It's time to hit the club and challenge your rivals to a dance competition like no other. It's up to you to take your b-boy moves to the tournaments through the exclusive use of the DS's stylus and touch screen. The way to perform moves is simple, yet increasingly difficult. As shapes appear on the screen, it's your job to basically play a timed version of "connect the dots" on the bottom while your b-boy works his magic on the top. Of course, you won't see any of the moves, because if you don't keep your eyes glued to the dots, you'll easily mess up and lose valuable lives.
The main "dots" that appear are in the form of different shapes and colors, and range in number and frequency. The goal is to connect as many like-shapes together as possible, and in as many different patterns as possible, before the timer runs out and a new set appears. You'll also gain bonus points and multipliers for connecting the full amount of dots in one fluid path, no matter how jerky your line ends up appearing. Doing so will not only give you more points immediately, but also at the end of a successful round. You can earn quite a few bonuses like this as well.
There are, of course, a couple of catches. The first is that if you let up from the screen as you're drawing, you will lose your entire line and have to start over. In the early rounds, this isn't that big of a deal, but as the amount of dots gets greater and greater, you'll need to connect the dots (and there will be a lot of them to connect) with definite precision. The other catch is that if you happen to run your line into a dot of another shape/color, you'll immediately lose a life. The gameplay action will not break there, however, so you can easily drop lives like bad habits if you get frustrated with a break in your drawing. The good news is that just because an unfriendly dot is directly in your path, you can actually draw a line around it and the path will continue uninterrupted.
Red Bull BC One is quite repetitious, so don't expect a whole lot of variety in the gameplay. There are a ton of music tracks, although they are all quite similar in nature. In the single player game, you'll have to battle through 8 stages, covering 36 competitions, each getting more and more difficult. You can also go head-to-head with a friend in multiplayer mode, but you will both need a copy of the game to do so as BC One does not support Download Play.
