Here's another domeSoku twist of the Somedoku ruleset from blackjackfitz. Hope you like it.

  • domeSoku: Fill each cell with a digit from 1-9 such that Box N contains exactly N unique digits, and the set of cells in relative position N also contains exactly N unique digits. Both box and position numbers are in western reading order.
  • Full Rank:
    • The digits on columns and rows, read in both directions, make a total of 36 nine-digit numbers.
    • Clues outside the grid indicate the rank in ascending order among those 36 numbers for the indicated column or row in the direction of the clue.
    • One or more equal numbers are considered to be at rank N when there are N-1 numbers of strictly lower rank. (For example, we say there are three numbers in rank 20 when there are 19 numbers of lower rank and the next rank will be 23, i.e. the ranks could go ⋯, 19, 20, 20, 20, 23, ⋯)
  • No two numbers on a yellow line may be the same or consecutive.
  • Digits joined by a red dot are in a 1:N ratio, for some integer number N. Different dots may have a different N value.

Hi there.. I don't understand if the box and the relative position cells are considered as the same group, or two different groups..? (i.e., could box 9 theoretically have a repeated digit?)

***

they are two separate groups, like row/col are for Somedoku.

Very fun solve! I feel it's closer to ~2.5 stars difficulty-wise, but a good time regardless :)
