Hey bud, I expanded on another fella's guide over on the forums, but I don't know if that's still locked, so I'll paste the instructions here.
A note to all Canadians:
You will not be able to log in via the Windows 10 app, so don't even try.
You also won't be able to install the Android app from the Google Play Store at https://play.google.com/store/apps/details?id=co.uk.game.mobileapp
If you're uncomfortable installing APKs on your phone, leave now or forever hold your peace
To expand upon what @TheWriterOfVazq wrote:
1) Register at https://user.gamewallet.co.uk/ using your Steam account
2) You will be redirected to create a GAME Wallet account. Using a Canadian or US address won't work (even though they list these countries in the drop down, the turds) so use the following tools to find a legitimate UK address:
2.1) Use http://www.fakeaddressgenerator.com/World/uk_address_generator to find a valid street.
2.2) Import the street into http://www.postoffice.co.uk/postcode-finder to find the actual city and postal code. If you can't find it, go back to Step 2.1 and generate again.
2.3) Go to http://whitefiles.org/b4_g/5_towns_to_counties_index/ and Ctrl+F to find which county corresponds to the city (city name is on the left, county is on the right)
2.4) Complete your registration, using an actual email. Don't worry about the phone or alerts.
3) Register at http://www.game.co.uk/ using your multiple-digit numerical code shown in the GAME Wallet Settings > Reward Account page to auto-link your account and fill in info for you.
4) Download and install the GAME app from your Android device at https://apkpure.com/game-reward-mobile-app/co.uk.game.mobileapp
5) Log into the app at the top right using your Steam account. Once logged in, check "Your Wallet" and ensure you can see the code from Step 3.
6) On the app's main page (star at bottom left), scroll down until you see Fractured Space. Scroll right to "Win Exclusive Signed Art", click the purple entry button inside, and add a notification.
7) Pray to your gods that this will actually work. Hopefully some innocent chap in the UK doesn't receive a signed poster, and hopefully you get a nice Brawler skin.
Your searching is pretty weak https://play.google.com/store/apps/details?id=co.uk.game.mobileapp I got that by typing game.co.uk
