"Puzzle Communication Nikoli" is a Japanese puzzle magazine started in 1980 (see http://www.nikoli.co.jp/en/ for Nikoli official website). A lot of puzzles were born in this magazine via readers' contributions, some of which (Slitherlink, Shikaku, etc.) are now regarded as "classic" in worldwide puzzle competitions like WPC. In this test, we would like participants to enjoy their beauty and depth.
There are 25 puzzles from 13 different types.
You may start "Japanese Puzzle Land" any time during the 48-hour period during the weekend of 20/21 August.
Your timer will start when you click "Start Japanese Puzzle Land" — then you will have 100 minutes to solve and submit your answers.
