. Create and manage sets from the problems page, select one to see only its problems, and add or remove a problem straight from its page with the "Add to" button, which remembers the set you used last for one-click filing. A problem can live in as many sets as you like. Available on premium.

Improvements

Dice Market Maker Now Lets You Make the Market — The game finally does what its name says. In the new Make mode you publish your own bid and ask on the hidden dice, and two kinds of counterparty trade against it: noise flow that pays you the distance from fair value but walks away from a market that is too wide, and informed flow that already knows where the dice land and only trades the side you priced wrong. Fills stop at a position limit, and each round shows which of your trades were adverse. The original Take mode is still there behind a toggle, and the two modes rank on separate leaderboards.
Redesigned Discussion Composer — Creating or editing a discussion now reads as one form instead of a stack of mismatched boxes. Every field carries a label and a line of guidance, the title has a live character count and the tag picker a count of the five you are allowed, and the anonymity option sits at the bottom with an explanation of what it does rather than floating above the title. The image dropzone tells you the accepted formats and size, shows a preview you can remove, and the whole form — dropzone, tag menu and all — finally follows the app's dark mode.

August 2026

New Features

QR Device Sign-In — When you're signed in on one device, scanning the launch banner's QR code now signs your phone into your account instead of just opening the site. You're asked to confirm on the signed-in device before anything is approved.
Installable Mobile App — Install PuzzledQuant from your browser for a standalone home-screen experience on Android, iPhone, iPad, and desktop. The app now includes offline recovery and optional device Push notifications for replies, reactions, and achievements.
Individual Resume Pages — Resumes now have their own dedicated pages with descriptive URLs, breadcrumb navigation, and search-engine-friendly metadata. Clicking a resume card navigates to its page instead of opening a modal, making each resume discoverable by search engines.
Connect PuzzledQuant to Any MCP Client — PuzzledQuant's MCP server now works beyond ChatGPT. Claude, Cursor, VS Code, and any other client that speaks the Model Context Protocol can connect to https://puzzledquant.com/mcp and practice problems, check progress, and search quant jobs from inside your assistant.
Authorization Consent Screen — Connecting an application now shows you exactly which app is asking, where it will send you back, and what it will be able to do, before anything is approved.
Exercise Progress Tracking — Your progress on OCaml and C++ coding exercises is now tracked automatically. See solved, attempted, and seen-solution status on exercise list pages, with progress summaries on the Resources page and in your profile's Activity section.
Progress Bars on Resource Cards — Course and exercise cards on the Resources page now show progress bars below the description, giving you a quick visual overview of your learning progress.
C++ Programming Exercises — A new collection of 10 interactive C++ exercises covering systems programming, concurrency, and low-latency patterns relevant to HFT engineering. Includes unique pointer, lock-free SPSC queue, memory pool allocator, LRU cache, thread-safe singleton, custom vector, order book, ring buffer, and type-erasure patterns.
10 More C++ Exercises — The C++ collection now has 20 problems. The new ones cover shared pointer with weak references, small string optimization, intrusive linked lists, compile-time type lists, cache-friendly Eytzinger binary search, thread pools, reader-writer locks, market data conflation, feed sequence gap detection, and binary wire protocol decoding.

Improvements

Brar Finance Launch Banner — The launch navbar now highlights Brar Finance and links to its daily Wall Street newsletter subscription.
Enhanced SEO for Games & Exercises — C++ and OCaml exercise pages and all game pages now have richer metadata including keywords, Open Graph, Twitter cards, and canonical URLs for better search visibility.
Clearer Subscription Cancellation Status — Billing history now explains whether a cancelled subscription remains active until the end of its paid billing cycle or ended immediately because no payment was charged.
Exercise "Attempted" Status — Opening an exercise now marks it as "Attempted" with a clock icon and "Finish it" label in the exercise list, giving you a clear signal to pick up where you left off.
Mobile QR Handoff — The launch banner now lets you scan a QR code to open PuzzledQuant directly on your phone.
Redesigned Exercise Workspace — C++ and OCaml exercise pages are now a full-height workspace: the code editor fits the screen and scrolls internally instead of stretching to the length of the file, and the problem and code panes can be dragged to any split you like (your layout is remembered). A collapsible console at the bottom of the editor collects both Run output and Submit feedback in two tabs, the editor toolbar gained reset and copy actions plus ⌘/Ctrl+Enter to run, and narrow screens get a Problem/Code switcher instead of two cramped columns.
Rebuilt Notifications — Notifications have been rebuilt end-to-end for a more reliable experience.
Leaderboard Difficulty Badges — Leaderboard entries now display difficulty badges for quick reference.
Compact Mobile Banners — Launch and premium announcement banners are now more compact on mobile, keeping the experience clean.
Updated Pricing — Premium and newsletter pricing have been refreshed.
Your Rank, Always Visible — Logged-in users now see their own leaderboard entry pinned at the top, so your rank is always in sight.
Breadcrumbs in Resources & Games — Breadcrumb navigation is now consistent across all resource detail pages, games listing, and individual game pages, making it easy to navigate back from any resource or game.
Centered Sign-In Prompts — Sign-in and premium access prompts on course, exercise, and curated-list pages are now better centered vertically on screen, with responsive positioning for both desktop and mobile.
Dark Mode — Dark theme is now available across the entire platform, from problem statements and discussions to job descriptions and profile pages. Toggle it from the navbar — it follows your system preference by default. Feedback is appreciated!

Bug Fixes

Fixed navbar logout to consistently redirect to the home page.
Fixed the Problems Conquered card using a neutral border in dark mode instead of a teal accent.
Fixed profile-menu links to smoothly scroll to the My Progress and My Bookmarks heading after filtering the problem list.
Fixed the institutional page logo not switching to the dark variant when dark mode was toggled.
Fixed profile pages overflowing the screen on mobile, including a fitted tab bar and responsive billing history.
Preserved customer-provided cancellation reasons when payment-provider webhooks arrive or are retried.
Fixed an issue where the forgot password link had inconsistent spacing.
Fixed coupon pricing to correctly reflect the selected currency.
