The target number of cells and their sum is entered using the edit tool. This presents a pick list of cells and sums values to simplify their selection and prevent invalid entries. It is also possible to select the display of combinations with duplicate values. Filter tools help reduce the possible combinations. Three variants of filter are provided namely: ・Exclude ・Include AND ・Include OR The exclude filter removes any combinations that contain the specified numbers.

Cage combinations can also be manually deleted. A calculator tool, optimised for solving Killer puzzles, is provided.
