Sorry for the late comment, but thanks for all participations and lots of positive feedbacks. And congratulations to Robert Vollmert for his dominant victory! My only regret is that I was sleeping while he was playing.

As we stated in the password, we've started working for Vol.4. If any readers have some suggestions to our book, such as "more hard puzzles", "less T&E puzzles" or any particular genre you want to solve, please let us know.

Here are two related links:
1. EKBM has posted his thoughts about this test in his blog (http://ekbm.blogspot.jp/). Logical solving path of Graffiti Snake 2 is beautiful and worth reading.
2. German website croco-puzzle (http://www.croco-puzzle.com/) is holding a daily competition of Toketa Puzzles. First two puzzles are New Tren by Silke Berendes.

Thanks James and Hideaki. James, you were definitely on the list of solvers that I was scared off while reloading the score page all weekend + Monday. And Hideaki, looking at the croco series, good thing you were test-solving!
