I posted a few months ago about how Sudoku had hit the UK – the wave has now reached the US.
Bored on a flight I tried them – and they are certainly interesting. The harder puzzles really appeal to my sense of problem solving and pattern matching.
So – somewhat addicted – I purchased some cool software – Soduko from SadMan Software.
Great – I’ve now got an endless supply of really hard problems – along with built in tutorial advice. It’s interesting – since reading up on some of the pattern matching concepts I’ve halved my time to complete some of the harder problems.
