Consider this structure being imposed upon the "Olympic Rings" to create 15 regions.

Place one number from 1 to 15 in each region so that the middle top ring (

**Black**) has a total of

**Z + 2**while the other 4 total

**Z**each.

__Ring Values:__

1. A B F G [Z] 2. B C D G H I J K [Z+2] (Black) 3. D E K L [Z] 4. F G H I M N [Z] 5. I J K L N O [Z]

__Note:__Olympic Rings has fewer overlaps.
