Friday Puzzles #26

Today I’m a little tired, having stayed up far too late last night discussing the merits of what a championship should and shouldn’t be with Thomas Snyder. The discussion became almost tediously technical – e.g. if a championship’s “goal” is to find the “best participant”, then we’d better have a sound definition of what “best” really is, before attempting any sort of statistical analysis of whether a particular format really does find the “best participant”. I claim that no championship can reasonably hope to have that “goal”.

Anyhow I don’t wish to carry on that discussion here, I merely want to excuse my laziness: being tired means that I’ve had to take a little inspiration again, rather than come up with anything properly original. Any puzzle lover should be made aware of MellowMelon’s (aka Palmer Mebane) blog – an incredible site where he puts out some high quality logic puzzles on a daily basis. I can’t claim to have had a go at all of them, since there are only so many hours in a day but I have to say I’m hugely impressed.

One such gem is this nurikabe puzzle: http://mellowmelon.wordpress.com/2009/11/22/puzzle-107/. I’ve tried to put my own (incomplete) twist on his theme today – together with a few ideas previously seen in my own puzzles. Enjoy!
