The key piece to the Ninja is making sure that you sit in the car correctly. While some will not be able to sit just right because of height, at 6'3", my head sits above the shoulder harness. That is the key in being able to enjoy this ride.
That being said, younger kids will still enjoy this ride because it will be one of the first roller coasters that a kid will be able to ride with inversions.
The Ninja packs in a total of four inversions with a complete loop, half loop/half corkscrew combo and the big ending with a double corkscrew.
Ninja earns its name at the very end with some jerky actions through the 360 helix.
