Title: Treasure Map
In case you're wondering, the colors here were chosen for their significance: brown for dirt, green for grass, blue for the sea, red for blood, and gold for ... well, treasure.
The official rules:
- The digits 1 through 9 appear in each row and each column exactly once.
- Digits in each shaded region must add to the indicated sum.
- Squares with multiple colors contain a number that’s used in the sum for adjacent regions of each of those colors.
- Remember: numbers can repeat within a shaded region if that doesn't violate the first rule.
