Tentropeapods (a ChinStrap birthday puzzle)
(Published on 3. May 2025, 23:06 by Calvinball)
This is a collab between myself and sujoyku, we wanted to team up to celebrate our friend ChinStrap and wish him a happy birthday!
If you have any questions feel free to DM us on Discord.
Happy solving!
Rules:
- Normal sudoku rules apply. Place the digits 1-9 once in every row, column, and box.
- Tentropeapods: Each line in the grid simultaneously is a Tentropy and a Peapod line.
- Tentropy Lines: Every set of 4 adjacent digits on a hollow peach line (including the circle) must contain a digit from each of the X-pair (ten-pair) subsets of {1,9}, {2,8}, {3,7}, and {4,6}. A 5 may not appear on a tentropy line. Digits on a line may repeat if allowed by other rules.
Peapods: Digits on a line sum up to a two digit number made out of the digit in the line's circle repeated twice. For example, 245 on a line would have a 1 in its circle.
Solution code: Row 8

What a great present from two great guys. These two constraints were very nice together. I am truly honored to know both of you!

Great puzzle! Missed the part about the circle being included in the constraint and that made everything harder for me for a little bit.
