Perfect Throw
Otherwise know as an Ippon, a perfect throw has four main components: Speed, Force, Control and a fall that lands largly on the back

Pin
By holding ones opponent on their back for 25 seconds, the score of Ippon is awarded and the match is over. Holing your opponent 10 or more seconds can get you lower scores.

Arm Bar
Otherwise know as an Arm Lock the goal is to force your opponent to "tap out," by applying stress (and Pain) to the elbow joint

Strangulation
Much like the Arm Bar the goal is submission. You can suffer a loss from passing out or from tapping out.

Disqualification
Through unsportsman like conduct or a combination of lesser penalties.
