Player estimates
Nobody publishes how many people play O2Jam, so these figures are modelled from the public counts on Google Play, App Store. Each count stands in a roughly known ratio to a population — one Play rating per ~45 players, one Steam review per ~35 owners — and the estimates below combine those readings, weighted by how much each source can be trusted to speak for the whole game. Read the range as the answer and the headline as its middle.
Estimated daily players
~130
0.0% no change vs one week agoRange 13 – 770
No source reports a live count for this game, so this is a share of the total player base — a genre assumption rather than an observation, which is why the range is wide.

Store signals
How many people have rated, reviewed or installed O2Jam where it is sold.

Frequently asked questions
How many people play O2Jam?
We estimate that about 2,600 people have played O2Jam — plausibly between 1.3K and 5.2K. Around 130 of them play on a given day, in a range of 13 and 770. Both figures are modelled from public counts on Google Play and App Store rather than published by the developer, so read them as a scale rather than as a headcount.
Is O2Jam still active?
Yes. O2Jam is holding steady — it measured within a percent of where it was a week ago. We recheck every source daily, and the charts on this page show each platform's readings over time.
How are the O2Jam player estimates worked out?
Nobody publishes player counts for mobile games, so we infer them. Each public count we can read is converted into a population using a documented ratio — roughly one Google Play rating per 45 people who played, one Steam review per 35 owners, one Discord member per 40 players — and the live counts (Steam concurrents, members online, Twitch viewers) are converted the same way into a daily figure. Those separate estimates are then averaged in proportion to how much each source can be trusted, which is why sources that disagree widen the published range instead of cancelling out. This page is built on 2 readings taken since August 8, 2026.

O2Jam was released on June 27, 2019 for Android and iOS.
