An international competition
held every October
, in which teams of 4 puzzle solver
s from various countries compete on a set of language-neutral puzzle
s, thus mostly logic puzzles
and math puzzle
The U. S. team holds a qualifier in June, and some other countries use this test in forming their teams as well. See www.puzzles-usa.org for more information. I will be trying out again this year, after narrowly failing to make the team last year. Wish me luck!
Wei-Hwa Huang is the most successful puzzlist at this event, having won the individual title 4 of the last 5 years.
