If any output cell does not match the corresponding input cell, it will be highlighted to show that candidates have been eliminated. If an input cell has been left blank, the calculator will assume any candidate is valid in that cell. If a set of input cell candidates has been provided, the calculator will display the corresponding output cells candidates - essentially a consolidaion of all possible combination placements given the input criteria. The calculator also displays a list of all mutual exclusions that wouldĮliminate all remaining valid combinations. The output will also show a summary of all candidates used in the valid combinations, any candidates that occur in all valid combinations and any candidates that occur in no valid combinations. The basic output will list all possible combinations for the entered parameters - any deselected combinations will also be shown with a reason as to why it is invalid for the entered criteria. Total made up of: allows the overall total to be broken down into two or three subgroups - so, for example, 12(5) could be constrained to making a 7(3) and a 5(2) - any combination that cannot also make the sub-totals will be deselected.any combination that contains all the digits in a Mutual Exclusion group will be deselected '12 13 24') entered here must not occur in a single output combinations - i.e. Mutual Exclusions: any groups of digits (groups of 2 or more, separated by spaces, e.g.You can enter a new Killer puzzle using the new designer - click on ' Enter new Killer. Any cells that are reduced to one possible candidate are solved. Unknown squares are filled with candidates - possible solutions. Click on Take Step to step through the solution. any combinations containing at least one of the digits will be deselected You can pick examples from the list above. Excluding: any digits entered here must not occur in the output combinations - i.e.any combinations not containing at least one of the digits will be deselected Including: any digits entered here must occur in the output combinations - i.e.The constraints section allows additional conditions to be entered that may affect the valid combinations.
