QuickSpot review

Focus Play is a more leisurely experience, with no time limit. Each Focus play is contained within a single set of top and bottom images, with many small differences in each set. As you find all of the differences in one screen, you can move on to the next, and there are well over 100 sets to unlock.

Like the single players modes, the two multiplayer modes are best enjoyed in quick play sessions. Time Bomb is played by passing one DS around, in "hot potato" fashion, where players take turns spotting a difference. Scramble, on the other hand, starts as a simple game of who can spot the difference faster, with up to four players. This by itself would get old quickly, but to make things interesting you can throw attacks at other players, like a censoring mosaic to scramble their screens and so forth.

You can play the Scramble mode with one cartridge, but you'll have to periodically pause to download new screens, otherwise you'll start to cycle through the same screens over again after awhile. This repeated downloading can be avoided by using multiple cartridges, but it's a small price to pay to be able to play with up to four people with one cartridge.
