	There will be two types of questions in the game: free-for-all and showdown. Numbered questions indicate a free-for-all type in which all students participate. Numbered questions followed by an ‘S’ indicate a showdown type in which select students participate. All students attempt to correctly answer free-for-all problems as fast as possible. The first student from each row to answer correctly advances to the showdown round as a representative for his/her row. The first student to correctly answer the showdown problem receives a point for his/her row.		There will be two types of questions in the game: free-for-all and showdown.

	===Steps===		===Steps To 30 Minute Completion===
			Free-for-all questions take about 30 seconds to answer. Allot say 30 (more than necessary) seconds to one-click sort the answers and announce those who advance to the showdown round. The answer slide (with explanation) is displayed for the students to read while the instructor does this. Showdown questions tend to be even faster - often based off the same premise as the free-for-all question just before. It would be appropriate to allot 20-25 seconds for students to answer these and 20 seconds for the instructor to display the answer and mark a point for the winner.

	~~===The problem===~~
	Polymorphism Showdown is a quiz-based game that tests knowledge of polymorphism concepts with relation to inheritance. The goal is to familiarize participants with casting, overloading, and overriding. Questions use a variety of formats, including UML diagrams and code snippets, to acclimate participants to conceptual application and direct code application. Participants are required to think on their feet and answer quickly so that an active audience is maintained and learning continues.

	Polymorphism is the ability of a subclass to define new or share functionality with a superclass.		Polymorphism is the ability of a subclass to define new or share functionality with a superclass. A subclass automatically has possession of public and protected variables and methods in its superclass. These inherited variables and methods can be called directly from an object of the subclass without having to change type.

			===Overriding===
	It is also possible to redefine variables and methods within a subclass. In such a case, a variable/method defined in the subclass '''overrides''' the variable/method with the same name in the superclass. When called from an instance of the subclass, the variable/method defined in the subclass will be accessed instead of the one in the superclass.

When called from an instance of the subclass, the variable/method defined in the subclass will be accessed instead of the one in the superclass.

			===Overloading===
	'''Overloading''' is a technique by which a method takes on many forms. Overloading occurs when a method name is used multiple times, but each instance of the method contains different parameters. This allows multiple variations of the same action to occur depending on circumstances.		'''Overloading''' is a technique by which a method takes on many forms.

			===Casting===
	Polymorphism also allows objects of one class to be transformed into objects of another class. This is particularly useful when changing functionality in an inheritance relationship. An instance of the superclass’ type can be set equal to an instance of the subclass’ type without any conflicts in the program. This is because the subclass is a more specific class of the superclass. Moving from subclass to superclass, however, would be making the subclass more generic. A technique known as casting is required to perform this change. '''Casting''' objects is only valid when moving in a upward along an object’s hierarchy (up to the superclass). Casting cannot be used between objects on the same level of the object hierarchy, and casting is not necessary to move down the object hierarchy. By placing a superclass’ name in parentheses just before the object you want to transform, you are declaring a new type, or casting.
