Following the 'Visual Power Memory Game', a new version of this brain teaser has been developed - 'Twins Memory Game.' This version is based on identical twins and the object is to find the most sets that are truly identical. Sounds easy, but be warned - identical twins are not always absolutely identical! To win this game you'll need to rely on a little more than your memory. It features thirty identical twins, photographed in the most natural of circumstances by Agnes Kappert. When you study the matching sets of portraits the similarities are instantly recognizable, but it's when you start to seek the differences that the fun really begins.
