# Kapla

A bridge structure made of KAPLA

Kapla ( original spelling KAPLA ) is a building and construction game made of pine wood tiles . The wooden tiles are placed on top of one another in order to implement a variety of building ideas. This game works without connecting or fastening elements.

## history

The name comes from the Dutch term for "Wichtelhölzchen", KAbouter PLAnkjes . Kapla was developed in 1987 while building a stone castle in the Aveyron department in southern France . When the then 25-year-old builder Tom van der Bruggen wanted to create a model of the building with conventional wooden blocks, the cube shape proved to be unsuitable, so he replaced it with wooden plates - and thus invented Kapla.

## Dimensions, properties and calculations

All wooden plates are cuboid and have the same dimensions: They are 117 mm long, 23.4 mm wide and 7.8 mm high. The sides are cut to a tenth of a millimeter. The aspect ratios can be formulated as continuous proportions : length, width and height are related to 15 to 3 to 1. This means that three Kapla tiles placed flat on top of one another are as high as one tile is wide; five platelets placed flat or fifteen on edge are as wide as the length of one platelet.

In reality, the platelets are usually 117.6–117.7 mm long. In this way, those somewhat larger dimensions can be compensated for, which in the real (as opposed to an ideal) world e.g. B. caused by small manufacturing inaccuracies, small burrs on the edges, slightly warped platelets or small air gaps between assembled platelets and which add up in a relevant way, especially when they are repeatedly lined up or stacked. In this way, the "stackability" should be preserved as well as possible, even with large or high constructions, without the constructions inadvertently becoming crooked (not orthogonal ) or wobbly.

A Kapla plate weighs on average 11.9 g.

## The structure

This game does not require a building system. It is sufficient to put the wooden panels on top of each other so that any buildings and even highly complex constructions can be created. Kapla can be combined in three ways:

• lying flat,
• on the side,
• upright.

However, certain constructions (with flat Kapla) can be viewed as a structural unit:

• Procedure as for building with bricks,
• arranged in a spiral and like a spiral staircase.

Since the wooden blocks are only placed on top of one another and not permanently connected to each other, only cantilever vaults are possible instead of real vaults , instead of real arches only cantilever arches are possible.

## Products

Kapla tiles are offered in boxes of 40, 100, 200, 280 and 1,000 tiles. They are available in natural colors (untreated wood), in red, orange, yellow, green, light blue, dark blue, in black and white, and since 2012 in purple and pink.

There are four art books from Kapla that playfully promote and see themselves as a source of inspiration for every builder.

## Records

The tallest Kapla building is a 18.40 m high construction inspired by the tallest skyscraper in the world, the Burj Khalifa in Dubai, which was built in Lyon on May 14, 2016 . Models of entire cities have also been built. The American city of Las Vegas was recreated by a Dutchman from 21,504 Kapla tiles.
