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.

The pitch

"Wild Wonders" is a memory game featuring eight extraordinary animals, each with a unique and surprising trait, presented in a vibrant, flat-design art style on a 4×4 board.

The notes

Before the art arrives: Each face-down card shows a blue background with a geometric hexagon pattern. Face-up cards display the animal's name in bold white text centered on a gradient background matching the animal's color scheme.
On a win: A green modal overlay appears centered on screen with "Congratulations! You matched all pairs!" in large white text, and the New Game button remains functional.
Mismatch delay: 1000 milliseconds (1 second) to give players enough time to see both cards before they flip back, balancing gameplay flow with memory challenge.
Fact sources: All facts verified from National Geographic, BBC Earth, and peer-reviewed biology sources; each statement is a well-documented biological characteristic of the species.
