About Hearthdle

Hearthdle is a fan-made daily game built on the cards of Hearthstone, Blizzard's digital card game. It went live in February 2026 and takes its idea from Wordle, LoLdle and Pedantix. It is not affiliated with Blizzard; card data comes from the official Hearthstone API and full artwork mostly from the Hearthstone Wiki, and new cards are added as they appear.

There are four modes, and each one draws a new card at midnight UTC. Cardle is the Wordle-like one: you type any card name and get a row comparing it with the day's card on type, set, class, rarity, mana cost, spell school or minion type, attack and health. Green is a match, orange is close, red is a miss, and arrows point to higher or lower values. Masked Name shows the day's card with its name erased and starts revealing the name letter by letter after a few misses; a side mode uses World of Warcraft spell icons. Card Art shows a small crop of a card's original artwork that zooms out after every wrong guess. Timeline gives you five cards to order from oldest to newest.

The guessing modes come in three pools: Classic, the cards from Hearthstone's first release; Standard, the core set and current sets; and Wild, every card from the past. Each pool has its own daily card, so a regular can play up to ten puzzles a day. Under each puzzle the site shows how many players found today's card and what yesterday's answer was, and the front page keeps a daily streak.

It suits Hearthstone players who know the card pool, from long-time Wild players to people who only play Standard. Progress is kept in the browser with no account and no tracking cookies, and the site is free, supported by donations.

How to play Hearthdle

1. Open hearthdle.com and pick a mode: Cardle, Masked Name, Card art or Timeline.
2. For the first three, pick a card pool: Classic, Standard or Wild.
3. Type a card name in the search box and pick it from the list.
4. In Cardle, read the tiles: green is a match, orange is close, red is a miss, and arrows show whether the answer's value is higher or lower.
5. In Masked Name and Card Art, use the extra letters or the wider crop each miss gives you until you name the card.
6. In Timeline, put the five cards in order from oldest to newest and submit.
7. Come back after midnight UTC for the next set of cards.

Tips

• Start Cardle with a neutral card of middling mana cost, so the class tile and the mana arrow both cut the list.
• In Standard, the set tile narrows the answer to a handful of recent expansions quickly.
• In Card Art, look at the colour palette and the creature type before the crop widens: art from the same expansion often shares a style.
• For Timeline, sort first by expansion era, then by the cards you remember being revealed together.
