A few normally-paid Android games currently available for free on Google Play, though they all seem to still contain ads and/or microtransactions so I don’t know if the premium part is basically a scam. Comment if you can be bothered to investigate, I know I can’t!
A lot of those links are leading to Epic Freebie Games Radar but I was able to look them up and I downloaded a couple.
D’oh, I was trying to save the effort of using the share button instead of clicking through every single one to get the real link, I’ll hang my head in shame and fix the links properly, cheers!
