Microban (155 puzzles, revised April, 2000)
This is a good set for beginners and children. Most of the puzzles are small
and illustrate a particular concept. More experienced players should also
find them interesting, since they are as different from each other as I
could make them given their size. Sokoholics could perhaps time themselves
on completing the whole set. This set also contains puzzles which I thought
were interesting but too easy to include in my regular sets. (David W Skinner)
