Explore an all but forgotten 14th century Blackthorn Castle, surrounding dark forest and structures. Discover hidden passageways, clues and puzzles along the way! Uncle Henry has been hunting lost treasures for as long as you can remember. His legendary stories of adventure excited your imagination as you were a child growing up.

Player estimates
Nobody publishes how many people play The Mystery of Blackthorn Castle, so these figures are modelled from the public counts on App Store, Steam, 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 are the The Mystery of Blackthorn Castle 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.
