Author's note: After solving the excellent Build Your Own Sloop by Piatato and noticing how few tripleblocks there were on the site, I decided to create my own version —— with a twist. Beware of the math!

Rules:

• Shade three cells in every row and column, and fill every unshaded cell with the digits 1-9 in such a way that no digit repeats in a row or a column.
• The value of a digit is doubled for each edge it shares with a shaded cell. For example, if a 9 is surrounded by 4 shaded cells, its value is 9*2^4=144.
• The letters written outside of the grid are tripleblock clues. The first number gives the sum of the value of digits between the first and second shaded cell in the row or column, likewise with the second number for the second and third shaded cell. The number is treated as zero if the shaded cells are adjacent.
• Every distinct letter represents a distinct digit from 0 to 9. A question mark represents any digit, but for a double digit number, the first digit cannot be 0. To clarify, for a single digit number, it can be 0.

Example: Here is a more detailed example. In column 3, the first segment has no digit, so the sum is 0. The second segment 12=3*2^2. In row 5, the first segment 70=7*2^2+8+4*2+1*2+6*2^2 and the second segment 80=5*2^4.

Enjoy!
