QuickSpot's gameplay is sweet and simple: you must quickly spot differences between two similar pictures displayed on the top and bottom of the DS. Think back to your days of perusing the "Hidden Pictures" in Highlights for Children as a kid while waiting at the doctor's office. It's like that, only way, way more fun.
There are two single player modes, Rapid Play and Focus Play. Rapid Play involves a series of pictures in which you must spot a single difference as quickly as you can to move on to the next picture. As you progress, levels get harder and the differences between pictures are more subtle. Different objectives are also thrown in as you progress, like having to rub the screen with the stylus to reveal the bottom image, or having to select the correct puzzle piece from the bottom that completes an image on the top screen.
Since a DS game wouldn't be complete without it, there's also a breakdown of your current "brain activity" levels at the end of each level, which seems like an unnecessary and hasty add-on. Fortunately, these can be skipped through and ignored easily enough.
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.
QuickSpot delivers exactly what it promises, nothing more, nothing less. Some may be disappointed with the lack of in-depth gameplay, but that's not what this game is about. For what it's intended to be, QuickSpot nails it. The art is always entertaining, with lots of shoutouts to games you know and love, like Dig Dug and Katamari, to name a few. We guarantee that there will be times when you have to wait ten minutes for a bus, that you'll be glad to have your DS and a game like QuickSpot.
