What is a logic game?
A game where everything you need to win is right in front of you: no luck, no prior knowledge. You just think it through and rule out what can't be, until only one answer is left.
Logic games for adults
Sudoku Detective is a deduction game: each suspect says where they were and you place them on the floor plan, like a sudoku, until you find the murderer. Cases go from very easy to expert, and in the duel you play against a rival.
