Mystery P.I. - The Lottery Ticket is a downloadable hidden object game from PopCap Games. The description from their website reads: Help Grandma Rose retrieve her winning $488 million lottery ticket in this richly entertaining mystery! Retrace Grandma's steps and uncover clues by finding hidden objects and solving tricky puzzles. Earn big points for accuracy and climb up the P.I. ranks. Do you have what it takes to solve the case? I found this to be a rather interesting hidden object game. You start out with a couple of areas on your map to search. Not all of them are buildings and some of them are rather unusual. Once you have gathered the alloted number of objects needed, you are taken to a memory game. With each level you have more areas on your map to search and you have a different memory game to play. You start off with a typical 'match the cards' game but then you evolve to 'match objects with the same color' and 'find objects that go together.' This is really an amazing way to make this game different from other hidden object games while engaging the player as well. Since each level is so different, you have to pay attention to the rules every time.
In my opinion, this would be a great game for an adult to play with a child. The hidden object sections are hard enough to keep the adult interested while the child will do better on the memory side of things. I know my daughter beats me every time we play Memory. Even if you don't have any children to play with, this is still a captivating game.
