Misión #1039. David W. Skinner (USA) is one of the most famous and respected authors of Sokoban puzzles. From 1999 to 2010, he created over a thousand puzzles. This mission contains puzzles from the collections of Microban 01 and Microban 02. These collections are created by the author specifically for beginners. All levels in them are small, each demonstrates some basic technique. But all these levels are created so filigree and talented that they are interesting for advanced players. We emphasize that this mission was created as a training one, each stage is accompanied by explanations and tips to the level. In this form, the mission will be understandable and accessible even to those who have no idea at all from which side to approach sokoban.
