Fruit Ninja Kinect is a very simple concept yielding incredibly fun gameplay. Similar to the mobile version, your sole goal is to slice through pieces of fruit as they fly across the screen. Single slices give you a few points, though you need to slice multiple objects at once to get a higher score. This is made harder by bombs, which are sometimes tossed in with the fruit, requiring a little patience and restraint rather than waving your arms around like a madman. You'll also come across power-ups, that either slow down time, launch more fruit or double your score.
The same gameplay carries through across all of Fruit Ninja Kinect's play modes: Arcade, Zen and Classic. Each mode adds a slightly different twist to the formula. For instance, Zen is a bomb-free slicing experience, while Classic lets you slice for as long as you want as long as you don't hit three bombs.
One of the few major bumps against Fruit Ninja Kinect is its length. It is unlikely you'll squeeze more than a few minutes of fun out of any play session. Similar to the mobile version, the game is fun in short bursts rather than long marathon sessions. Adding friends for co-op sessions extends the playtime and, in my opinion, is the preferred way to play. This is the sort of game where friends get together, act like fools and laugh it up.
If you're the competitive type, Fruit Ninja Kinect offers Leaderboards, allowing you to compare your scores with friends or players worldwide. There's also a slate of unlockable rewards, like new blade types and Avatar awards. New blades don't change gameplay other than giving you cool slashes on the screen, but they're a great motivator. Just seeing a locked award dangling in front of me was enough to keep me playing for a few more games.
