What's Herbert?
Herbert is a exciting puzzle game.
Your mission is controling the robot(Herbert) on the field and pushing targets.
You can use a simple programming language, "H" to control Herbert.
The grammer and rule of "H" is so simple that everyone can master it in short time.
Herbert is especially recommended for people who...
like puzzles / want to train their brains
intend to learn programming
are familiar with programming and algorithms
About Herbert and HOJ
Herbert was originally developed by wildnoodle.
It was used on Microsoft ImagineCup for three years.
This website is unofficial Herbert Online Judge system for Herbert lovers.
There are some differences between HOJ and original implementation by wildnoodle.
