"Easier" ones include "Find three different numbers whose sum equals to their product" and "Find out which colors will be on opposite faces of a cube whose faces are shown unfolded." Among those Tim ranks "most difficult": "Eight Queens" and "Arrange dominos on a board so that none can slide and leave as many holes as you can."

Some let you change the size of puzzle tiles and other initial parameters.
