Estimates, not counts — nobody publishes real player numbers for mobile games, so these are modelled from public signals. How we work them out
Nobody publishes how many people play Black Book, so these figures are modelled from the public counts on App Store, Steam, Reddit, Twitch. 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.

How many people have rated, reviewed or installed Black Book where it is sold.
How many people gather around Black Book outside the stores — members, subscribers and live viewers.
Not tracked for Black Book: Google Play, Discord, YouTube. A platform appears here once the game has a link to it — most mobile games have no Steam port or subreddit, so a gap is normal rather than a sign the game is small.
A fusion of card-based RPGs and Adventure games, “Black Book” is a haunting tale of a young sorceress, who gave her life to serve the dark forces. Dive into the cold, yet alluring world of Russian folktales – and uncover the secrets that hide in the darkness. A young girl named Vasilisa, destined to become a witch, decides to throw her fate away and marry her beloved – but that dream is shattered when her betrothed dies under mysterious circumstances. Aching for her lost love, Vasilisa seeks out Black Book – a demonic artifact, said to be powerful enough to grant any wish to the one who uncovers all 7 of its seals. Join Vasilisa in her adventures across Russian countryside, as she solves the woes of common folk by confronting demons and performing exorcisms.
We estimate that about 3,700 people have played Black Book — plausibly between 1.7K and 18K. Around 180 of them play on a given day, in a range of 17 and 2.7K. Both figures are modelled from public counts on App Store, Steam, Reddit and Twitch rather than published by the developer, so read them as a scale rather than as a headcount.
Yes. Black Book 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.
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.
