ScryGuess: Can you guess my Scryfall search of the week? Try to be as quick as possible!

This is a tiny web game for Magic: The Gathering fans, powered by the Scryfall API. Play alone, or challenge your friends!

TODO: soon I'll try to publish this game as an app on the Google Play Store!

How to play?

• Click the "Generate a random card" button to reveal a random Magic card matching a secret Scryfall search.
• Try to guess the search criteria based on the cards you see.
• You can switch between English and French using the language toggle at the bottom.
• When you're ready, reveal the solution to see if you guessed correctly (at the end of the page)!

✨ Cool features!

• Random card generation from a hidden Scryfall search, updated every week (if I think about it).
• Bilingual interface with a button to swap languages (English 🇬🇧 and French 🇫🇷).
• Responsive and simple design.
• Not affiliated with Scryfall or Wizards of the Coast — just for fun!

🔧 How to change the weekly Scryfall query?

If you'd like to change the Scryfall search used by the game (for example to set a new "search of the week"), simply edit the JavaScript constant in index.html:

• Open index.html and look for the JS configuration section. Find the constant SCRYFALL_SEARCH_QUERY (current example: t=cleric id=boros game=paper).
• Replace the string with the Scryfall query you want to use. The script will URL-encode the query automatically.

Example, to search for green 2/2 bear creatures with converted mana cost 2:

// in index.html
const SCRYFALL_SEARCH_QUERY = 't=creature t=bear color=green cmc=2 power=2 toughness=2';

Notes:

• Use the Scryfall search syntax, to build advanced filters.
• The configuration is client-side: anyone viewing the page source can read the query. If you want to keep the query truly secret, do not publish it in index.html (or remove the <details> "Solution" block that reveals the search explicitly).
• The script automatically appends unique=cards&as=grid&order=name and performs URL-encoding, so only provide the q= part in plain text.

Enjoy the challenge, and see how quickly you can deduce the weekly query I used!

How to use the "random mode"?

I'm working on a different mode of this game, where it could be used without the need of a manual modification every week or so. It's a prototype right now, but you can test it!

In the new "random mode": the request is randomly generated by a JavaScript code, with a new request every time the page is reloaded and displayed on your device.
