A contest card having a scratch-off contest area to indicate whether or not the user has won, and also having a skill testing question and a set of scratch-off answer sections. The user scratches off a single answer section to reveal an indication of whether or not the user has answered the question correctly. The scratch-off answer sections remove the need for a pen or pencil and also eliminate the involvement of the store clerk in the answering procedure.
