Number type party game - has triangular cards bearing numbers of which participants must form closed group

摘要

The party game comprises a number of congruent flat units with a least one number indicated on one of their flat sides. At least four such units are formed into each of two or more groups, and they are triangular in shape. When the units are placed together in one group, the point angles are equal to summation to 360 degrees. The numbering on the units for each group is the same, and is from one upwards. By placing the successive numbers along a left-hand leg running out from the angle point, the next consecutive number is already positioned along the opposite leg.
