Register, click on your profile, Steam Keys and there you have it.
3000 keys every 2 hours (1 hours 54 minutes as of now till next round)
Theres usually a few rounds like this judging by the giveaways they had in the past.
Hope all of you will get keys this time 
It’s solid, actually has fairly little to do with cleaning - it’s basically a nonviolent (well, on your part) stealth/action puzzle game. Worth the time
If anybody encountered problems with the giveaway its because alot of people overflooded the site when it started, now its fine, and they raised the key stock to 4000 from 3000 for each round.
Thanks. Worked just fine 
If anyone gets a white screen after clicking the get steam key button, you need to disable adblocker to get the captcha thing to appear.
Sounds familiar…
