Here's new style of puzzle with a fairly simple set of rules. Fill in the diamonds with the numbers 1 through 5 so that each number appears exactly six times and so no two adjacent diamonds contain the same number. A white circle between diamonds indicates that the sum of the numbers in those diamonds is five. A blue circle indicates the sum is six, and a grey circle indicates the sum is seven.
