Rumble Club - Free Game of the Week Bonus (Requires base game to redeem)
I have just tried to get Freshly Frosted and got stuck behind one of the most bizarre captcha tests I’ve ever seen…
No CAPTCHA for me, just clicked the link, clicked to add it, confirmed it, and done.
It sounds like I might have missed out on another free game in not getting the CAPTCHA.
Today on GOG:
Islands of Insight is a puzzle game on steam that’s free to keep temporarily.
Today on Epic:
On my Steam at least it shows that it’s 50% off (both standard and deluxe editions) until July 11. The only free thing is the demo.
I grabbed it free and it is in my library. Must have passed or was a mistake. I own it now, though, fully.
Just Googled “islands of insight free” and yesterday it was free to keep for 24 hours.
It ended at 10 AM PST this morning.

On giveaway at GOG:
Cakey’s Twisted Bakery is a new game that just launched and is free for the next two days (says offer ends 7am CST on the 7th)
If you have Amazon Prime, they just put up a bunch of new free games.
Epic: Card Shark, Deceive Inc
GOG: Hitman Absolution, Call of Juarez, Soulstice, Star Wars II: Battlefront, Forager, Call of Juarez: Bound in Blood.
Plus some games that activate via Amazon Prime Gaming and who does that?
Wow! Hitman is a very good game (assuming you like the genre). There’s actually a lot more to it than just that one game and they all tie together narratively but, for free, this one is certainly worth a try. If you like it you can get lots more (at a cost). Better, it is possible to link them all together so they all play like one game (massive game).
ETA: Deceive Inc is also pretty cool if it is the game I think it is (I didn’t check).
Today on Epic:
I got Floppy Knights too.
That was last week’s. You might have caught it before the change over to this week’s game.
Newly released on Steam. Looks like it’s permanent free play.
Once Human is a multiplayer open-world survival game set in a strange, post-apocalyptic future. Unite with friends to fight monstrous enemies, uncover secret plots, compete for resources, and build your own territory. Once, you were merely human. Now, you have the power to remake the world.
Some of the reviews suggest the game might be installing spyware on your machine, FYI.
