This is the handheld brain trainer that prepares the mind for any mental challenges, such as the notoriously ingenious puzzles of the New York Times. A Hammacher Schlemmer exclusive, it holds an entire mental obstacle course, from Hangman and anagrams to Sudoku and number squares, along with a host of word games, number and logic puzzles, and tests of memory to fine-tune the brain's performance. The 2" x 3 1/2" monochrome touchscreen is backlit for easy viewing and responds instantly to a touch from the included stylus. When a puzzle becomes too stubborn, a hint button offers a clue. Because puzzles are generated on the fly, an endless supply of fresh challenges is always at hand. Requires three AAA batteries. 5" H x 3 1/4" W x 3/4" D. (1 lb.)
