In Krimskrams, the players help Sammy to tidy up his trinkets. All the various things are different sizes, however, and each will fit only in one specific box. Sammy has to go from box to box to see what might fit and then place the corresponding piece. To get that nut coin as a reward, the item must fit perfectly. The first player to collect five nut coins wins!
