This is a cheap, nasty hollow chess set inside which you can hide tiny objects. This is supposed to encourage children to play chess because each time they take an opponent's piece they obtain the contents. The creators try to get around the fact that taking as many pieces as possible is not the point of the game simply by saying you should hide the most desirable tiny object inside the king.As for the booklet, it consists of a skimpy review of each chess piece, with diagrams cluttered by an over-complicated system of symbols, including *seven* different graphic symbols for the 'WonderFillers' - these being three different stickers and four differently patterned jelly beans.That's all there is to it. The whole thing seemed asinine.GetNo Stress Chessinstead, it is cleverly designed and my five-year-old daughter and I play it very happily; without stickers or junk food.
