Buried Treasure is a website created by John Walker. It's about (hidden) indie gems. I'll be honest about it: reason I found out this site exists, is because my game was reviewed there. Nonetheless I check it regularly to see which games pop up. Here are three examples I really liked. Be sure to check the rest as well.
The developer did a perfect job: the game is simple, but very polished. It's not minesweeper. Is it? There is at least one difference, every puzzle can be solved by pure logic. No luck.
I couldn't find a trailer for this game on Youtube. You could however check this gameplay video by Fenton Bailey.
Not a puzzle, but a pinball game. This game is
chaos an experience. Check the video and you'll know if this could be anything for you.
Probably already played by anyone who reads this anyway. But first time I saw this game was on Buried Treasure. Then found out it was by the same person who made "HOOK". It's a minimalistic/relaxing puzzle game.
