The Times: KenKen Book 1: The new brain-training puzzle phenomenon

Description

KenKen is the brilliant successor to Su Doku that’s taken Japan by storm. In collaboration with The Times, Collins – the no 1 puzzle publisher – are proud to publish it in the UK. KenKen is a brain-training puzzle based on logic and simple arithmetic. Perfect for all ages and highly addictive, KenKen puzzles challenge and entertain in an entirely new way. The puzzle was invented by a charismatic Japanese maths teacher, Tetsuya Miyamoto in 2004. The name comes from ‘Ken’ which is the Japanese word for clever and KenKen translates as‘square wisdom’. It’s based on simple arithmetic and each puzzle involves some or all of the following skills: addition, subtraction, multiplication and division. As with Su Doku there are clearly defined levels for each type of puzzle from beginner and intermediate to advanced and the puzzles can be on any size grid, from 3 x 3 up to 9 x 9. The puzzles improve numeracy, logical thinking, concentration and perseverance. Can you KenKen? Review: Cost - Expensive Review: Divertido y desafiante - El Kenken es parecido al famoso juego sudoku, pero se le añade un poco más de desafío. Hay que rellenar una cuadrícula de n x n cuadros con números del 1 hasta el n sin que se repita ninguno ni en filas ni en columnas. Además, dentro de la cuadrícula existen regiones que deben cumplir cierta condición aritmética dada por un número y una operador aritmético (suma, resta, multiplicación o división). Por ejemplo si en una región pone 8+,los números de esa región deben sumar 8. Fácil ¿no?. No hay que ser un experto en matemáticas.
