"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.

Fun and challenging


This game is fun, and surprisingly challenging. The cute creatures and the hunt for them just to take photos is innocent and enjoyable. The navigation is really hard to do in the timeframe if you want a perfect score of 3 stars, and I feel that getting them really tests your orientation skill and is extremely satisfying when you nail it! I like that the boat really handles like a boat in the game, although I missed the initial introduction to the game controls and had to actually Google how to speed up because it wasn’t repeated anywhere in the game menu (my first reason why it lost a star). About the controls: I’m used to controlling my phone with two thumbs (resting it upright on my pinky fingers or palms) so it isn’t hard for me to play this game, but I can see how this wouldn’t be so fun for an older generation, unless played seated at a desk perhaps with an iPad. As a scientific endeavour they lost another star from me because of the limited gender boxes at the start of personal information (you can only choose male or female) and I was frustrated that they completely lacked other gender options, or “rather not say”. It is unhelpful and misleading to ask for data about mental health and then use outdated gender profiling methods. Overall this is a noble, 5 star idea and quite well-executed with some room for improvement. I’d love to see this on console platforms too!

Good idea, but doesn’t work properly


The idea is great, however, the game doesn’t work properly. The controls are very “iffy.” They worked for a while, but then were totally unresponsive. I thought perhaps my screen was too dirty or had too much grease from my finger to cause the controls to stop working, so I cleaned the screen, but that didn’t help. Then tried a stylus, which worked better, but the game just keeps getting stuck. I swipe left to avoid ice, but the boat doesn’t go left, I swipe right to avoid ice, but the boat doesn’t go right. I go around a buoy, and then try to go to the next buoy, but the boat refuses to move. The arrow keeps popping up indicating to push upward, but the screen is totally unresponsive. Every round this happened on, I got 1 star for being too slow, but I was too slow because the boat would not move. The controls need to be adjusted so they work properly, or I don’t think this will be very helpful in collecting the correct data. If people are getting “bad scores” because the controls don’t work, that really defeats the purpose. There needs to be a better explanation of how the gestures work, because the iPhone X screens have different sensitivities than an iPhone 6. I don’t know if I should be pressing harder or lighter to make the controls work.

Fun with a purpose!


This is a fun first-person navigation game where you maneuver a boat through obstacle courses. Playing it provides real world data that’s currently being collected for dementia research. They provide information on boat controls, but it is a little confusing when you start playing so here’s my take on it to help with the learning curve.

Even if you are ambidextrous, don’t use both hands. Just use one hand (one finger really) for all controls. Tap left, right, or center to steer in those directions while moving. Swipe up to accelerate, and swipe down to stop. Combine swiping with steering for good control. For example, to accelerate forward swipe up in the center of your screen or to accelerate while turning left swipe up on the left side of your screen.

For photo challenges, you don’t need to accelerate. Just tap left or right to dodge. To take a picture, just be patient. Wait until all three stars are lit before you take your picture. That part’s not a speed challenge.
