Sudoku Cluster is a logic-based number-placement puzzle. It is distinct from but shares some properties and rules with Sudoku and kenken
Rules:
• All classic Sudoku rules apply
• Some cells have numbers written on the top-left corner, Let's call them cluster-heads
• Divide the board into clusters such that
• Each cell belongs to one and only one cluster
• Each cluster has one and only one cluster head
• The summation of the numbers in each cluster must be equal to the number in the cluster head
Cluster Sudoku is like Kenken, with the following differences:
• clusters are not given
• cluster are either horizontal or vertical
• the only operation is add
