the Counter
Everything on this site is free and stays free — no ads, no sign-ups, nothing behind a wall. What is on the counter is the same work packaged to take away: single files that run straight from disk with the wifi off. Take one title, one wing, or the lot. Buy nothing and you lose nothing.
A wing at a time, if the whole site is more than you want. Every pack below is already inside the Complete Collection.

The Complete Collection
Everything, once, for good — all 126 titles across the arcade, the Quantum Lab, the Sacred wing, the App Shelf and the University, plus the archived builds, the whole puzzle vault as raw data and the courses set for paper. Every pack below is inside it. Future titles are included as they are built, so this is bought once rather than subscribed to. Delivered as one folder that runs straight from disk with nothing installed and no connection needed.

Normal Games Pack
All 35 games from the Game Room in one folder — Rummy, Sudoku, Solitaire, Hearts, Spades, Canasta, Mahjong, Tetris, Scrabble, the sort puzzles and the rest. Each is the same single self-contained file the site serves, so every mode, rule set, puzzle bank and AI opponent comes with it and none of it phones home.

Quantum Lab Pack
All 40 experiments from the Quantum wing — superposition, entanglement and measurement worked through games rather than equations, from quantum poker and bridge to the sliding puzzle and the harmonic tables. The whole lab, offline, in the state the site runs it.

University Pack
All 26 courses as they run on the site — algebra, pre-calculus, the four calculus courses, linear algebra, physics, chemistry, psychology, the Python sequence and the Spanish ladder from 101 to 301. Interactive, with the worked examples, practice sets and full solutions intact, and none of it needs a connection once it is on your machine.

Course Readers
The University wing set in type and bound for paper — every subject as a printable PDF, exercises numbered so a printed copy and the page on screen still agree. One file per subject. Reading, not clicking.

Puzzle Pack Vault
Fifteen packs of generated positions — roughly fifty-five thousand puzzles across tangram, hexomino, katamino, polyhex, the ancient Sei Shōnagon dissections, curio and dissect. Every board machine-checked against a reference solver and shipped with its solution and its par, so the stars mean something. Raw JSON in the schema the games read, which makes it as useful for building your own solver as for playing through.

Sacred Geometry Pack
All 12 studies from the Sacred wing — the Flower of Life, the golden ratio, quasi-primes, recursive polyforms and the harmonic series, each one something to turn over rather than win.

App Shelf Pack
Both tools from the App Shelf — the scientific calculator with a hundred keypad layouts and its six workbenches behind the keys, and the loan cost calculator built around the Icelandic verðtryggt lán. Nothing is fetched at run time, so they work on a plane, in an exam room with the wifi off, or from a memory stick.

Archive Pack
The 11 superseded builds, kept because they are not the same game twice — earlier rules, earlier interfaces, the arcade as it was before the rewrites. For anyone who liked the old one better.

Support the Site
Not a product. cardspuzzle has no ads, no sign-ups, no tracking beyond a visitor count, and nothing behind a wall — it is one person building things and putting them up. If something here saved you an afternoon or taught you a chapter, this is the place to say so. Nothing is unlocked in return, because nothing is locked.

Checkout is not connected yet
Nothing here can be bought at the moment — the items are listed so the shape of the place is visible, but no payment provider is wired in. Iceland is not one of the countries where Stripe will open a merchant account, so the checkout has to come from a merchant-of-record provider that pays out to an Icelandic bank or a PayPal account: Paddle, Lemon Squeezy, Payhip or Ko-fi are the realistic ones. They act as the legal seller, which also means they collect and remit VSK and EU VAT rather than leaving it here.
To turn an item on, open catalog.json, find it under
sections.store.entries, and set two fields:
- put the provider's checkout URL in
buy - change
statusfromsoontolive
Then run python prerender.py && python intro.py && python seo.py
and mirror catalog.json into catalog.js. The row grows a
Buy button and the front-door tally follows on its own. Prices live in
price and are plain text, so they can read
2.900 kr. or pay what you like equally well.
