that a separate connecting element 17 e g in the form of a rhombus is created which can be affixed in the corresponding grooves so that a male connecting element or a plug part is created the difficulty in putting this toy together increases with increasing number of plug parts that must be connected by being put together with a corresponding plug socket or groove in addition the arrangement and number of plug parts or grooves acting as plug sockets on the individual elements 2 and 3 in each case can be varied moreover the divided arrangement of the two types of individual elements 2 and 3 may be varied the greater the number of single elements 2 and 3 is which require a specific positioning dependent on the nature of the individual elements and the arrangement and number of connecting means grooves projections the greater is the difficulty in joining them together since the corresponding female plug socket parts i e therefore the grooves and the plug parts fitting them must necessarily be found in order to obtain a complete connection to form the e g spherical toy body the number of block shaped single elements 2 and 3 in each case can be determined in order to obtain the desired toy body when joined together in addition the number and arrangement of the plug parts projections and plug sockets grooves may be arranged differently on the five and six side faces 14 and 6 respectively of the individual elements 3 and 2 in each case so that the difficulty in joining them together to form the toy body can be adjusted accordingly the individual elements 2 3 can preferably be designed with curved base faces 5 3 i e be shaped in accordance with a part of.
