This acrylic puzzle consists of an "apple" that is made up of 12 elements, which are a combination of two units. There are 5 tasks to solve. Start by laying out all elements on a table.

Task 1: The main task of the puzzle is to construct a square using all 12 elements. Elements can be flipped and turned by they must not overlap. (Hence, Squaring the Apple!)

Task 2: 'The Tailor's Problem'. Fit all 12 elements on a 10x2 strip with cutouts as pictured on the instructions.

Task 3: Construct congruent shapes. Using the entire set of elements, construct two congruent shapes and the same time. Find at least 3 solutions.

Task 4: A difficult task. Using the entire set of elements, construct simultaneously six symmetrical shapes of the same area.

Task 5: 'Squaring the Pineapple'. Using all 12 elements you can construct a symmetrical shape with a void inside.

A great challenge created by Russian designer Vladimir Krasnoukhov.
