What Data and Scale Does Untapped.gg Use for Its Stats and Tier Lists?

Untapped.gg builds its meta stats, tier lists, and deck data from millions of real matches recorded through its companion app. The site states that its tools are backed by more than 2 billion recorded matches, a player base of over 30 million, and over 15 million downloads. These figures are the basis for treating its stats and tier lists as aggregated, real-match data rather than editorial opinion — but they describe volume, not necessarily the recency or rank distribution of any specific dataset.

Where the numbers come from

Untapped.gg describes itself as a suite of tools for video games, with two connected parts:

• A companion app that tracks your matches and overlays your deck and stats on top of the game while you play.
• A website with meta stats, tier lists, and decks "powered by millions of real matches."

The match data feeding the web stats is therefore generated by players running the companion app, not by manual data entry or a small sample of curated games.

The published scale

These are the headline numbers on the site's landing page. They are useful as a rough credibility check: a dataset in the billions of matches is large enough that tier lists and meta stats can reflect broad play patterns rather than a handful of contributors.

What this means for reading the stats

Because the data comes from tracked matches, the stats and tier lists reflect what players actually played and how those games resolved. A few practical implications:

• Volume supports aggregation. With matches in the billions, archetype win rates and matchup tables can be built from many games per entry, which reduces the effect of single lucky or unlucky runs.
• The sample is self-selected. Only players who install and run the companion app contribute data. The site does not state here how it weights by rank, region, or patch, so treat tier lists as a broad signal rather than a precise prediction for your exact ladder position.
• Recency matters more than total size. A 20-billion-match total says nothing about how much of that data is from the current patch. Check the date or patch label on any specific tier list before acting on it.

How to verify a specific stat

1. Open the game you care about from the "Choose your game" entry point.
2. Go to the meta stats or tier list section for that game.
3. Look for the patch or date range attached to the list, and the sample size or match count behind an individual deck or matchup if shown.
4. Compare the archetype's win rate against its play rate — a high win rate on a rarely played deck is a weaker signal than one sustained across many matches.

If a tier list does not show a patch or date, treat it as directional only.

Bottom line

Untapped.gg's stats and tier lists rest on a large, real-match dataset: over 20 billion recorded matches from more than 30 million players and 15 million downloads, collected via its companion app and surfaced on the web as meta stats, tier lists, and decks. That scale makes the data credible for broad meta reading; the conditions that matter for any given decision are the patch, the rank bracket, and the sample size behind the specific entry you are looking at.
