"It’s not just a game, it’s a quest to help scientists fight dementia!”

It sounds too good to be true but this really is a game, where simply by having loads of fun chasing creatures around magical seas and swamps, you can help to fight a disease that currently affects 45 million people worldwide.

In fact playing SEA HERO QUEST for just 2 minutes will generate the equivalent of 5 hours of lab-based research data.

Created by GLITCHERS, presented by Deutsche Telekom and supported by scientists from University College London and University of East Anglia and the lovely people at Alzheimer’s Research, SEA HERO QUEST is an epic culmination of science and gameplay that will change the way dementia research is done forever.

One of the first symptoms of dementia is loss of navigational skills. Doctors cannot differentiate between getting lost caused by disease and getting lost caused by natural ageing because a benchmark of “normal” does not exist.

Until now … because as you play, your navigational data is tracked anonymously, stored securely and combined with every other player from around the globe, to create the world’s largest crowd sourced data set benchmarking human spatial navigation. This incredible resource will eventually lead to the development of new diagnosis tools and treatments for dementia.

Navigate Arctic Rivers, Golden Shores, Mystic Marshes, Kano Reefs and High Roller storms, collect memories in your journal and chase magical creatures like Adorabella, Galleo and Octopoid. Collect as many starfish as possible and use them to customise your boat with a new lick of paint, a host of flags and much more!

Deutsche Telekom believes that life is for sharing, that’s why they are presenting SEA HERO QUEST – a game to help scientists fight dementia and work towards a future where memories are shared not lost before their time.

Join the Quest and be a real-life hero.

Sea Hero Quest does not access, store or submit any HealthKit related data. Sea Hero Quest uses ResearchKit to ask optional scientific questions for further helping the research.

Love the idea of contributing.


Dementia is a huge problem and with the heavy carb diet that the world now consumes is set to become an even greater problem in the future. If playing this game contributes to any way to helping unlock the solution I am pleased to be a part of it. It’s also fun to play and quick short levels means if you only have a minute you can still “find the time” to help out. What are you waiting for!

But I don’t fit


This app is a great research tool, but at the first level I’ve run across some issues. I don’t fit some of the boxes that the research data is looking for, & there is no way for me to point out that there’s no box for me. Beyond my game stats, I can either give incorrect data or none at all.
That’s a bit rubbish.
Either give “other” options for false binary questions, or give people a way to skip questions they cannot answer correctly, thanks to the format.

Great app, for science.


Boost took me a bit to get right... it’s not shown that well. I have found it to be a flick up from the bottom of the boat. I like the short levels and some of them have made me think about my own reaction.
