Abstract: A letter placement game based on solving for missing characters in empty cells in a grid of characters. The grid includes horizontal rows, vertical rows, and subgrids. Each solution character must be singular in its horizontal row, vertical row, and subgrid. Simultaneously some solution characters must also belong to one or more sets of solution characters (for example, one or more words). Clues are provided for each set of solution characters. Typically, each letter placement game has multiple sets of solution characters. The letter placement game thus has dual sets of requirements, one for singularity rules for every solution character and another for the requirements of sets of solution characters (for example, words).

Abstract: A method and system for interactive product merchandising for an end user accessing a destination, such as a Web site, over a network, such as the Internet. The method includes extracting information pertaining to the destination and using this information to select a product to promote to the end user. Then heterogeneous information is collected that is related to the product, such as vendors, pricing, vendor ratings, vendor reviews, product ratings, product reviews, other related products, and other information. A unified display unit is composed from the heterogeneous information to provide an interactive user interface for the end user for presentation at the destination (e.g., displayed on the Web site). The method also tracks activity by the end user at the unified display unit to use as input in selecting one or more other products for another promotion to the end user. The method is aimed at encouraging impulsive buying by an end user who is browsing the network without intending to make a purchase.
