Can anybody recommend any decent ones? I've played both of the Azada games (is the third coming out any day soon?). I don't enjoy the 'Hidden Objects'-type games, which seem to be the bulk of PC puzzle games available, so would really appreciate any suggestions. Thanks.
Pandora's Box is a masterpiece - by the creator of Tetris but completely different puzzle types. Came out a while ago so you can probably pick it up quite cheaply. 100% recommended!
