Here's new puzzle with a simple rule set that I made for the holiday today. Fill in the diamonds with the numbers 1 through 5 so that each number appears exactly six times and 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.
