Pic Pic is, of course, originally a Japanese puzzle game (as no other country appears capable of creating a good one), but unusually has been translated and relocated for English-speaking types. (Something we still dearly wish would happen for Slitherlink). Originally called the slightly less catchy PikuPiku: Toku to E Ninaru 3-tsu no Puzzle, it's three puzzle games on one cart. And they're all great.
One stands out - Drawing. But before Eurogamer gets to that, bear with them for the onerous task of describing a visual puzzle in words - it's never a simple matter.
