Summary: Parents need to know that Splice is a puzzle game with a vaguely science-y theme and no controversial content. However, this doesn't mean that it's appropriate for all ages. The puzzles -- which involve reorganizing cells into specific patterns -- can be extremely challenging, and no tutorial is offered. There is a good chance it will leave younger players -- and perhaps many older ones, too -- fairly frustrated.
