Abstract
An apparatus and method are provided for detecting malfunctions in an automatic card shuffler device of the type which randomly extracts cards from two or more storage wells. Detection is accomplished by sensing the failure of a card to be extracted for a storage well and counting the number of successive failures from each storage well. When the number of successive extraction failures associated with any one storage well reaches a predetermined value, an alarm is activated.
