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, Icon-ic spell, asks which World of Warcraft icon a spell's art comes from. Card Art shows a small crop of a card's original artwork that zooms out after every wrong guess, with a Signature pool for the cards' signature art. 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 with the two side pools and Timeline a regular can play up to twelve 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.
