Four Brainbusters in one. The pack is composed of a Sudoku Cube– a representation of the brain busting game, but in 3D! Twist and turn the rows on the cube so that on each face the numbers 1 to 9 each appear only once. Also included is Cube Words, where the aim is to arrange the letters on each cube face so that valid three-letter words are created horizontally and vertically through the central letter and along both diagonals. There is a Snake Cube where you must line up the squares to make an unbroken snake that winds around the entire cube, and finally a traditional twisting Colour Cube. Each cube measures 2" x 2" x 2". Set of four. Ages 5+.
