We used to have a thread on this somewhere, so I thought I'd start it up again. I'm always looking for some good puzzle experience.

Casual games seem to be getting more difficult, some even giving you a 3rd Hardcore play mode with no access to hints or skips.

Here's my list of some recommended games if you like a lot of puzzles:

Alabama Smith Escape from Pompei
Azada
Drawn 1 ad 2
Dr. Lynch Grave Secrets
Eden's Quest Hunt for Akua
Echos of the Past Royal House of Stone
Fall Trilogy
Haunted Halls Green Hills Sanitarium
Hidden Expedition Uncharted Islands CE
James Patterson Death in Scarlet
James Patterson Women's Club Twice in a Blue Moon
MCF Ravenhurst
MCF Return to Ravenhurst
MCF Escape from Ravenhurst
Puzzle Bots
Sherlock Holmes Persian Carpet
Urban Legends The Maze

Grim Tales the Legacy

Temple of Life legend of 4 Elements

Blocks that matter was an interesting casual puzzle/platformer. Some of the later puzzles did get quite challenging though.
