Count calculation is slightly different from Count Items or Count game. In this not only counting of items is done but some calculation is required. There could be some different ways for this game. Multiple items can be placed in different zones, shapes. Calculation of items can be done based on following rule: Calculate Item 1 in Zone A + Zone B - Zone c. Another example could be Calculate Item 1 + Item 2 in Zone A - Zone B.
Another type of game could be where Zones are overlapping. Here, union and intersection can be done. Like Count Item 1 in Zone A Union Zone B which means if Item is coming in overlapping area of Zone A and Zone B then it has to be counted 1 time only.
