The Pangram is easy to make (see drawings above), the ideal size of the game is 10 cm3. You'll find below some solids to match with all 7 pieces of the puzzle. Try to invent another tridimensional figure to match by combining the puzzle pieces and send us your best ideas!

The Tangramboard
by Serhiy Grabarchuk

In this puzzle the classic Tangram pattern is merged with a 4x4 checkerboard. This gives seven checkered pieces; the pieces are one-sided. The object is to assemble different regularly checkered shapes. Some patterns possible to create with this set are shown below. How can they be assembled? Keep in mind that pieces are one-sided, and they can be rotated, but not flipped over or overlapped. The fact that pieces are patterned and one-sided add to the Tangramboard challenges and the solving process a totally new logic.

Some shapes assembled using all the seven pieces of the Tangramboard.

Brügner's 3-piece Tangram...

The Tangram-like puzzle below, called after the German mathematician Georg Brügner, is composed of three similar right-angled triangles that form a rectangle. The proportion of the sides of this rectangle is calculated in such a manner that the number of convex figures which can be put together with the puzzle pieces is maximal.

In fact, it is possible to form with this three-piece puzzle exactly 16 different convex polygons: 2 rectangles, 2 triangles, 2 parallelograms, 3 trapezoïds, 2 deltoïds, 1 quadrilateral, and 4 pentagons (see below).
