20 Puzzles

As you've probably gathered from its name, 20 Puzzles is a game in which you're going to have to solve different brain-teasers, twenty to be more precise. Well, they are really 20 different levels of the same puzzle that consists in clearing the table, removing all the blocks until there's only 1 left. How? Well, just like in checkers, jumping over one block with an adjacent one.
