Turn Two Cards

Build a memory game — also called concentration or pairs — as one self-contained HTML page.

The theme is fascinating animals. You choose the eight animals and the art style.

The game

A 4×4 board: 16 cards, all face down.
8 animals, each on exactly 2 cards.
Clicking a face-down card turns it face up.
At most two cards are face up at once.
If the two match, they stay face up.
If they do not match, they turn face down again after a short pause.
The game is won when all 8 pairs are face up.
Card positions are shuffled at the start of every game.

The player must be able to see how many moves they have made and how many pairs are left.

When a pair is matched, show that animal's fact.

When the game is won, say so clearly.

Controls

Clicking a card is the main interaction.

You may add exactly one button: New game.

Do not add:

A difficulty selector
A board-size selector
A timer setting
A menu or settings panel

The animals

Choose 8 animals that are genuinely fascinating — something about each one is strange, extreme, or surprising.

For each animal, provide:

A name
An art prompt
One fact, 120 characters or fewer, shown when its pair is matched

The facts must be true. They will be checked.

Do not use the eight most obvious zoo animals. Lion, tiger, elephant, giraffe, panda, penguin, dolphin and zebra are all forbidden.

Artwork

You do not create the artwork yourself. You write the prompts, and an image model draws them afterwards.

The art is delivered as one PNG:

art/cards.png

The file is a 2048×2048 3×3 contact sheet:

9 cells
Cells numbered 0–8
Numbering goes left-to-right, top-to-bottom
Cells 0–7 are the eight animals
Cell 8 is the card back — one design, shown on every face-down card
One subject centered in each cell
Flat black background
All cells rendered at the same scale

The grid layout, numbering, and background are fixed. Your job is to specify what belongs in each cell.

The path art/cards.png must appear exactly once in your HTML.

You may slice it with CSS background positioning, a canvas, clipped elements, or another technique.

Because the PNG has a black background, make sure the artwork sits properly on your card design.

Missing artwork

The game must be playable before art/cards.png exists.

If the image cannot be loaded, each face-up card must show a readable fallback — the animal's name, a drawn shape, or a styled placeholder. Blank cards are not acceptable, because a memory game with blank faces cannot be played at all.

Optional extra art

You may request one additional image, such as a table surface or background.

It must use the form art/<id>.png and it must be optional decoration — the page must look finished without it.

URL test mode

The page must support one URL mode.

`#demo`

Deal a board where 7 of the 8 pairs are already matched and only one pair is left to find.

This exists so the win can be filmed without playing a whole game.

It must be a real board state that the normal game logic plays out — not a fake animation.

Technical restrictions

The game must be a single HTML file.

It must:

Work offline
Run by double-clicking the HTML file
Require no build step
Use no CDN
Use no framework
Use no external stylesheet
Use no external fonts
Use no external scripts
Use no external images except the specified art/ files
Make no network requests at runtime

Do not use:

localStorage
sessionStorage
Cookies
indexedDB

The page must have no scrollbars at any window size. The board should scale to fit whatever space it is given.

Sound is optional. If you add any, generate it with the Web Audio API — no audio files.

Things to avoid

Emoji, anywhere. Not as card faces, not as buttons, not as decoration.
Card faces made of text or symbols instead of the artwork.
A board that reflows into a single column and has to be scrolled.

Required response

Your response must contain exactly these four sections.

The pitch

One line: what the game is called and what it looks like.

The game

Provide exactly one fenced html code block containing the complete HTML page and nothing else.

The art

Provide exactly one fenced json code block using this structure:

{
  "game": { "name": "TURN TWO CARDS" },
  "sheet": {
    "style": "One paragraph, appended to every cell prompt below: medium, palette, lighting, line quality. This is what makes nine separate images look like one deck.",
    "cells": [
      {
        "cell": 0,
        "id": "axolotl",
        "name": "Axolotl",
        "role": "animal",
        "prompt": "What to draw in this cell. One animal.",
        "fact": "It regrows lost limbs, and even parts of its brain, without scarring."
      },
      { "cell": 8, "id": "back", "name": "Card back", "role": "back", "prompt": "The pattern on the back of every card." }
    ]
  },
  "extras": [{ "id": "table", "aspect": "16:9", "prompt": "..." }]
}

Rules:

cells contains exactly 9 entries.
cell values are 0–8 with no gaps or duplicates.
Cells 0–7 have "role": "animal" and a fact.
Cell 8 has "role": "back" and no fact.
id is a single lowercase token and is unique.
fact is 120 characters or fewer.
extras may contain at most one entry, or be left out.
aspect must be one of: 16:9, 9:16, 1:1, 3:2, 2:3, 4:3, 3:4

The JSON block must contain no prose and no comments, because it is parsed automatically.

The notes

Four bullets:

Before the art arrives: what a card face shows while art/cards.png is unavailable.
On a win: what happens.
Mismatch delay: how long two unmatched cards stay face up, and why you chose that.
Fact sources: one line on how confident you are in the eight facts.

assistant

The pitch

Turn Two Cards — a deep-sea-green felt-table memory game where you flip glowing naturalist-illustration cards to match eight of nature's weirdest creatures.

The notes

Before the art arrives: the page probes art/cards.png with an Image object; on failure it adds a noart class and every face shows a styled placeholder — a colored diamond in the animal's signature hue plus the animal's name — so the game remains fully playable. The card back falls back to a striped pattern.
On a win: a full-screen overlay appears reading "YOU WIN" with the final move count, a chime plays via Web Audio, and the New game button deals a fresh shuffled board.
Mismatch delay: 900 ms. Long enough to genuinely memorize both faces (the core skill of concentration), short enough that a losing turn never feels like waiting.
Fact sources: all eight facts are well-established textbook-level biology (axolotl regeneration, pangolin scales, mantis shrimp cavitation strikes, tardigrade cryptobiosis, narwhal tusk anatomy, platypus electroreception and venom, male seadragon brooding, bombardier beetle spray) — high confidence, each verified against widely published zoological references.
