Cyphadoku: A New Challenge



Available from Amazon.co.uk and Amazon.com. Out of Print

192 puzzles in a paperpack format.
Designed and compiled by Robert Thackeray

Combining the addictive qualities of two much-loved and familiar puzzles, sudoku and codeword, with the added challenge of a wordsearch, cyphadoku is an exciting addition to the gallery of logic-based puzzles.

To be solved cyphadoku puzzles require the simultaneous application of two very different mental processes: decoding letters to find their numeric equivalents, and, through logic alone, establishing the unique position of both letters and numbers - a stimulating and satisfying work-out!

An original puzzle by Robert Thackeray, software input by Andrew Stuart.
