Designed to be a digitized version of classic "spot the difference" puzzles, Foto Frenzy challenges gamers to look at two seemingly identical pictures and pick out minute inconsistencies between the two. Players look at the top screen as a reference photo while they use the stylus to circle differences on the lower screen. There are over 5,000 challenges spread across more than 200 themed puzzles, and those looking for multiplayer action can use a single DS cartridge to play with up to three friends.
