Reading Lolumen's Hearthstone meta: what the numbers count
Which games the Hearthstone meta page counts, how small samples are marked, and how decks get their names, from the page and its methodology doc.
Lolumen's Hearthstone meta page shows class win rates, the most-played decks and a matchup grid, built from ranked games tracked on Lolumen. Before you lean on any of it, here's what the numbers count, what they leave out, and how decks get their names. Everything below comes from the page itself and its methodology doc, How the numbers work.
What's on the page
The meta page has a tab for each format: Standard, Wild and Twist. It covers the last 30 days and refreshes every thirty seconds while it's open. It's split into these sections:
- A headline naming the class that leads, with its win rate, its range and how many games it rests on.
- Most played: the most-played class, how many decks and players were found for it, and its most-played deck.
- Every class: each class's win rate, 95% range, share of ranked games and daily game counts.
- Featured decks: every deck with 20 or more games.
- Class against class: a matchup grid.
Which games count
The figures describe games tracked on Lolumen, not the whole ladder. The methodology doc is explicit that they "describe those games, not the whole ladder."
- Class win rates use ranked games tracked by the desktop app over the last 30 days, in the format you pick, from players who have agreed to Lolumen's terms.
- Casual, friendly and other non-ranked games aren't included, and neither are suspended accounts.
- Games added by hand count in the player's own stats but not in the community numbers.
- Every ranked game played with a known deck counts toward the deck meta. A deck is known if it's a saved deck, a pasted code, or a deck the desktop app saw queued.
Reading small samples
Every rate is shown with a 95% range next to it. Rates resting on fewer than 10 decided games are marked as early, but they aren't hidden: the doc says "Nothing is hidden for being thin." In the matchup grid, cells with fewer than 10 decided games are left uncoloured. Treat an early rate as a first look, not a verdict.
How decks are named
Decks are grouped by their cards, not by what players call them. Lists that share most of their cards are treated as the same deck. Each group is named after the cards it runs much more often than other decks of its class, so the name describes what makes the deck different. If two decks of a class would end up with the same name, the less-played one adds its next most distinctive card.
A deck's card list is an aggregate of everyone's lists, not any one player's deck. Its list and deck code appear only once 3 players run it. Until then, the page shows only the name, the numbers and the cards it's named for. No player is named on the page, and no deck's own name is read.
Matchups and Premium
Everyone sees each class's win rate and share. The methodology doc lists the full class-against-class matrix, and a deck's record against each class, as Premium features. For now, Lolumen's changelog says full Hearthstone insights are free for all accounts until the meta is built.
Keeping your games out
To leave your games out of the community numbers, turn off "Count my ranked games in the community stats" in Settings → Preferences. Your games then stay out of the class rates and the deck meta, but still count in your own analytics. To add your games, see the tracker. To look up any card in the decks, use the card library.
