Buy Fruit Cubes Online In India Fruit cubes (short for ‘modifications’) are puzzles that deviate from the original cube shape of most puzzles. When turned, they may change shape even further, and hence, solving them mostly involves understanding how the pieces move, and their orientation. Fruit cubes are those that eventually form the shape of a fruit when solved. They also make for great display puzzles, and are some of the most fun-to-solve non-WCA puzzles out there. Good examples are the banana, apple and pear puzzles.
