Scottish-born and South African-based author, Caro Eardley, spent three years developing the Win At Sudoku method and another year writing the book.

Her logical skills, honed during a 20-year career as an international computer consultant bolstered her belief that there just had to be way - a Simple and an Easy Way – to win at this infuriating game. So – she is stubborn like a megamule and prefers to do things Her Way - she just persevered in applying logic and organisation, combined with intense observation of how the numbers behaved, until she reached her goal: Winning Consistently!

Eardley was also determined to avoid scary mathematical terminology – many people simply shut down when stuff like Finned X-wings, Gordian Polygons and Turbot Fish were mentioned! She certainly falls into this camp: her brain goes into freefall at the mere mention of ‘N-1 possibilities’!

She was also motivated by the scale of fellow addict’s – and their partner’s and family’s –suffering. Over 14,500 internet searches for help with Sudoku were logged in November 2010 alone…

Eardley still doesn't get every puzzle right first time - hey nobody's perfect - but she always wins in the end! And she still loves playing the game…which is very important to her/ She’d never knowingly do anything to spoil the hours of fun to be had with this apparently simple, cunningly deceptive, and utterly addictive game.
