Four King Cubes
Good afternoon,
With the ntention of signing up for some NATS testing hilarity later in the year, I'd like to practise some Cubes. I'm aware that I could be less lazy, and make some for myself, but I'm looking to achieve something different.
Is there a "trick," other than the rubber, to ensuring that you get a correct answer? I'd like not to cheat if possible, but there has to be some sniff of logic the the puzzles. If not, does somebody have a book or something full of Cubes to practise with?
Cheers,
Adam
