Sea Hero Quest
Sea Hero Quest is a mobile game which contributes to research on dementia. It was designed by British game company Glitchers in 2016 in association with Alzheimer's Research UK, University College London and the University of East Anglia and with funding from Deutsche Telekom. The idea for the game came from neuroscientist Michael Hornberger of the University of East Anglia who collaborated with Hugo Spiers of University College London and a group of six other neuroscientist. The way in which players navigate the game will help researchers to understand the mental process of 3D navigation, which is one of the first skills lost in dementia. It is hoped that a large number of people will play the game, thus contributing much more data than could easily be obtained in a laboratory experiment. The plot of the game involves a sea journey taken by a son in a quest to recover the memories his father has lost to dementia. There are three sections: navigation, shooting flares to test orientation, and chasing creatures. Each has been "carefully crafted to be as fun and exciting as it is scientifically valid"

Player estimates
Nobody publishes how many people play Sea Hero Quest, so these figures are modelled from the public counts on Discord, 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.

Not tracked for Sea Hero Quest: Google Play, App Store, Steam, Reddit, 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.
Storyline
Sea Hero Quest explores the story of a father and son who have spent years exploring the seas and sketching memories into a journal. When the aging father accidentally drops the sketchbook into the sea, the son sets out to rebuild the journal and help his father remember the vibrant years they shared.

Frequently asked questions
How many people play Sea Hero Quest?
We estimate that about 7,000 people have played Sea Hero Quest — plausibly between 2.6K and 18K. Around 130 of them play on a given day, in a range of 40 and 350. Both figures are modelled from public counts on Discord and Twitch rather than published by the developer, so read them as a scale rather than as a headcount.
Is Sea Hero Quest still active?
Yes. Sea Hero Quest 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 Sea Hero Quest 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 1 readings taken since August 9, 2026.
