KAPLA Challenge is a quest for the perfect balance… Try reproducing the models pictured on each of the 12 “Challenge cards”, with the 16 KAPLA wooden planks at your disposal. “Both brains and hands come into play to achieve harmony and balance of mankind.” The KAPLA concept is simple. It needs no glue, no screws, no clips to fix the blocks. Each block is simply placed one on top of the other. The blocks are held in place by gravity and balance alone.  KAPLA is made of 100% natural and untreated French pine wood. The pine wood is grown in 100% sustainable forests in the South of France.
