Abstract: A promotional gaming device for determining whether a player has matched a predetermined winning sequence of characters or symbols. The gaming device is comprised of a substrate having at least one row of location designating symbols and at least one column of location designating symbols disposed in relation to each other so that a position may be designated by a combination of at least one of the symbols from the row and at least one of the symbols from the column. Groups of sequence representing elements are disposed on the substrate which represent elements having a corresponding position designated by the positional combination of at least one of the symbols from the row and at least one of the symbols from the column.

Abstract: A memory aiding device for aiding in remembering a predetermined personal identification number. A substrate has sequence representing integers predisposed on it in rows and columns for representing a personal identification number. Each respective sequence representing integer is printed at a respective column and row intersection. A user definable location is designated at an intersection of a row and a column and designates a set of sequence representing integers. A set of marks is recorded on a sheet member. Each mark indicates a respective numeral of the personal identification number represented by a corresponding sequence representing integer. When the recorded sheet member is disposed under the substrate at the user defined location, the personal identification number represented by the corresponding sequence representing integers is perceived by perceiving the marks.
