Where Transformice sits on the grid
Compare the whole catalogueTransformice plotted on the axes the GamingPickz Score is built from, on the full 0 to 100 scale so its position is its real one. Change either axis to see where it lands.
1 games have both
Players. The share of Steam reviews marked positive, pulled toward the catalogue average in proportion to how few reviews stand behind it. A game with 200 reviews moves a long way toward the average; one with 200,000 barely moves at all. Without this a title sitting at 100 percent on nine reviews outranks Half-Life 2 at 98 percent on 278,000.
Popularity. A blend of two things that are not the same. Audience is how many people wrote a Steam review, which is a floor on how many played it. Reach is how many language editions of Wikipedia document the game, which is cultural footprint rather than sales. A game can score high on one and low on the other: a huge free-to-play title has audience without reach, and a landmark console exclusive has reach without a Steam audience at all. Where both exist they are averaged; where only one does, that one carries it.

Every point links to that game's entry. The value map and the reception map are fixed views of the same data.
How positions are decided
No paid placement, no favouritism, live third-party data
- Placed by the published method, not by us. Every coordinate is computed from the axis definitions and weights printed on this site. Nobody moves a point. See the axes.
- Nothing here is paid for. No sponsored placements, no promoted slots, no arrangement of any kind affects a position. If that ever changes it will be labelled and sit outside the ranking.
- No favouritism, including our own. The 16 games we have written full reviews of are scored by exactly the same formula as the other 1,510, from the same third-party inputs, and they land where it puts them. Our own opinion of a game does not enter its coordinates.
- A position is not an endorsement. It says how a game was received and what it costs, not that we recommend it. Where we do recommend something, it carries a written review with a name on it.
- Fetched from live third-party data. Player sentiment from Steam, critic aggregates as published on store pages, prices checked hourly, attention from Wikipedia. Each figure carries its source and the date it was read, and we do not adjust any of them.
Is Transformice still active? Players right now
Transformice has a modest but active community: 1,284 people were playing at once when we last read Steam on 19 October 2026. This is a snapshot, not a live counter, and it is a recent concurrent reading rather than an all-time record. For what is trending across the catalogue right now, see the pulse.
How many people own Transformice
This is an estimate, not a sales figure, and the two are not interchangeable. SteamSpy samples public profiles and publishes a range; the range here spans a factor of 2.5, and that width is the honest part of it. We show both ends rather than a midpoint, because a midpoint would look like a measurement.
Steam only. Console and storefront sales are not counted, so a game that sold heavily elsewhere reads low here. Read on 19 October 2026. Where a publisher has announced a real unit figure, that appears separately and carries its source.
Transformice price & deals: is it on sale?
We have one reading so far: Free on 30 August 2026. Prices are checked daily from here, and this becomes a chart once there is more than one point to join. A single observation is a price, not a history.
What readers say about Transformice
Reviews written by people who have played it. These are separate from the GamingPickz Score and are never averaged into it: that score comes from thousands of Steam reviews with a sample-size correction, and a handful of unverified ratings would distort it rather than improve it.
