Luigi
Luigi, a.k.a.
Peter Krah, is not only the most industrious solver in the portal
(he wants them all!), but also the most productive puzzle author.
He will tackle every subject, and he frequently introduces surprising
new ideas or puzzle series. The Luigi effect
(L.-E.) is a humorous
term for occasional initial flaws in his puzzles.
Try Luigi's puzzles and have fun!
