Here's a great idea for keeping kids quiet while having fun on long car trips and other boredom-inducing situations. This miniaturized Sudoku game will also help kids develop and improve their playing skills. The game kit has heavy board portfolio-style covers that open to present an attached, spiral-bound rule book and player's guide. The kit's inside back cover is a Sudoku puzzle grid. Also enclosed are red and black magnetic number tiles and a pen with wipe-clean ink for trying out temporary solutions on the board. The attached rule book also presents tips and strategies for winning that will keep beginning players interested and encourage them to sharpen their skill.
