There are just 3 badly hidden giveaways in this post. All giveaways are region free (I hope so) and open for all level 1+ users (sure in that one). All giveaways will end on 20th of September.

Solve this Jigidi with 84 pieces to get a chance of winning Necrosmith (steam page, steamDB).

Solve this one to get a chance of winning In Other Waters (steam page, steamDB). Hint: letters are lowercased

Fix this one to get a chance of winning The Last Express Gold Edition (steam page, steamDB).

SOLUTION

Necrosmith: A popular strategy is to put the edges of the puzzle together first because, with one straight edge, the pieces are easier to identify and then "assemble" parts with distinctive features like, in this case, man/hummer/cat and then align them towards the edges.

Other Waters: When both presented images are overlapped you can see the code. It is called Visual cryptography. I draw code using online tool here.

The Last Express Gold Edition: You got a wrong code "iWuwe" and next to it instructions how to fix it "flip-W-u-is-i" instead of the game name in the link. So flipped W is M and u is i. So correct code is "uMiwe".

Thanks everyone for participating and bumping! Now you can go and enjoy solving easy puzzles here :)
