Games with "logical" puzzles - an IFDB Poll

by Victor Gijsbers
RSS Feed

Some puzzles--like chess problems or sudokus--can be difficult even though you know all the rules. I'm looking for IF games with this kind of puzzle: you can get to know the rules by simple exploration, and then you still have to solve the puzzle through logical thinking. A prime example would be the time paradox puzzle of All Things Devours, but please point me to more games. (Lock & Key, on the other hand, would not be a game of this type: the interaction between the traps is highly unpredictable, and a lot of trial and error is needed to solve the game.)
