I said earlier that
Quickspot has simple graphics, but even simpler is its gameplay. Though each mode has its own twist, the basic concept in this game is to find the differences between the top picture and the bottom picture and circle them with your stylus. That's it, no bells or whistles, just look, compare, circle. You would think that it isn't all that interesting of a game, but I found it to be a great game to pick up when I just needed a little break and wanted to get my mind off of whatever work I was doing at the time.
Quickspot has three single player modes: Rapid Play, Focus Play and Today's Fortune. Rapid Play is the one I was in the most and its the only one that might be considered a "Story Mode." Here you go through a series of stages and levels going through more and more pictures. Each stage consists of several photos in which you need to identify a difference. Once you have circled the difference, the screen changes and you have to do it again for another pair of pictures. Once you've found enough differences, you clear the stage and your brain activity gets analyzed.
Your brain activity is divided into five categories: Intuition, Concentration, Recognition, Stability and Judgement. How well you do in each category is based on how quickly you find the difference, how close your circle is to the shape of the distance, the number of times you don't see the difference, your average time to find the differences across the stage and how stable your circle is when you draw it.
As you progress through each level, you will also encounter boss stages. These are just like the normal stages, except you have to perform some other task before you can actually see the bottom image. In the first level, you have to rub the screen and reveal the bottom graphic. In another level, you have to blow into the mic in order to move leaves off of the screen. This added action really helps to make that last stage harder.
Focus Play lets you spend as much time as you like on the hundreds of images there are. In this mode, instead of looking for just one difference and moving on, you are looking for multiple differences. This is closer to what you might have played in magazines or comic strips growing up. Here it doesn't matter how exact your circle is, its just a matter of finding the difference and marking it. I couldn't help feeling like Focus Play was meant to be more of a practice mode for Rapid Play. That's what I used it for anyway.
Today's Fortune is a little different. Here you pick which fortune you want to read (Health, Work, Romance or Money), and you go through a series of images (much like Rapid Play) and based on which differences you saw (because in this mode, each screen has multiple differences), it figures out what your fortune is for that day. You can only determine your fortune for each category once per day.
Quickspot also has several multiplayer modes that do everything from having you pass the DS around, to multi-card and single-card play, so as long as you have a friend, there is no excuse not to play at least one of the multiplayer modes.
